Are you running the 225/45-17 BFG or B'stone? I've seen some chatter on Miata boards about people considering going to a shorter tire due to the extended 2nd gear redline. Have you considered this option?
Yes, 225/45/17. We touch redline in 2nd gear at many events here, often two or three times on a west lot course without enough time to jump to third gear, so we lack much incentive to go shorter on tire here. I understand that in many regions the events are tighter and slower so perhaps elsewhere the hole shot advantage will exist because they are not banging the limiter, but here that is not the case.
Our west lot BMW Club events are generally a lot faster than SCCA. With some of our cars we have intentionally gone shorter for their events because we know we will be in third gear anyway and yet not so fast that we run out of third gear, have used 225/40/17 with success at those events (not a CS car).
