Buy 6+, Save $1 per bottle Buy 12+, Save $2 per bottle REDESIGNED BOTTLE, SAME TOP-OF-THE-LINE BRAKE FLUID Competition Motorsport RF1 fully synthetic Racing Brake Fluid is formulated to provide the highest, most reliable performance under racing and track-day conditions, where braking systems operate at very high sustained temperatures. RF1 exceeds all DOT 3 & 4 requirements and is compatible with all DOT 3, 4, and 5.1 fluids. (Not compatible with DOT5 or mineral-based brake fluids.) There is perhaps no single safety system more important in racing than brakes. And no single part of that system is more critical than brake fluid. At Competition Motorsport, we got tired of (and a little nervous) using "racing" brake fluid on the track that didn't live up to its claimed performance when things got heated. So we did something about it. Manufactured in partnership with the brake fluid supplier to many teams in Formula 1, WEC, and many other professional series, RF1 Racing Brake Fluid is formulated to maintain consistent viscosity, lubricity, and compressibility at extreme temperatures and line pressures found in racing, track days, and spirited driving. Bottom line: you can spend more money, but you can't buy higher-performing racing brake fluid!   SPECIFICATIONS: Typical dry boiling point: 622° F (328° C) Typical wet boiling point: 399° F (204° C) Exceeds DOT3 & DOT4 standards Individual 500 ml (16.7 oz.) bottles   Click Here for Product MSDS Sheet 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.

FITS PORSCHE 911 GT3/GT3RS/GT2RS (2014+) FRONT WITH STEEL BRAKES The Girodisc system is a direct replacement for the OE disc on the 991 GT3, GT3RS, and GT2RS with OEM iron rotors. No modifications are necessary, allows use of factory unmodified pads unlike most aftermarket solutions for this application. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight, high performance replacements -- as opposed to a big brake kit -- your factory brake bias and ABS efficiency are preserved.The central hat section of our rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The rotor is made from Girodisc's own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for long-lasting corrosion resistance. These pins take the load from braking while maintaining the axial and radial float between the hat and disc. The pins are secured by Class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion, eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the pads.Once the Girodisc system is in place, simply replace the cast iron rotor ring when needed.When used with Pagid or PFC racing brake pads and hi-temp RF1 racing brake fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.If your car same with OEM center lock wheels please select the center lock drive pin option.Sold/priced in pairs.
