most important: 2nd event and no video?! we need vids of tires screeching and engine/exhaust noises.
i guess my comments would be:
34psi cold seems pretty high. i run 34 hot which is 24 cold..might be because different tires though but if your tires are wearing fine, its all good. I'm lazy to swap my wheels back to zcp for weeks after the event and my tires look flat when parked - hope i didn't create any flat spots
seat belt lock is not needed...i use OC3's method of...scoot and lean your seat way back, pull the belt down and tug it until it locks, then buckle up while still giving tension to keep it locked......keep the tension and put your seat back to your driving position and let go of belt, it should be tighter than a virgin
that r3 looks nice but near $1k for something you plan to use 1-2 times a year...i guess its nice to have nice toys though so can't blame you (besides the safety part).
