ok, putting on my rousch Lowering springs 2-morrow. I have read all the threads about the bushing issue ie; poly/spherical/segmented poly Bushing etc; I dont track my car or drag it, light to light well,,ok. I just want the next step up, so after reading all those threads, i've decided to stay with rubber bushings, just step up to the gt500 ULC's they are better than stock, no binding, and the other issues, and the gt500 ULC's seam like my fix, #1 they are rubber. #2 they are a step up. enough said ? anybody have these gt500 ULC's, how have they been doing, any problems with'em.
