I got rid of the coilovers and Stillen camber kit and went with Progress springs instead. WOW! What a difference! The Progress Springs work perfectly with the KYB AGX's! I basically have an entire 4th gen suspension setup now.

The Ground Controls DO NOT work with KYB AGX's...at least not the 4th gen. That is where the knocking noise was coming from.

The drop of the Progress springs is not nearly as low as the GC's....but it is livable.

I will be selling the GC's and Stillen Camber kit on ebay....unless someone e-mails me a reasonable offer.....

By the way, how much is the Ground Control kit and Stillen Camber kit new?

 

Wow. I just called up Stillen and the Ground Controls sell for $450 and the camber kit goes for $325. That's pretty cool. They will be on ebay later tonight.....

 

rob van dam seems to be insterested on the GC......ask him....maybe he will take the whole set from ya,.
