The Performance Friction 378.066.61 & 378.066.62 V3 Disc Rotor is a direct 2-piece rotor replacement for the Porsche 997 GT3 Cup.

Compared to the 379-series rotors, the GT3 Cup Spec features a 378x32mm disc with a 60mm braking surface and is designed around the 7819 pad. The full race float design can be used with the factory caliper on both the street GT3 and the Cup, with no other parts or modifications necessary.

Kit includes everything needed (rotor, hat and hardware) for a single rotor replacement. Priced per rotor.

The V3 design features an all new retention ring that holds the hat and disc together without the need for traditional nuts & bolts. The simplified design also helps save weight and makes rotor replacement a breeze. The 2-turn retaining ring is held in a groove in the hat that overlaps the rotor flanges, effectively locking the rotor to the hat.

This item is for the pair, full rotor.

Fits 997 GT3 Cup. 380mm Outside Diameter. 32mm Thickness.
