Well.... I'm not saying there aren't areo issues but the front end coming of the ground was just too much. I'm just stating the lack of issues I've had. Euro springs aren't that stiff and gas struts could be $19 Autozone specials that are Cadi soft. Sounds almost stock. I know I wouldn't take my Z31 over 100 as it floats around a little too much for me. Also how did you get a 4 wheel alignment. There is no toe adjustment on the rear, I see poly bushings but not eccentric or adj rear lca's. How much toe and caster are you running? Not trying to down your setup, just don't know.
Steering damper, huh?
