Wheel Center caps

BTW, do you know how hot the wheel would have to get to expand enough for the caps to come off easily? I'm guessing it would be hundreds of degrees, so that isn't why the caps can fly off at the track. The reason is because of the extra vibration from running over alligator curbs while cornering hard. Combine that with old, loose caps, and ping! off they go.

If the caps are a little loose to start with, it would not take much expansion (and that would not require 100's of degrees of heat) to have them loose enough to pop out, especially considering the vibration you mentioned. I know that when I have changed wheels right after a track session, the wheels were f'in HOT

IIRC, our PCA club requires them to be removed for track events.
