My 91 Z-28 has about 132,000 miles on it. I want to know if anyone knows how to make it feel tight like it was brand new. I think the shocks and struts have been changed once mabey. Would a front rebuild kit make a difference? I was looking at a pst kit. New shocks and struts do you think the springs are worn out the car dosen't sag or anything. How about subframe connectors and a strut tower brace. Did 91 z28's come with wonder bars? My car has about 3 rattles to it right now and I think I need new strut mounts how much are they? I don't want a harsh ride just a smooth one like the day it drove off the lot.
