Ground Control
 

I have Ground Control ride height adjusters for the front and rear on my 95 Z28. Does any 4th gen springs fit these or do you have to have the Ground Control springs.

not sure, i went with eibach 500 lb linears from Sam Strano and 150 lb linear for the rears. also koni yellows to handle it

and his 35/23 swaybar set

still struggling to get the ride heights correct. small adjustments feel different. I'm trying the ole 26.5" front 27" rear at wheelwell high points but 26 3/8" F and 26.75 R also felt good but less comfortable ride

also have to consider your driver weight unless you can stack plates onto your front seat while you measure

What you need is a set of 10"/2.5"ID coilover springs up front. In the rear get a set of 11" or 12"/ 5.5"ID single pigtail rear springs.
I'd go with the Hyperco (Hypercoil) brand for all of them.
