Porsche PCCB to iron disc conversion/replacement with PFC V3 DD 390x32mm rotors. Save those expensive PCCB discs by switching to slotted steel discs from PFC. 390.075.63-64. Fits center-lock wheels and 5-lug.
The 390mm PFC V3 conversion system is a direct rear rotor replacement for Porsche 991 & 991.2 GT3/RS and GT2RS models originally equipped with PCCB brakes. These will bolt directly to the car and are designed to work with OEM (Yellow) PCCB calipers.
With V3 technology you can swap discs in seconds with a flat-head screwdriver, utilizing a patented snap/retainer ring design.
The PFC V3 390x32mm rear rotor weighs the same (23.5lbs) as the OEM Brembo 991 GT3 steel rotor while being 10mm larger in diameter and 2mm wider!
You must pair with the pad shape used on the 991 GT3/RS rear axle with iron rotors (Red Calipers). This rotor is not compatible with the OE PCCB pad shape. The annulus (pad swept height) of these V3 steel rotors is slightly smaller than the PCCB's to keep rotor weight low and allow for a larger selection of pads to choose from.
Compatible brake pad shapes/compounds we offer include:
PFC 11 / 332 Compounds- 77188.8.131.52 / 7727.332.18.44
Ferodo DSUNO(Z), DS2500(H), DS1.11(W), DS3.12(G) - FCP4665(Z),(H),(W),(G)
PFC V3 Direct Drive Rotor p/n:
Front Left: 390.075.63
Front Right: 390.075.64
Front Pair: 390.075.63-64
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.
Part of being able to brake later is having the confidence in the pedal to get the car stopped. PFC V3 rotors are a premium rotor 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
*Notice* Recommended to be used with PFC pads only to ensure other pads do not have pad-to-rotor hat clearance issues. Please call/chat with us before placing an order if using another brand of pad. We will just need to verify the pad geometry.
Please call or email with any fitment questions/concerns. 414-212-5679. We will ensure you get the correct rotor for your application.
