Put them to a real world test. Let me drive your car down the Dragon at real speed one time. If they are not burnt up into little plastic balls or scorched tin plates at the turn around, mile marker 11.5, will give you $100.00. Deal ?
Dave I feel you'd be taking one heck of a risk. I've observed your driving on the dragon & you need all the braking you can get.
Lol - I’m of the big brake group, not the covers. If I had some or if someone wanted to donate them, I would be happy to test. My preference would be Road Atlanta... 10 hot laps would show the difference. Granted if there was an actual difference, braking could get a little wonky. If I’m in town, I may be running the Champs race at Road A.. I’ll bet that car doesn’t have covers on it.. (or any of the other cars for that matter).. which to me ultimately answers the question. If they worked under hard conditions, racers would use them.
