Thanks

I bought the 8" x 2.25 x 700# for my rear.

2 things to note: first, the rubber deforms over time, and that's not optimal. Second, with the rubber bushings, the initial suspension movement (both up and down) compresses the rubber which acts as an un-dampened spring -- the very thing a shock is there to counter act! Handling response for small bumps and undulations should be improved.

So are your fronts in the 900# range?? Wow very stiff, I guess you need it for the track though.

Thanks,
Dan

That's right, I still have my konis up front, which I think are at about the end of their range in the 375lb.in. springs. I guess I could consider doing the front struts too, but I'd like to get some more track and autocross time to get a feel for what the car needs next.... After driving Dan's car I'm thinking r-compounds and a new turbocharger!!
