  • Porsche 991 pccb Brake Replacement Option

    1. Replace to RB-ST rotors - Designed and built by RB (Discs made by Surface Transforms).

    These RB CCM rotors are made with continuous carbon fibers known to perform better and last longer than pccb's (Brembo's chopped fibers)

    In stock.

    2. Switch to complete RB CCB system like GTR track racers - Designed and built by RB (Discs made by Brembo, same as ZR1/Z28).

    You will run your brake like ZR1/Z28 owners for low cost (~1/4 of Porsche dealers') in disc and pad replacement. The calipers and complete system are designed and built by RB. Calipers are built for track duty and functionality with open top for super easy brake pad change w/o removing the calipers like OE.

    Same system as we built for David Donohue on his 991 Turbo and Cup cars

    In stock

    3. Convert to Iron Rotors - RB was the first brake company offers light weight two piece iron rotors for 991. We offer more CCB to Iron conversion than all competitions combined.

    RB iron discs are well defined by our decades' expertise in metallurgy and casting technology, they can outlast other brands in durability and performance.

    In Stock
    4. Switch to complete RB Iron System
    This package replaces OE calipers while retaining the use of pccb size iron rotors which means you can use ZR1/Z28 brake pads in replacement.

    In Stock.

    Components for those kits are in stock, ready to build and ship.

    As you can see we offer two types of Carbon Ceramic rotors - ST and Brembo, and two kind of rotor materials - CCM and Iron, so our presentation and opinion are based on objective data and facts, without marketing gimmicks like others.

    We offer more options than above all are detailed in our website, so if you are looking for the true value, and unbiased opinion for your brake replacement & upgrade. Our in-depth knowledge in Porsche brake shall make a difference towards your next brake investment.

    Which one would you recommend out of those two types of Carbon Ceramic rotors btw, Racingbrake? And why. I'm kind of torn and I can't decide.

      CCM rotors built with Brembo discs (ZR1/Z28) are made of chopped (short) fibers which, due to its material & construction, is more prone to chip and breakage.

      The other type of discs are made with continuous (long) fibers, which are made by ST and now RB discs.

      RB CCB disc is designed with angle vanes for more efficient cooling, and is the most advanced design and refined finish in modern CCM brake technology.

      Difference in vane design:

      Traditional Straight Vane Design (Brembo & ST): Rotor are non-directional (Left and right are the same, less efficient in cooling)

      Angle Vane Design (RacingBrake): Rotors are directional (More efficient in cooling air circulation and can keep braking temperature lower)

      Difference in finish:

            Just packed an order for a Porsche 991 GT3 customer (Red calipers- Iron 380x34 / 380x30mm) upgrading to Pccb size rotors (410x36 / 390x32mm).
            Discs are made by ST (Surface Transforms) and built with RB hats and hardware.

            Kit includes all caliper spaces & longer caliper bolts, stainless steel brake lines (replaces OE rubber and hard lines) for a complete bolt on installation.
