I used EBC greens on my E36 M3 for about a month and has warped my floating rotors twice!! I contacted HMS and EBC and they replace them with RED and with few others with same kind of problem it brought EBC rep to E36 M3 board and posted official warning on Greenstuffs. They are NOT compatible with hot temp rotors. That should include any car with M engine. PLease keep this in mind before you place your order okie?
