What do you guys thing a good tire pressure for the street is? Between these tires and the bilstein cup suspension, its alittle harsh, and I thought if I lowered the tire pressure alittle it would help.

 

i run above what's advertised in the manual, always have on every vehicle, less rolling friction.

What springs are you running on the car. If they are coil over springs like hyperco they are single rate springs and will be harsh. There is a thread on here about making progressive rate springs for coil overs out of a set of 8 inch and 4 inch springs and a helper spring collar. You need 2 4inch 350lb and 2 8 inch 400-500 lb springs and the collar for the helper springs. search the threads and the write up have part #'s and everyting you need. Poster said it's night and day difference.

 

I am running hypercoil 450 fronts, and 550 rears.
