I am running the Pfadt "race" durometer differential bushings (these were discontinued long before Pfadt discontinued their "street" version). I haven't had much problems with them so far, but then again, I'm not on the track every weekend like you guys!!! I've seen posts where Justice Pete (from Pedder's) has said there is absolutely nothing wrong with the design or capabilities of the OEM diff bushing. So....if I ever do have problems with these Pfadt units, I'll probably just go back to stock. ......There's probably a good reason that Pfadt stopped making them completely!?!?!?!?
