The goal of bedding-in your brake pads and discs is to mate them together properly and prepare them for heavy use.  When prepared properly, or bed-in, your pads will transfer a thin layer of material to the disc face (transfer layer).  The pads in your caliper will then actually ride on that thin layer of pad material you’ve put down on the rotor, rather than rubbing directly on the iron rotor face.  A good transfer layer is going to give you superior brake pedal feel, less noise, superior pad wear, and lower the chances of cracking your discs. Important Notes- PLEASE READ! First, make sure you are on a closed course to perform a proper bed-in.  Do NOT perform the procedure on public roads.  You need a stretch of asphalt with long straights, good visibility, and no potential obstructions.  Make sure you are in a position to safely and repeatedly attain the necessary speeds to perform the bed-in procedure.  A controlled racetrack is the best place to perform this procedure.  AP Racing and Competition Motorsport in no way suggest or condone speeding on public roads or breaking the law in your car, nor do we take responsibility for any damage or injury that occurs as a result of using our product or these procedures.  You are performing the bed-in procedure at your own risk.  During these procedures, it’s critical that you never come to a complete stop with your foot on the brake pedal.  If you have brake ducts on your car, you may want to block them off to allow your brake system to heat up easily. The procedure outlined below is a generic procedure for most types of mild race pad.  Please check your pad manufacturer’s recommended bed-in procedure. Accelerate to approximately 60mph and then decelerate down to 5 mph.  If your car has ABS, you should try to hold the brakes at a point just before ABS intervention.  Once the car slows to 5mph, immediately accelerate back up to about 60mph, and brake again to roughly 5mph.  Repeat this series of stopping and accelerating 8 to 10 times.  Again, do not come to a complete stop with your foot on the brake pedal. Cool the brake system down by cruising at 45mph+ for 5 to 10 minutes. Visually inspect your discs.  They should be a blue/grey color (instead of shiny silver), and have an even layer of pad material across and around the entire rotor face. If the AP Racing rotors don’t have a layer of pad material on them, perform another series of stops in the manner outlined above.

A2-156 Girodisc 2pc REAR Brake Rotors (OEM PCCB) PORSCHE 991 TURBO & 981 CAYMAN GT4 OEM PCCB This Girodisc system is a 390mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for the OEM PCCB brakes. The A2-156 will bolt directly to your Porsche and work perfectly with your OEM calipers. There are two main reasons for replacing your PCCB: first, the Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the machined cast iron rotor rings are far more durable than the fragile OEM carbon-ceramic rotors. This is critical when you're swapping wheels on and off the car for track days or racing, because it's so easy to nick a carbon rotor and take a nice chunk out of it. When paired with the Girodisc A1-156 front rotors, your factory brake bias and ABS efficiency are maintained.  When used with Pagid or PFC performance brake pads, and Competition Motorsport RF1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum.  The disc is manufactured from cast iron which is constructed in the USA and is made to the same specification with the same material used by professional racing organizations.  The rotors curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.   The rotor and hat mount together through a floating mount system which utilizes eight to ten high strength alloy steel drive pins manufactured by Girodisc in the USA to our own specifications and are cadmium plated for corrosion resistance.  The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat.  The pins are secured by Grade 12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The two-piece Girodisc design allows for rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

A1-156 Girodisc Two-Piece 410mm Front Brake Rotors   This Girodisc system is a 410mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for your car's OEM PCCB brakes1. The Girodisc A1-156 will bolt directly to your Porsche and work perfectly with your OEM calipers. There are two main reasons for replacing your PCCB: first, Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the machined cast iron rotor rings are far more durable than the fragile PCCB rotors. This is critical when you're swapping wheels on-and-off the car for track days or racing. It's so easy to nick a carbon rotor and take a chunk out of it, rendering it useless. Pair these Girodisc rotors with Girodisc A2-156 rear rotors to maintain your factory brake bias and ABS efficiency. When used with Pagid or PFC performance brake pads, and CMS RF1 brake fluid, you have an excellent solution to easily cracked carbon-ceramic rotors. The central hat section of the Girodisc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.

Sold/priced per pair. 1 Note: you must use the same pad shape as that used on the Porsche 991/992 GT3/Turbo with factory iron rotors. The annulus (pad swept height) of these pads is smaller than that of the large PCCB pads.

Girodisc A2-155 Two Piece Floating Racing Brake Rotors These Rotors Fit The Following Cars (w/ OEM Steel Rotors): Porsche 981 Cayman GT4 Rear Porsche 718 Cayman GT4 Rear Porsche 991 Turbo/Turbo S Rear This Girodisc system upgrades your Porsche OEM rear brakes to 380mm two-piece steel discs and aluminum hats. This two-piece floating rotor design will bolt directly to your Porsche GT4 or Turbo and work flawlessly with the OEM calipers using the included machined aluminum spacers. Especially when paired with the Girodisc A1-066 front Porsche rotors , upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Much lighter than the OEM rotors, Girodisc rotors reduce rotational and unsprung mass giving you stronger braking and faster suspension response. Combined with Pagid or PFC racing brake pads and Competition Motorsport Performance RF1 racing brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked OEM Porsche rotors that result from high-performance driving. The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc. The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion.
