Update on Evo X suspension

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

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!


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.
