Default Wheel center cap on or off for track?

Manual states caps on at all times. But I see many at track have them off. I know it’s easier to see the locking pins with them off but how will it affect the longevity of the center locks? How about on wet tracks ?

I always put them on. Never had an issue, and prefer to keep dirt out.

Best Regards,
Dave

I agree. The two minutes that it takes to put the caps on is time well spent.

Was always told ON, to keep sand/dust off the center-lock system
Wheels never got hot enough to be afraid of melting the cap... It did happen with other cars in the past :-)

NNJR PCA 2018 technical inspection checklist specifically states "Center caps must be installed before car goes on track"

Off unless you like to buy new ones. At least on the 997.2 with CL they would pop off on track days. Maybe the new ones stay on better.

Our region requires 997 off due to them flying off while on track, but 991 CL caps stay put. I always remove to check the lock then replace them. A nice older gentleman with an beautiful silver RS parked next to us at Sebring in Feb. He complained about stripping his wheel splines at the track. He had just replaced them, went out first session, came in quickly with a drive problem, it happened again. Rear wheel was loose and he was lucky to not lose it. We took off the caps and someone had not locked them. Can happen on a car that goes from service to trailer to track.

Here is a tip, most of us have damaged our CL caps changing out the wheels. Save them and use them for the track and leave the new ones for the street.
