PascoZ28

I've got a 96 Z28 with Edelbrock coilovers in front, Eibach Pro-Kit springs with Edelbrock shocks in the rear. The setup has 60K+ miles on it. I really want the rear to be about 1" lower and stiffer. There are numerous other mods which I won't get into for brevity's sake.

The car is my daily driver but is also used for autocross.

I was thinking about some KYB AGX's for the rear (price is right)...but what springs do I need to bring the rear end down 1" from the Pro-Kit height?

Any input/suggestions? Thanks.

Mike
