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?

The Spohn Del-Sphere joints are very similar to the UMI Roto-Joints. My rear LCAs have Roto-Joints at the rear and the Howe rubber bushings (much stiffer than stock) at the front. I already had the Howe's or I might have tried Rotos at both ends. So far, I like them just fine, but it's too early to say.

For the PHR, good-quality teflon-lined rod ends are quiet and last a long time (it's much more rod-end-friendly than the LCAs), so there's no reason to look any further.

The 3rd gen rear Koni (which many use on 4th gens), you will need to disconnect the lower end, extend the shock, reach up and press the button on top of the shock, and turn it to one of the 4 detents. The 4th gen rear Koni adjusts from the top. The carpet is already perforated over the shocks, so you can use a sharp knife to cut along the perforation, lift the flap, remove a foam insert, and there's the shock. Put the foam back in, trim off any frayed fluff from the felt padding, and tuck the flap back down. It's nearly invisible. Or, you can lift the carpet.
