A: The short answer is NO.  The longer answer is we highly recommend not running center caps in your wheels while racing.  For the most part this really holds true for those who are road racing, or experiencing longer duration racing which would cause a build up of heat.  Many of our center caps are produced in plastic with a metal locking ring.  If you run these types of caps on track, once they heat up from transfer of heat from the heavy braking, they will become unsecured from the wheels.   This loss of cap is not a valid warranty claim (especially in the off-road racing use).   **If you’re participating through the NASA program, this is explained in the program paperwork you completed and we generally do not include center caps in your orders. **

With all of this said, most of our Flow Formed wheels come with metal caps which are secured onto the wheel with allen screws.  These caps, when properly installed, will not come lose with heat.  We still recommend that you remove center caps before racing.  Your local track or tech may even recommend this to you.
