I just replaced my tires, shocks, springs, body bushings, and will be replacing more of the suspension bushings over time (I have them all, just a matter of getting dirty enough to replace them all).
Car rides significantly better but no better then my 2004 Chevy Avalanche. If you are looking ofr a caddy ride, you need to spend ALOT of money re-engineering the suspension. If you want a BMW ride, you are going to have to spend ALOT MORE money re-engineering the suspension.
If there are other TR's that you have ridden in that feel better then yours, then start looking at air bags, body bushings and suspension bushings and you may be on your way.
NK!![/QUO
my gn is also a t top, some of the rattles make the issue probably seem worse (I need to replace wx stripping), but I rode in another stock suspension TR that seemed noticeably better. Maybe I'll look to replace the body pushings and suspension bushings as mine are probably original.
