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 Brake Pad Spreader This indispensable tool is used by race teams, shops, and enthusiasts alike who have high performance four- and six-piston calipers. The spreader is designed to spread brake pads and pistons in four- and six-piston calipers to facilitate quick replacement of pads and/or rotors in a shop or racing environment.No more screwdrivers, pliers, hammers, or C-clamps! This tool will retract the pistons evenly and all the way back into their bores with one squeeze of the levers. The Girodisc spreader was designed around popular four-piston and six-piston calipers from Brembo, AP Racing, Alcon, and other performance calipers in racing and road use. To help fit in any caliper, the amount of throw is adjustable.Insert the spreading plates one way for wider six-piston calipers, then turn the spreader 90o and use the plate sides for four-piston calipers.The Girodisc Pad Spreader is made from heavy-gauge steel and is powder-coated for durability. The slider is cadmium-plated, and nylon pivot bushings ensure smooth action. The Girodisc Pad Spreader will quickly become an invaluable tool for any race team, shop, or enthusiast who changes pads and rotors with any frequency.

PAGID 8031 The 8031 Pagid Racing Brake Pad is used on the rear of various Mercedes models. The 8031 Pagid Racing Brake Pad is only available in the RSL 19 compound. RSL 19 is a low metallic resin bonded material containing steel and aramid fibers. It maintains a constant friction level across a broad range of temperatures. The material features very good modulation and release characteristics.

RS 14: Outside the track day environment, RS14 has shown success in short- to medium-distance circuit racing as well as gravel and tarmac rallying. RS14 offers very low heat conductivity, resulting in lower caliper and brake fluid temperatures. RS14 offers consistent levels of performance and much longer life than competitors' products without excessive rotor wear, offering the driver supreme confidence. The PAGID RS14 (Black) is a high-friction-value ceramic compound with very good modulation, high fade resistance, low heat conductivity, and a good wear rate up to a constant temperature of 1,200°F (650°C). It's kind on rotors, with visible grooving but no tendency to crack them. RS14 is our most popular ceramic-based friction material. It will tolerate much higher working disc temperatures than PAGID RS4-2, extending fade resistance. RS14 is used as an OEM material and supplied as an upgraded track day pad by Lotus Motorsport. It has been shown to exhibit optimum levels of braking force, control and modulation on popular track-day cars such as the Lotus Elise and Caterham 7.  RSL 29: Designed primarily for endurance racing, due to consistent levels of performance and user friendliness many competitors use this material for sprint and short distance races also. RS29 has also found favor in the growing track-day market due to the high level of control, good cold performance, long life, and low rotor wear. The PAGID RS29 (Yellow) is the world-leading endurance brake pad used by most of the winning teams in motorsport.  Based on the RS14, a slight reduction of the friction value improves modulation and longevity. The friction value remains high enough for cars without power-assisted brake systems, ensuring low effort on the brake pedal. Constant temperatures up to 1,100°F (600°C) are possible. This combination of friction value, fading stability, and low wear rates on pads and rotors is unmatched. Due to its excellent release characteristics and controllability, PAGID endurance materials are also often used for sprint races. This material provides very good levels of performance and response at all temperature levels; only slight temperature inputs are required to bring the pad up to its optimum performance level. A favorite with endurance racers at events such as Le Mans, Daytona, Spa, Nurburgring, etc. Due to the exceptional pad life and very low wear on brake discs it has been possible to run 24 hours without a change of pads or discs. This has proved suitable for applications running very high disc temperatures.

REPLACEMENT ROTOR DISCS ONLY, DOES NOT INCLUDE ALUMINUM HAT. Discovery Parts is an authorized dealer for GiroDisc products. As one of the largest stocking dealers in the country, we ship most products same or next business day to ensure we meet your delivery deadline. The GiroDisc replacement rotor system is a direct rotor disc replacement for the Giro Disc two-piece hat and rotor and no modifications are necessary. 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 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 to minimize replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.

Fits C63 AMG (08-2011) The GiroDisc system is an upgrade to a two-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake disc. 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 replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Giro Disc rotors are lighter than OEM pieces. The reduction in rotational and unsprung weight (approx. 8 lbs) allows for quicker acceleration and suspension response. When used with GiroDisc Magid Pads on the street, Pagid or PFC racing pads on track, and Discovery Parts RF-1 brake fluid (all available from Discovery Parts), 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.
