PFC V3 Direct Drive Rotors for Porsche 997 GT3 Cup - Front

Porsche PFC V3 DD 997 Cup rotors. Improve longevity and performance over your stock rotors by switching to slotted steel discs from PFC. A great OEM steel rotor upgrade or replacement with V3 technology. 378mm & 379mm rotors.

378mm Full Rotor Assemblies: 378.066.61-62 (Includes Friction Disc/Rotor Hat/Snap Ring)

379mm Full Rotor Assemblies: 379.067.63-64 (Includes Friction Disc/Rotor Hat/Snap Ring)

If purchasing Replacement Friction rings only, be sure your race hat is a V3 (snap ring design). Your current setup should not have mounting bolts. It is recommended for racing applications that full assemblies are purchased instead of only replacement friction rings.

Fitment Notes:

997 Cup 378x32mm Front & 348x29mm Rear- For 997 GT3 Cup cars with 378x32mm Front Discs (p/n 378.066.61-62) w/7819 pad shapes use 348.075.61-62 rear replacement discs. (No Rear parking brake, race only).

997 Cup 379x34mm Front & 373x29mm Rear- For 997 GT3 Cup cars with 379x34mm Front Discs (p/n 379.067.63-64) w/ 0991 pad shapes and 373x29mm Rear discs use rear disc assemblies with p/n 373.076.63-64

These PFC V3 discs are a direct front rotor replacement for Porsche 997 Cup Gen 1 & 2 models. This replaces the V2 discs that use bolts to mount the friction rings to the hats- the V3 system now uses a snap ring design for easy removal/install of new friction rings. These will bolt directly to the car and are designed to work with OEM Race braking systems.

PFC brake rotors are the absolute best rotors on the market. Years of testing and development went into the ultimate 2-piece floating rotor - PFC's V3 system.

In road racing, a lot of passing is done under braking and a lot of time can be gained in the braking zones. Part of being able to brake later is having the confidence in the pedal to get the car stopped. PFC V3 rotors are premium rotors and provide the performance, durability, and longevity to turn consistent fade-free laps.

PFC Rotor castings go through intense heat cycles where the castings actually get pre-warped on purpose. The warped disc then goes through the final machining process, virtually eliminating any potential for warping on your car.

PFC has put a lot of engineering effort into designing and testing its rotors. It shows as these rotors can be found on a ton of open-wheel cars running in the US, including IndyCars along with numerous Porsche and BMW track and race cars. More and more people are switching to PFC rotors for these ease of install/removal, performance, and outright cost-effectiveness. They simply outperform OEM and other competitors' rotors.

With their innovative Snap-ring design, rotors can be replaced in seconds.

Other Benefits Include:

• Reduced Unsprung Weight
• Reduced Thermal Distortion and Warping
• Runout of less than 0.0005" and 0.0002" thickness variation reduces vibration
• Reduced Heat Transfer to Hub Assembly
• Reduced Drag
• Reusable Hat Assembly (V3 not compatible with V2)
• Longer Life / Lower Cost Per Lap
• Reduced Weight Due to No Hardware (Only Snap Ring Required)
• No Rattle for Applications using Snap Ring
