Description

Built around a 4-piston, high performance powerhouse, these Wilwood GP310 billet aluminum calipers bring distinctive, bold styling. Stainless steel pistons are employed to reduce brake fade while resisting corrosion, and high-temperature piston seals are utilized to extend life, control retraction, and provide drag-free operation. Additional features include bright finish bleed screws and hardware, plus an exclusive anti-rattle pad clip. The included low-dust, low-noise brake pads are designed to operate in the widest range of temperatures and environments, utilizing Wilwood's industry-leading stainless steel rotor-compatible formulation.
