You seem really naive or really stupid
No one in their right minds use race spec brake material on passenger cars, racing spec material requires roasting before any race, this is done on qualifying lap of race. Passenger cars require brakes to function immediately whether is -40c or +200c at the brakes
Your hard sell of racing and enginuyring wont sell here, best keep it to your shop for sheeple customers.
