A1-122 Girodisc Two-Piece 350mm Front Brake Rotors FITMENT: Porsche Carrera S 991.2 Porsche Carrera 4S 991.2 Porsche Carrera GTS 991.2 This Girodisc system is a direct replacement for OEM Porsche steel (cast iron) rotors1 with the use of the provided caliper spacers. The Girodisc rotors are slightly larger than the stock Porsche rotors at 350mm vs. 340mm, providing greater braking force and cooling capacity. The Girodisc front rotors are approximately 21.0 lbs. vs. 24.4 lbs. for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. The central hat section of the disc 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. The rotor and hat mount together through a floating mount system which utilizes ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their 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 disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance. Sold/priced per pair. 1 Note: this Girodisc kit does not fit Porsche models with factory PCCB brakes.

The Girodisc system is an upgrade to a 350mm two-piece steel rotor and aluminum hat combination, a direct replacement for the OEM PCCB brake discs. The two-piece floating disc will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance iron replacements, you can eliminate the risk of cracking or breaking your expensive PCCB rotors at the race track. When used with Pagid or PFC performance brake pads and Competition Motorsport RF1 racing brake fluid (also available from Competition Motorsport), you have an amazing solution to overheating, cracking rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured in the USA from cast iron, made to the same specification and with the same material used by professional racing organizations. The rotor's 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 8-10 high strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from braking 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 typically associated with floating rotors. The two-piece Girodisc design allows for rotor-ring only replacement to minimize future replacement costs. Priced per pair

CMS Performance RF1 DOT4 Racing Brake Fluid Real-Life High Boiling Point Without The Real High Price RF1 Racing Brake Fluid from CMS Performance is a fully-synthetic DOT4 brake fluid formulated to provide extraordinary performance under the most demanding high-temperature racing and track-day conditions. With a dry boiling point of 328º C (622º F), RF1 exceeds all DOT3 & DOT4 requirements and is compatible with all DOT 3, 4, and 5.1 fluids. (Not compatible with DOT5 or mineral-based brake fluids.) On the race track, brake systems operate at very high sustained temperatures, and there is perhaps no single safety system more important in racing than your brakes. No single part of that system is more critical than brake fluid. At CMS Performance, we got tired of (and a little nervous) using "racing" brake fluid at the race track that didn't live up to its claimed performance when things got hot. So we did something about it. Manufactured in partnership with Orthene, the brake fluid supplier to many teams in Formula 1, WEC, and other professional series, RF1 Racing Brake Fluid was formulated to maintain consistent viscosity, lubricity, and compressibility at the extreme system temperatures and line pressures found in racing and track days. The bottom line is this: you can spend more on brake fluid, but you can't buy higher-performance than RF1 Racing Brake Fluid. RF1 Racing Brake Fluid Details: Typical dry boiling point: 328º C (622º F) Typical wet boiling point: 204º C (399º F) Exceeds DOT3 & DOT4 standards Bottle size: 500 ml (16.9 fl oz) Click Here for Product MSDS Sheet A Word About Flushing Brake Fluid All brake fluid degrades over time (not mileage), attracting water as it ages, which, at high brake temperatures, can lead to fluid boil and brake fade or failure. That's why the "wet" (aged) boiling point of any brake fluid is substantially lower than the "dry" (new) boiling point. To maintain maximum braking performance, Competition Motorsport strongly suggests replacing your brake fluid before every track event, but at least every three months if you're consistently racing and/or driving at track days. It's cheap insurance against learning about brake fade the hard way!
