Not having ever raced, the ” rotor cooling rings "was a new subject for me:
" Rotor cooling rings (provided at the time of vehicle delivery in a clear plastic bag) are recommended
for track use (driving without the rotor cooling rings may result in brake pedal fade). Do not leave them installed after a track event, as this may cause corrosion with long-term use. Installation instructions are included with the rings and can be found in section 9-7 of the Owner’s Manual. "
