RENNKIT™ Braking Upgrades

  • Cal*Cool™ Brake Cooling Plates 

  • Girodisc 2-Piece Rotors

  • Brake Pads – Ferodo Racing / Performance Friction

RENKIT™ Cal*Cool™ Caliper Cooler Kit for 996 Turbo / Carrera 4S and 997 C2S / C4S with Larger 350 mm Rotors (not PCCB)

A popular upgrade to the 996 Carrera 4S and Turbo are larger diameter rotors by swapping out stock 330 mm rotors to larger 350 mm rotors like those on the 997 Turbo.  This change provides ultimate cooling, better braking action and feel.  Everything you need to move the caliper further out to accommodate the 350 mm rotor swap.

A known problem is brake calipers over-heat and cook the brake fluid during high speed track use:

 

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 Test #1 – Autobahn Country Club, Joliet, IL – 996 Turbo with Stage 1 tune, NASA HPDE advanced group; all 4 corners remained below 370F:

Track Test #2, The monster, Road America in Wisconsin –  996 Turbo with Stage 1 tune, PCA HPDE advanced run group.  Two days on track.  Added lower temperature Thermolabels to all 4 corners.  NEVER EXCEEDED 330F!

NEVER EVEN REACHED 330F!

From our customer Billy Browne:  “My 02tt is proof positive of your track statement. I added your Cal*Coolers… & she braked relentlessly without any surrender!”

Save your brakes!  Cal*Cool™ brake coolers are easily inserted between caliper and wheel hub carrier using provided bolts.  Far more stability, conduction and surface area than simple collars that others sell. Reduced brake vibration, fade and fatigue.  All hardware is included, along with easy to follow step by step illustrated instructions backed by the customer service that Rennkit™ is known for.  Come with 2 year limited warranty.
(NOT FOR CARS WITH STOCK 330 mm ROTORS or PCCB Ceramic brakes)

Why upgrade to Girodisc rotors on your high-performance Porsche 911?

  • Replaces current heavy 1-piece iron rotors with the lighter weight Girodisc 2-piece unit (Aluminum/Iron)
  • Reduces unsprung weight at each corner – more responsive suspension
  • For 996 Turbo and C4S; easily upgrade to larger diameter 350 mm rotors for better stopping force
  • Replace expensive PCCB ceramic rotors with less costly 2-piece aluminum/iron rotors, especially on the track.

The central hat is 6061-T6 aluminum.  The disc is a proprietary cast iron and machined start to finish by Girodisc.  Rotors utilizes a curved vane design, developed in racing to act as a centrifugal fan, forcing cooling air through the disc.

    

Drilled holes are not used as they tend to crack under heavy use such as at the track. The rotor and hat have a floating mount system, utilizing 8 or 10 high strength alloy steel drive pins, manufactured to Girodisc specifications, with cadmium plating for long lasting corrosion protection. The pins take the load from braking actions while maintaining axial and radial float between hat and disc. The pins are secured with grade 12 cap screws and hardened washers. To keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers. This allows the rotor to grow with heat expansion, but eliminates rattle and noise associated with floating rotors. This float allows the rotor to self center between the pads.

Bonus:  Once the Girodisc rotors are in place, simply replace the cast iron disc once worn below suggested limits.

We have the rebuild kit as well; iron rings with all hardware and instructions to replace the iron rotors.   CONTACT US for rings only pricing.

 


PADS

There are four compounds to choose from, Street/Track to full on Endurance Racing. Ferodo is currently a top choice at the track.

Ferodo DS UNO Compound

Ferodo Racing has made great strides in pad development over the past few years, and DS UNO is their latest offering. For those that enjoy the performance of the DS1.11 in club racing, HPDE, and time trials, but just want a more aggressive bite, the DS UNO is a great choice. It doesn’t wear quite as long as the DS1.11, but it does offer a higher overall mu once it reaches track temperatures.

Ferodo DS3.12 Compound

The DS3.12 is the latest evolution of Ferodo’s incredible DS line. Sports cars today have more of everything:  More horsepower, more aero, higher curb weight and stickier tires.  These attributes place great demands on the vehicle’s brake system.  The Ferodo DS3.12 is a modern pad compound designed to explicitly handle those demands. Ferodo Racing DS3.12 pad compound is proving to be a tremendous asset for Porsche drivers participating in club racing, HPDE, and time trials. The DS3.12 shows the flattest torque curve across the broadest temperature range we’ve ever tested. That means the brake pedal is going to feel exactly the same heading into every turn of every lap, providing tremendous consistency and repeatability. The DS3.12 has a higher mu than Ferodo’s other compounds, so not as much leg pressure is required to initiate the desired response. It is also unfadable, showing no drop in performance at any temperature. In dyno testing, the DS3.12 has shown superior wear rates to the other Ferodo compounds, while remaining kind to the discs. The DS3.12 pads are becoming the gold standard in comparison to other pad race compounds.

Ferodo DS1.11 Compound

The DS1.11 is one of Ferodo Racing’s latest endurance race pad offerings.  The DS1.11 is known for its extremely flat torque curve, which means that as temperatures go up, the response through the brake pedal remains consistent. The DS1.11 can be thrashed all day without having it burn up or fade, it’s easy on discs, and doesn’t have many of the judder or vibration issues that competing products have. If you want an extremely solid, all around race pad that will perform well and last longer, the DS1.11 is the perfect choice.

Ferodo DS2500 Compound

Although we always recommend using a dedicated race pad for the track, the DS2500 is one of the best hybrid street/track pads on the market. It features the moderately high bite and solid fade resistance of a track pad, with the relatively low dust and noise levels of a street pad. When used as a street pad, it may produce some squeal on certain vehicle platforms. During aggressive driving the DS2500 is known for its flat torque curve, which means as temperatures go up, the response through the brake pedal remains consistent. If you drive aggressively on the street, do some canyon runs, autoX, or HPDE track time, the DS2500 is a solid choice.

When used on higher HP, heavier cars (2,800 lbs+) at the track with race tires, pad wear rates tend to be higher than with Ferodo’s other pad compounds. Under these conditions, the Ferodo DS1.11 or DS UNO are recommended.

These highly recommended pads come in two compounds.  PFC is involved with numerous Sports Car events across the globe, including:
– IMSA
– Continental Tire Sportscar Challenge
– Porsche Cup Racing
– Pirelli World Challenge
…and many more.

08 Compound

Less aggressive bite and fade resistance than the 11 pad with better wear for track use.  Best when rotors are warmed up.  Many enthusiasts use this pad for the larger fronts and the 11 compound pad on the rears to slightly increase braking bias toward the rear’s smaller pads.
