Basically I need to replace my bushings and I'd like Delrin if anybody knows of a source that makes them. If not I guess I'll settle for powerflex poly bushings. Asura's bearings would be amazing, however you can't run in SP or ST autocross classes with metal bushing replacements and that is a concern for me. Also, I've heard that Spoon and Mugen make a bushing replacement for the front lower arm rear bushing, but I'm having a are time finding it.
