Well, I found 2 sets of springs, Eibach and ST, but I'd like a set of aftermarket (read thicker) bars for my Lumina(99, 9c6, has the F41 Firm ride). and maybe a set of strut bars. The guys @ 3800 Performance.com said 99 Grand Prix parts don't fit, ' cause the GP and the Lumina didn't share platforms till '00. So my question is, anybody have leads on: strut tower bars, sway bars and urethane bushings? Any help is appreciated!
