My new TC6 has a major chassis tweak problem that I can't figure out. The rear right corner is a good 2 mm higher than the rest of the chassis. I've loosened and tightened everything on the chassis and nothing has helped. I also replaced the ridiculously tight ball ends that no amount of squeezing would loosen up. Has anyone else had this tweak problem? What should I do now? A complete rebuild? It's not possible for a chunk of carbon fibre to have a permanent bend in it, is it?
