These Brembo HP2 front brake pads are specified for GT STI front fitment with BM4 backing and use the RE10 endurance compound. Intended as a direct-fit replacement for the listed Brembo-equipped front calipers, the RE10 compound emphasizes endurance characteristics for repeated use where the OEM pad is being replaced by an RE10-specified friction material.
