I read read this correctly you are using the "yellow" Sport shocks. If so, make sure the C-clips for the rear are on the middle groove-that is the standard location. How you position the spring cups is also important. If still in doubt-Koni has a tech line you can call in Hebron, KY.
If you can e-mail a picture of the shocks on the car I can see if all is good. Our car (FOR SALE) came out perfect.
