Today with the help of a friend I ditched the Bilstein BTS springs and Bilstein Sport struts on the front. I replaced them with the standard Koni single adjustable struts, 560 inch pound nonprogressive springs and GC upper camber/caster plates. This new set up on the front kicks ass and I can't wait till I can afford to upgrade the rear. I'm running a 7" tall spring and it sits just a little lower than the BTS spring. I don't know what people were talking about but the 560 spring I'm running the front with the Koni rides great on the street. Yeah its firm but it isn't crazy stiff like I've heard people say it would be. I have a pair of 600 pound springs I may run after I get used to these 560's. I don't know if I got lucky and my ride height and spring rate along with the camber/caster plate is perfect for my car or what but even with the high spring rate the Konis do a great job. I used a coil over type spring without the adjusting collar, it just sits in the stock spring perch. Eventually I will be removing the stock spring perch and getting some adjusting collars but for now it is working fine even though it is a little ghetto
I'd post pics of how the car sits but it sits exactly the same as the BTS springs did, just now I have a higher rate spring.
