I mentioned my desire for some poly bushings to a fellow I autocross with/against locally. As it turns out, the shop he manages makes their own bushings for their BMW race cars. He was able to custom make some D-78 (somewhere between poly & delrin hardness-wise) oem-spec control arm bushings. Offset was an option, but although my car will see the track regularly, it's not going to be a dedicated track car.
