Caliper Cooler Kit for 996 Turbo or Carrera 4S with Larger 350 mm Rotors (not PCCB)

A popular upgrade to the 996 Carrera 4S and Turbo is larger diameter rotors – swapping out stock 330 mm rotors to larger 350 mm rotors like those on the 997 Turbo. This change provides better braking action and feel.
Rennkit™ has the solution: Cal*Cool™ brake caliper coolers. A quick modification that allows excess heat to dissipate much faster. Conductive and convective heat transfer quickly dissipates brake caliper heat while driving. When parked, conductive and radiative heat transfer continue to effectively remove heat from hot calipers. Track tested – all 4 corners remained below 370F:

Replacement brake disc for PFV Direct Drive V3
Ever since the disc brake was invented vibration and pulsation caused by thermal expansion has been a major issue giving rise to warped discs - until now?
PFC has released new V3 disc and hat technology. The advanced design features a patented attachment design that uses a retention ring that holds the hat and disc together.

The ring means no need for torque wrenches, and no hassle. The ability to change a disc quickly and efficiently saves time and effort. As well as being convenient, the new V3 technology is much lighter than previous designs, making it easier to put on and pull off, and making the vehicle lighter.

This V3 disc retention method is based on the use of a two-turn retaining ring, which is held in a groove in the hat that overlaps the disc flanges – effectively locking the disc to the hat.

● Exceptional manufacturing standards - Run out less than 0.0254mm, Thickness variation less than 0.00762mm. Surface finishes less than .7 microns.When used in conjunction with Z rated fast road/track day pads, component life and on track performance markedly improved over competitors pads.
