I recently bought a car to start trackdays and Autox. Its a 99 Z28 with Strano Springs, 1LE front bar stock rear bar. Koni Da on front Sa on rear. Spohn LCA in rear with the matching PHB(Poly bushings). Poly bushings in all swaybar mounts. Totally rebuilt suspension in front.

The fronts are set 4 clicks from full soft on compression, havent checked rebound. Havent checked the rears they are all supposed to be out of the box installed.


I have been feeling the car out, I recently pushed it on an off ramp near home, car has good grip but if you hit a bump with it loaded it WILL get your attention. Car is all over the place you immediately start fighting the car. Its done it 3 times now.

No bumpsteer kit on the car for reference.

How do you adjust the SA rears? How do you adjust rebound on the front DA?

Good catch Josh, I missed the poly in the LCA's and PHB. That's the first thing I'd change. I'd also verify that there are bump stops on the car and I'd add some rebound to the car. Probably 1/4 of the total travel down from "full" rebound on both ends (and fine tune from there). I typically ran about 4 clicks of compression on the front of my 4th gen with 600 in lb front springs and DA shocks. So I won't say you're wrong to try that setting, I had good luck with it (but opinions always vary).

Beyond that, I'd start looking for a dead shock that's leaking or broken (you may not always see that from the outside). But I'd start at the top of this list first.
