In addition to rebuilding my entire suspension, brakes and new bearings all the way around, I added koni adjustable shocks (reds) and a set of H&R springs. My 126 is a project car, not my daily driver so I only get to make progress at a snail's pace. I still need to refinish my 16" Lorinser rims and treat them to a decent set of rubber. After the rims, the car will need to be aligned. Even now, I notice a huge improvement in stability and body roll, the car is still very comfortable to drive. I'm planning on re-vamping the roll bar when I'm finioshed with the suspension and am ready to address my A/C woes (roll bar is underneath the A/C components).

good luck!
