I'm no tire or suspension expert so hang with me. I'm running Supercorsa SP's at the moment. I seemed to have had really clean tire wear the first couple track days on them (prior to new suspension). When I upgraded the suspension I started noticing some pulled lip of the tread on the leading edge of the tire. Considering I lost the rear end in 2 of the last 3 track days. I'm beginning to wonder if I'm having some rear grip issues from the setup of the rear shock. The rear tire is getting replaced before the next TD (supercorsa SC V1) and I am hoping to have the suspension setup at the start of the day. I'm wondering if I should do anything before then. I have the ohlins shock extended. I can't remember the number at the moment, I'll have to check my book, but I think it is around 6mm. The forks sit flush with top triple. Could that extra anti-squat be unloading the rear weight bias too much? I forgot to take pictures this morning. I'll update with some tonight when I get home. I've been running 30F/28R hot off the track.
