Critical Damping in the Real World

2009-10-30T12:55:00.000-07:00

Driving the Evo around the other day I discovered science and the street actually in concert! Here's a short paper I wrote on the experience.

AST Stickers are highlight of SCCA Video!

2009-10-06T18:39:00.001-07:00

The 2009 SCCA Solo2 Nationals was the breakout event for AST Suspension. If this independent YouTube video is any indication of the popularity gaining with ASTs, I'm not sure what is. Pay attention to the large number of AST stickers on various makes and models. . Nationals video.

Ian Stewart Takes Home NASA TTC Championship on AST 5100s

2009-10-06T07:22:00.000-07:00

When points matter most, AST delivers. As does Ian Stewart! Ian built his National Champion Mini Cooper with the best of the best. Ian needed the best suspension money could buy BUT he needed it to fulfill the rules of NASA's Time Trial classes which have point values on adjustments and dollar amounts. Accrue too many points and you're in the next fastest class. Naturally we suggested AST 5100s which use the same competition parts as our 5200 two way remotes and 5300 triple adjustable shocks at a lower price point. Ian proved that good driving and single adjustable shocks can (and do) win at the national level. You don't have to "break the bank" to win. Thanks again Ian!

RobiSpec wins Redline Stock AWD and Overall Stock with AST 5200s!

2009-10-06T06:59:00.000-07:00

RobiSpec was in full force at the Redline Time Attack event Round 7. Robert "Robi" Fuller piloted his new '08 STI complete with AST 5200 Suspension. Robi, known for his suspension tuning with another shock company, took the STI out on its maiden voyage with AST dampers and took home the win in class and Overall Stock class as well. Robi said, "The shocks were great right out of the box. The car had so much grip, I didn't have to adjust them all day." We can't wait until he dials the car in for the Finale at California Speedway.

Thanks to the RobiSpec team for brining home the win. Good luck at Fontana!

AST USA Adds Track Notes Section to Website

Porsche 997 finishes 4th in Class at Nurburgring

2009-09-03T06:18:00.000-07:00

AST Suspension has been testing a new 911 coilover kit with Toyo Tires and Lammertink Racing. Initial testing proved the car was a winner besting lap records at various tracks for the class. Last weekend the team finished 4th in class. Look for more information on Porsche 5000 series kits soon!

Ian Stewart does it again!

2009-08-11T10:21:00.001-07:00

Ian traveled up to Road Atlanta last weekend to run with NASA in his TTC Mini Cooper. You might recall that Ian shattered the track record at Sebring by 3 seconds. Well, he did it again at Road Atlanta running a 1:39.4 in 98 degree heat. Ian is using the AST 5100 off the shelf kit with Vorshlag camber plates. Ride along with him here.

Leichty does it again! Wins Redline Time Attack!

2009-06-23T08:27:00.000-07:00

Aaron headed to the track again with his "almost stock" Honda S2000. Aaron is our first tester for Honda S2000 shocks running an off the shelf AST 4100 set. Aaron beat his nearest competitor by 2.4 seconds. Congrats Aaron!

Results here.

Turn In Concepts Wins Redline Time Attack on AST Dampers!

2009-06-22T13:27:00.000-07:00

Turn In Concepts, a Subaru shop selling AST shocks, won the Street AWD class this weekend at Redline's visit to Autobahn Country Club. TiC's customer car had a blown shock from another shock company and replaced the set with a test set of AST 4100s which were over two years old. Needless to say, the ASTs aren't coming back off the car after this win! TiC will be competing in several Redline Events this year. We hope to meet up with them at Nashville.

For the full details go here.

Ian Stewart breaks Sebring Track Record on ASTs!

2009-06-22T09:12:00.000-07:00

Don't tell Ian Stewart that it is hot outside, he doesn't care. Stewart set out to break the track record in NASA's TTC class running a 2:33.2 in 105 degree heat this past weekend. The previous record was 2:35.7. Ian wasn't happy with the record so the next morning he went out and ran a 2:32.1 beating the record by 3.6 seconds! Great job Ian!

If there was a track that required good dampers it is Sebring. Known as one of the bumpiest tracks in the U.S., Sebring has long been a torture test for race cars. Ian makes it look easy with this lap. Ride along with him here.

Ian is running the AST 5100 kit for the MINI Cooper. 5100s are single adjustable (rebound only) shocks. When we first started working with Ian, he wanted a high performance shock without the sky high prices of double and triple adjustable shocks. The 5100 was a perfect trade off in performance and value using competition level components in a single adjustable (non remote) shock. He's quoted as saying they work better than "any $7,000 shock I've driven on at less than half the price." Thanks again to Ian for showing off what a great driver on great shocks can do.

Aaron Leichty beats TTC track record by 3 seconds on AST 4100s!

2009-05-19T08:01:00.000-07:00

Aaron Leichty, one of our first Honda S2000 testers, beat the Putnum Park track record this weekend by THREE seconds. His time was good enough to beat the TTB track record as well and come within 0.5s of the TTA track record! Congrats to Aaron on his FIRST weekend in the car. Ride with Aaron on a lap around Putnum Park as he keeps up with Corvettes and Saleen S7s, eating them up in the turns. Click on the picture to see his fast lap.

AST's in action during Camaro Mustang Challenge Race

2009-05-18T09:23:00.000-07:00

Test driver, Jeff Wirtz, pulls off another winning weekend at Texas World Speedway in College Station, TX. Here's some video of the inverted start and Jeff passing the entire field during the 20 minute race. Jeff won the previous race which means the next one has an inverted start where 1st place is last, etc.

Way to go, Jeff!

AST Driver sweeps NASA CMC Event

2009-03-18T06:43:00.001-07:00

In his debut event on AST 4100s, Jeff Wirtz of Round Rock, TX pulled off a sweep at the NASA event at Motorsport Ranch. Jeff was always a top finisher last year, but with ASTs on the car Jeff put multiple seconds on the field in 4 of 4 races. This included inverted starts where he passed the whole field in the opening laps! The only car faster than Wirtz’s 3rd Gen Camaro was a fully prepped Mustang AIX classed car (a much faster class).

Camaro Mustang Challenge is a popular class in NASA that is growing especially in the Texas Region. Wirtz was able to drive a competitor’s car in practice, a car having twin tube shocks. “I felt bumps on the track with the twin tubes that I didn’t even know were there with the ASTs,” said Wirtz. AST’s monotube technology can provide forces greater than many lower end shocks without the harshness most drivers experience.

Congrats to Jeff in his first event with the shocks. Stay tuned for the April event at TWS in College Station!

RRT Suspension wins on AST 4200s

2009-02-27T10:48:00.000-08:00

RRT Suspension recently made their debut event with their "do it all" BMW E36 running AST 4200s with Vorshlag camber plates. The 325i was built specifically to compete in NASA GTS 2, SCCA ITR, and BMW Club Racing Prepared class. The "do it all" car came out fighting last weekend at VIR. Due to an issue with qualifying run groups, RRT's Barry Battle was forced to start in the back. Their forum has a video of the 10 lap race where Barry passes the entire field in the first 3 laps and then puts 40 seconds on 2nd place by the checkered flag. The car looks hooked up once he gets through the crowd. We think that must be a combination of driver and suspension since the car has the originally 200k mile motor in it! Great run Barry!

E36 M3 can still kick butt on the 'Ring with less power and WAY less money.

Update on Evo X suspension

2008-12-22T12:16:00.001-08:00

Quick update on the Evo X suspension. We're waiting on rear top mounts to test with the rear suspension, but we had enough time on Friday afternoon to get the fronts on.

We installed our new camber plate and AST 4200 double adjustable shocks. For this first install we used Hyperco 7", 450 lb, 60mm ID springs. Not sure where we'll end up but that's where we'll start. The AST 4200 is an internally adjustable, monotube, nitrogen charged damper designed to meet rule requirements where external reservoirs are not allowed.

The spring perch was moved up to almost seat with the spring platform when installed. This lowered the car approximately 1" from stock. I didn't want to lower it too much with stock height still in the rear. We'll finalize various spring height combinations depending on what dealers and customers ask for. Yes, we're aware of driving with such drastically different rates and how that affects handling, ride, etc. This is just to test fitment, etc. We'll put the package together and head out to the track over the holidays if all goes smoothly.
We drove the car over the weekend, granted all the testing was street driving on 5 clicks from full soft rebound, 0 on compression. We have 12 clicks total rebound and 12 clicks compression. The car rode extremely well passing the "spouse test" with flying colors.

Here's where it sits at the moment. Lowering the front really helps visibility. The Evo sits up so high, us shorter torso folk can't see over the huge, flat hood. :)

AST 4200s Compete in 25 Hours of Thunderhill

2008-12-15T15:02:00.001-08:00

Congrats to the Castrol/Speed Trapp Team for running AST 4200s on their BMW 3 series. The team posted the 2nd fastest lap time in their class but unfortunately had unscheduled brake wear stops putting them back to 6th. Anthony Zwain states, "The AST's worked great and lasted the entire race without an issue, thanks! There was only one other team (the class winner) faster than our car. They had another company's triple adjustable shocks and spent about 3 times what we did in car preparation."

Back from PRI!

2008-12-15T14:57:00.000-08:00

We made it back in one piece from Orlando. What a great show. We met many new shops and racers from around the country and globe for that matter. One display were several current and new models from AST. The rally "jumbo" shock was a hit with those passing by along with the new Corvette coilovers. These new coilovers will be the most complete set on the market. There was nothing but positive comments on them.

There will be several videos recorded from the booth we'll link here soon.

Update on new models

2008-12-04T09:29:00.000-08:00

We are currently testing the following new models:

NA/NB and NC Miata MX-5 4100 coilovers
2005+ Mustang 4150 coilovers
2008+ Evo X coilovers
C5/C6 coilovers

Ride along with Scott B during his GTS3 win on AST 4200s

Scott B's GTS3 win at NASA Championships

AST Wins at NASA Championship

2008-09-15T14:08:00.000-07:00

Well, we’re back from NASA’s Championship at Mid Ohio. First off, NASA announced that next year’s Championship will be at Miller Motorsport Park near Salt Lake City, UT. That’s only 1400 miles for us in Dallas, Texas. The event started out a soggy one. Most TT drivers didn’t bother running on the wet days since the best lap counts. But luckily, things started looking great Saturday and Sunday. The track dried Saturday and afternoon run groups had a clean, dry track. Conditions stayed good through Sunday as well if not for a little WIND. Can you say Ike? Yes, even Ohio is not immune to tropical depression winds. I saw more than one canopy go into retirement for this race season.

AST customers sponsored by Elephant Motorsports and Matthew’s Auto Sales brought the hardware to Mid Ohio in the form of AST 4200s and 4300s mainly in the GTS category. Special thanks to the crew at RRT for letting AST hang out at the compound as well. RRT is in the process of building a GTS/ITR/J Prepared car using AST 4200s. The car debuts next season.

In the end, Scott Berkowitz took home GTS 3 in a BMW M3 running the Vorshlag/AST 4200 suspension kit. Scott beat most of the field including GTS 4 and 5 cars (faster cars) finishing 5th overall in a field of 47! Shea Burns, John Van Houten, B.J. Farmer as well as Vorshlag customers Andy Watts and Barry Battle running Vorshlag camber plates all gave it their all this week. Andy took the GTS 5 win and overall GTS category win. Congrats to Andy! RRT brought several cars to the event with top finishes running Vorshlag parts.

Thanks to all our customers who took the chance on a new product and showed the competition what we can do.

We'll be attending the Texas Region NASA event at Eagle's Canyon with the Alpha car and our new Evo X in TTB.

As I write this, Terry and Amy have finished their first practice day at SCCA Solo2 Nationals. Terry was running strong in XP with our 4300 shocks while Amy was hanging with the STS Open top drivers in our 318is with custom 4300 shocks. Both cars are handling extremely well. Other AST cars at Topeka include an A Stock WRX STI, a DSP Impreza 2.5 RS, a STX E36, a STU WRX STI, and an XP Miata (our first Miata application). We’ll provide more of an update later this week. Stay tuned!

Vorshlag "Alpha" car gets ready for SCCA Solo 2 Nationals

2008-09-01T19:55:00.001-07:00

Vorshlag completed the final testing for the SCCA Solo2 Nationals this weekend. All systems are "go" including the AST 4300s keeping the suspension stuck to the ground. Good luck Vorshlag!

Vorshlag/AST land an Evo X MR!

2008-09-01T19:49:00.001-07:00

We asked ourselves, are we crazy? Surely this can't be done? But what if it could? What if you could daily drive your autocross car, your track day/time trial car, AND have it be spouse and family friendly? No, that is definitely crazy!

Sure, most of us can get by. We can make sacrifices. Heck, I drove a '07 STI around town with a side pipe and no muffler all for the "sake of winning". The downside? Well, no one would drive with me, but sometimes that's good. Hey, it was light! We've all driven cars with 750 lb/in springs and twin tube shocks on the street because we couldn't afford a truck and trailer. No it doesn't ride THAT bad...does it? We've pulled the A/C out of cars in Texas to drop 30 pounds before a big event. The list goes on and on. You know who you are.

In this time of high fuel costs and tightening spending, we believe the trend of multipurpose cars will become more and more important. With gas over $4 per gallon in some places, you begin to feel the crunch when you tow a car 1400 miles to an event. When the pump shuts off at $100 and you haven't finished filling up you begin to ponder, is there a better way? I don't think as "car guys" we're about to roll over and pick a new hobby. Sure, basket weaving is relaxing, but nothing compares to wide open throttle acceleration or making yourself keep your foot down through a 100 mph corner hoping it sticks this time. No, not many hobbies compare to cars. We want to have our cake and eat it too.

So, if we could find this "car nirvana", what would it be? What would it look like and what classes could it run in? What are some nice to haves? Lists are subjective, but we had some ideas. It needs to be a smaller displacement motor so probably turbocharged. It needs to have 4 doors, gotta carry people too. All wheel drive could be nice, how many times do you lose in the rain? It happens when you bring a two wheel drive car to the event ask me. One problem though, we LIKE the way rear wheel drive cars handle. Of course we want to make parts for it so it has to have a little "left on the table" from the factory to improve on. It needs to run on street tires. Forget towing a tire trailer and changing tires at the track. We're lazy and 18" race tires have gone from pricey to astronomically pricey!

That starts the conversation and narrows it quickly in our minds. Street tires - SCCA autocross has some very nice street tire based classsing structures. We're familiar with that. NASA TT has some nice classing as well that accounts for treadwear. A plan wouldn't be complete without hoping to run One Lap of America and a return trip to the GRM Ultimate Track Car Challenge to boot! Don't forget Redline Time Attack and Super Lap Battle. All possibilities.

Again, this may be subjective, but we think we've found a car that can check all our boxes. Friday we headed over to Don Herring Mitsubishi in Irving, TX and test drove some Evos. By Tuesday the next week, we picked up our 2008 Mitsubishi Evolution X MR in Wicked White as they say. You might say, "yikes, but you didn't factor in price tag?" Yes, the price of entry into the Evo is a little steep, bordering BMW levels. But if you step back and look at the package (and magazine articles) the Evo is a relative bargin to the cars it gets compared against. All the major magazines have done "track car" articles and the Evo is coming close to cars that start at $25,000 MORE than the Evo. It has brakes, power, suspension, and again, checks off our wants and desires. Better yet, it leaves room for improvement on suspension and power! But what about fuel mileage? More on that later. We plan to improve the abysmal mileage the Evo eeks out.

In short, we'll be combining the strength of Vorshlag and AST along with a few key partners to build what we feel is the Ultimate Dual Purpose Car, Project UDP. Short term planned mods include Vorshlag camber plates, AST 4200 coilovers, turbo back exhaust, and ECU tuning by Cobb Tuning. Stayed tuned for more!

Ready for stickers....

AST Suspension to race in 24 Hours of Dubai

2007-12-14T08:37:00.000-08:00

The race season kicks off this year on January 10th in Dubai with the third annual 24 Hours of Dubai. Over eighty race teams from around the world converge at the Dubai Autodrome circuit. AST Suspension not only is a sponsor of the event, but will be represented by the Creventic BV team running the first ever endurance prepped Audi R8, called the CR-8. The complete story can be found here.

AST developed a suspension setup based off the highly successful Competition model found in its current line up. Creventic BV will be building turn-key endurance race cars using AST's triple adjustable race suspension. This same suspension is available for popular Japanese, European, and American sports cars. Best of luck to the Creventic team in their debut race!

Back from Performance Racing Tradeshow!

2007-12-09T19:02:00.000-08:00

Well we made it back in one piece. Let's hope the shocks do too! We had a great time meeting old friends, new friends and having a great time outside the show too. We'll do a more detailed update later, but it was a great launch for AST in the States. Special thanks to AST BV for coming over from Holland and helping with the show.

We had some very influential industry specialists coming by to see the products and sending still others by to see the products as well. They were very complimentary of the product quality and the innovation that our new double adjustables have with the TPDA valving for compression adjustment. Some special topics we'll follow up with on the news section:

TUV testing: What does it mean to you when you purchase a race quality shock?
New applications: We'll update a list of cars we're looking for to test new products on.

AST 4200 Video

2007-11-02T14:07:00.000-07:00

Straight from AST...

The following video is the raw footage of video we'll be showing at our booth for Performance Racing Industry tradeshow (in Orlando December 6-8). We'll clean it up a bit.

This is the AST 4200 double adjustable damper on the shock dyno. The 4200 is based on AST's Twin Piston Dual Adjust (TPDA) technology. Simply put, TPDA moves the external reservoir into the base of the shock. The lower piston you see acts as the bleeder valve that a normal external res shock would have at the top of the reservoir. This controls the pressure put on the floating piston. With the valve open, the floating piston does its job and moves up and down as the shock runs through its stroke. The compression piston is stationary with relation to the body of the shock. As you change the adjustment for compression, the pressure increases in the main body of the shock and creates more compression damping.

This particular shock is using the red synthetic oil designed for viscosity stability in endurance racing. Plus it shows off really well for the video. We can build or rebuild shocks with this fluid for special applications. This technology is proven and has been used over the years.

http://www.youtube.com/watch?v=5vDiDUpQHfY

We have the AST 4200s in stock for BMW E36. Applications for E46 and other models can be specially ordered at this time; We will begin to stock as many models as possible. Of course "eye to eye" style shocks are easily done (see pictures below). E30 front 4200 doubles always present a challenge since we need the uprights to build them. Anything is possible, though.

Back from SCCA Nationals and BMW O'Fest!

2007-10-07T20:01:00.001-07:00

Well, we made it back in one piece from our trips. Back to business as usual. Amy Fair brought home a National Championship with the AST sponsored E36 M3. This car runs our new 4200 design. Way to go Amy! Our guys didn't fare too well this year. We had hoped for better results, but late August testing gave us some things to worry about. Unfortunately we took some gambles that didn't pay off. That's racing as the say!

BMW Oktober Fest was a blast. We ran the new LS1 powered E36 at the Day 1 and 2 autocrosses. This car has 4100 shocks on it at this time. It brought how top time of day by 6 seconds on Monday and TToD by 4 seconds on Tuesday. Good job!

We're running full speed ahead for the PRI show. We'll be in booth #1407. AST (Holland) will be coming as well to help with the booth. Stop by to meet some of the brightest minds in the damper business. We'll be showing off our latest designs. More to come.

AST USA Update!

2007-09-23T20:48:00.000-07:00

Greetings,
Just a few things going on. September 25th through October 2nd we'll be out of the office attending SCCA Solo Nationals then running back to Texas for BMW O'fest. If you're at either of these events, come find us. We should be around! We're bringing a Subaru WRX STI, Evo IX, and a BMW E36 M3 to the SCCA Solo Nationals. We've got AST 4100, 4200 and 4300 dampers represented on these cars.

We'll have the LS1 powered E36 318is out at O'fest running AST 4100s. Hopefully they won't kick us out for our non-BMW motor swap. :) This is the soon to be "track day" monster. Most folks that ride in it say they had "a religious experience" when they get out. 750 pound springs and the ASTs soak it up like nothing!

Several product projects are going on as well. We're working with some top customers on an enduro version of the 4200s, 4300 coilover rear E30 M3 shocks and various STI and Mini Cooper updates. E30 non M coilovers are being tested soon.

Reviews from new customers continue to come in. Customers are going faster at the track than they were before they installed their ASTs. That's the way we like it.

Thanks,
Brian

Testing on the 4200 series

2007-09-23T18:03:00.001-07:00

Testing on the new 4200 series shock is complete! We have completed testing of the new 4200 series shock using our TPDA technology. This double adjustable monotube with no external reservoir will be rolled out throughout our product line throughout the year. Subaru and BMW applications are ready now.

Welcome to the AST USA Blog
