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.
Sold/priced per pair.

In addition to the track-day environment, RS14 has shown success in short- to medium-distance circuit racing as well as gravel and tarmac rallying.
The Pagid RSL 29 (Yellow) is the world-leading endurance brake pad used by most of the winning teams in motorsport. Although designed primarily for endurance racing, many competitors use this material successfully for sprint and short distance races also. RS29 has also found favor in the growing track day market due to the level of control, good cold performance, long life and low disc wear.
Pagid RSL 1 Compound:
Used in GT cars, touring cars and prototype endurance racing. Due to the high friction and good modulation, often used in sprint races as well. RSL 1 is a low metallic resin bonded material containing steel and aramid fibers with very high heat resistance. It maintains a constant friction level over a wide range of temperatures. Its reduced wear rate and disc friendliness make this material appropriate for endurance races.

CMS Performance
CMS Performance RF1 Racing Brake Fluid (500 ml)
from $36.00
CMS Performance RF1 DOT4 Racing Brake Fluid
Real Life 622º 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 622º F / 328º C, RF1 exceeds all DOT 3 & DOT 4 requirements and is compatible with all DOT 3, DOT 4, and DOT 5.1 fluids.
Note: RF1, like all DOT 4 brake fluids, is not compatible with DOT 5 silicone-based or any mineral-based brake fluids.
On the race track, there is perhaps no single safety system more important than your brakes. No single part of that system is more critical than brake fluid, given the extraordinarily high temperatures it operates under. 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. We found more than a few brands whose product was all hype and not high performance.
No Hype. All Performance. No Kidding.
So we did something about it. CMS Performance RF1 is manufactured in partnership with Orthene, maker of the also-excellent Halo P1 racing brake fluid and a brake fluid supplier to many racing teams in Formula 1, WEC, and other professional series. RF1 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 a lot more on brake fluid, but it's hard to find higher-performance than RF1 Racing Brake Fluid.
CMS Performance RF1 Racing Brake Fluid Details:
Manufacturer: CMS Performance
Manufacturer part no.: CMSRF1
Typical dry boiling point: 622º F / 328º C
Typical wet boiling point: 399º F / 204º C
Exceeds DOT 3 & DOT 4 standards

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!
