Mupeak Brake Caliper Technical Specs

Mupeak currently offers three series of brake calipers, RP (Racing Performance); SP (Sprint Performance); SPE(Sprint Performance E-Park).

Details are as follows:

RP (Racing Performance)

The Mupeak RP Series is perfect for drivers who prioritize track performance, time attack, or club racing, while still offering the flexibility for occasional street use. These calipers are specifically engineered for track-focused performance, featuring enhanced heat capacity and cooling efficiency, along with increased rigidity to withstand the demands of endurance racing and intense track conditions.

SP (Sprint Performance)

The Mupeak SP Series is designed not only to deliver an impressive big brake aesthetic but also to handle high-performance sprint driving on streets and twisty roads. It's also capable during occasional autocross events and track days. This series of calipers offers a low operating cost while providing the reliable braking performance needed for spirited driving.

SPE(Sprint Performance E-Park)

Nowadays, more and more cars are equipped with electronic parking brakes on the rear axle, making big brake upgrades more challenging. The Mupeak SPE calipers, based on the SP Series, are specifically designed to integrate seamlessly with OEM electronic parking brake motors. Unlike other solutions on the market that require separate brackets and extended wiring, the SPE calipers offer a simplified upgrade. SPE series primary purpose is to allow users to upgrade OEM small rear rotors and calipers while achieving a clean aesthetic and high-performance .
