Man I been battling qa1 coil overs. They send em with 450lb springs in the front but that is too soft for our cars. I have also tried 600lb but am getting some 550 hopefully they feel good
I got an 88 I'm wanting to put coil overs on. I to wonder about the spring weight. I want to race it on road courses so, it's got 15s and I want it to corner. Not too worried about the comfort.
Question, with the QA1 rears. Do they do as Viking? Coilovers on the rears, deleting the factory coil spring? Also, would you happen to know anyone that does a stiffer spring rate for front and rears? As I have a 79 impala Sports Coupe, slammed, and looking for a stiffer rate, as the car is getting setup for autocross and maybe some drifting.
