The Highest Dry Boiling Point Racing Brake Fluid You Can Buy
CMS Performance RF1 fully synthetic Racing Brake Fluid is formulated to provide the highest 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 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.
So we did something about it. Manufactured in partnership with Orthene Chemicals, a British brake fluid supplier to professional race teams in Formula 1, WEC, and many other pro series, CMS Performance 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!
CMS Performance RF1 Racing Brake Fluid Specifications:
Typical dry boiling point: 622° F (328° C)
Typical wet boiling point: 399° F (204° C)
Exceeds DOT3 & DOT4 standards

A Note About Brake Fluid Boiling Points
DOT 4 brake fluid like RF1 is hygroscopic, meaning it attracts water over time sitting in your brake lines and reservoir. At high brake temperatures, this water can boil in your car's brake lines, causing the fluid in the lines to become compressible. That's what you feel when you experience brake fade. This is why the "wet" (aged fluid) boiling point of any brake fluid is substantially lower than the "dry" (brand new fluid) boiling point.
Since time is the enemy of brake fluid performance, the best practice is to replace your racing brake fluid before each track event/weekend. At a minimum, flush it with new fluid at least every three months if you're consistently racing and/or driving at track days. A couple bottles of fluid will flush most sports cars or race cars. It ends up being pretty 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.

The Girodisc system is a direct replacement for the OE disc, no modifications are necessary. 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 bias is maintained as well as your ABS efficiency. The Girodisc front rotors are approx. 13.0 lbs vs. 15.3 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 Girodisc rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The disc 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 forcing cool air through the disc.
The disc and hat have a floating mount system, which utilizes 12 high-strength alloy steel drive pins, manufactured in the US by Girodisc and cadmium plated for long-lasting corrosion resistance. These pins take the loads from braking while maintaining the axial and radial float between the hat and disc. They are secured by class 12.9 cap screws and hardened washers.
In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise springs on the disc side, allowing the iron disc to expand as it heats up while eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the brake pads.
Once the Girodisc system is in place, you simply replace the cast iron discs when needed. This reduces cost over time by allowing you to re-use the aluminum central hats.

D1-171 Girodisc Front Rotor Ring Replacements
$600.00
REPLACEMENT ROTOR RINGS ONLY. INCLUDES NEW INSTALLATION HARDWARE. DOES NOT INCLUDE ALUMINUM HATS.
Thunderhill is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most Girodisc products the same or next business day to ensure we meet your delivery deadline.
These Girodisc replacement rotor rings are direct replacements for the iron discs on your Girodisc two-piece rotors, and no modifications are necessary. New cap screws and washers are included with these replacement rotors. We do not recommend re-using the old hardware.
The replacement rotor rings 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 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 ring-only replacement to minimize replacement costs and deliver outstanding performance and cooling.
