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.

High Performance Drilled and Slotted Brake Rotors For Mercedes AMG
This Girodisc floating iron rotor system is a direct replacement for your AMG front OEM rotors. No modifications to your car are necessary. The 360mm diameter rotors will bolt directly to your Mercedes AMG and work with the original calipers perfectly.
The Girodisc front rotors are approximately 23.6 lbs vs. 34.5 lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When upgrading your original brakes with lightweight high performance iron replacements, your factory bias is maintained as well as your ABS efficiency.
The central hat section of the Girodisc rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is drilled and slotted for incredible cooling, made from Girodisc's proprietary American-made cast iron and machined from start to finish in house at Girodisc. The disc utilizes a curved vane design, developed in racing to act as a centrifugal pump forcing cooling air through the disc.
The disc and hat are joined by a floating mount system using 12 high-strength alloy steel drive pins manufactured by Girodisc in the USA and cadmium plated for long-lasting corrosion resistance. The drive pins bear the braking load 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, allowing the rotor to grow with heat expansion while eliminating the rattle typically associated with floating rotors. A floating rotor will also self-center between the pads.
Once your Girodisc system is in place, you can simply replace the cast iron discs as needed.

Fits Mercedes E63 AMG
The GiroDisc system is an upgrade to a two-piece steel rotor and aluminum hat combination; it is a direct replacement for the OEM brake disc. The two-piece floating disc will bolt directly to your 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 brake bias is maintained as well as your ABS efficiency. GiroDisc rotors are lighter than OEM pieces. The reduction in rotational and unsprung mass (approx. eight pounds per corner!) allows for quicker acceleration and suspension response.
When used with GiroDisc Magic Pads for the street, Pagid or PFC racing brake pads for the track, and Thunderhill RF-1 brake fluid (all available from Thunderhill), 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.
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 as well to minimize future replacement costs and deliver outstanding performance and cooling.

Pagid
Pagid Racing Brake Pads No. 8081
from $547.61
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.
