While I had the rear suspension out ( Installing the new Quaife TBD & Lowering the car with Kleemann Springs) . I started to look at the Anti sway bar bushings. They seemed a little soft? . I went looking for just some commerically available replacements , that were exact bolt- ins. I couldn't find them , in the time spand of 2 weeks of seraching , and I needed to finish this project. So I made my own . I used a poly urethane boat trailer , keel rooler ,made by STOLTZ. Model RP-5 (5"). They are TOUGHER than Hell. Stuck it in the lathe. Matched the IDs & ODs. Drilled them for Grease Fittings. Drilled the metal clamps to match & align with the grease passages. The grease fitting was long enough ,on the threaded end to match the counter sunk hole in the new bushing and to keep it from turning/working/walking around under up loads.so far no Squeaks. ride is not harsher . Here are some pictures

Good job, does it handle any better?

I've got no real way to measure it at this time. But on the street . It seems to take longer for the esp to get proactve. The suspension seems to be more compliant over rail road tracks
