A1-156 Girodisc Two-Piece 410mm Front Brake Rotors FITMENT: Porsche 911 Carrera Turbo (991), Front Porsche Cayman GT4 (981), Front 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. 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: 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.

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!

Girodisc Titanium Brake Pad Shields FITMENTS: Porsche 991, 992, GT4 (Front) The problem of brake fluid boiling is caused by braking heat transferring from the rotors and pads directly into the fluid through the caliper pistons. When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible, of course, so brake pedal pressure compresses this air instead of pushing brake fluid and moving the caliper pistons. The brake pedal goes to the floor. Production street cars tend to suffer from this on track days because they don't have the extensive cooling ducts and exotic brake materials found on race cars. Race-only brake calipers generally come with titanium caliper pistons for one reason: titanium has very low thermal conductivity, which means it's bad at transferring heat. That's good if you're trying to keep your brake fluid from boiling. Here's a comparison of materials and their relative thermal conductivity ratings in Watts per meter-Kelvin (lower is better): Titanium 6AL-4V = 6.7 W/mK Steel = 52 W/mK Aluminum = 130 W/mK Most fixed calipers use aluminum pistons which are, unfortunately, excellent at transferring braking heat to your brake fluid. Our solution is to place Girodisc's thin titanium shims between each brake pad and the caliper pistons. This helps prevent braking heat from transferring into the pistons and, thus, into the fluid. For cars that are going to see hard driving or multiple track days, these shims are affordable protection against losing your brake pedal at the worst possible time, making your track day very expensive. Water-jet cut to exact size, so there's no cutting, grinding, or swearing involved. Price is per axle (four shims)
