Competition Motorsport is an authorized dealer for Girodisc products and we are 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. This Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination as a direct replacement for the OEM brake discs.  The Girodisc floating rotors will bolt directly to your Mustang and work flawlessly with OEM calipers.  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 effectiveness and efficiency.  The Girodisc rotors are lighter than OEM pieces, resuutling in a reduction in rotational and unsprung weight (4 lbs per corner) allowing for quicker acceleration, stronger braking, and faster suspension response. When used with Pagid or PFC performance brake pads, and Competition Motorsport RF-1 brake fluid, you have the best possible 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 constructed in the USA, 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 ten 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 only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

GiroDisc "Magic Pads" are the solution to your squeaky, dusty, expensive factory replacement pads. They have lower dust than typical factory pads and much less than other performance pads. You won't be cleaning your wheels nearly as often! Additionally, they have great initial bite, something most less-expensive pads lack. But the real reason people like Magic Pads so much is they are the "silver bullet" to brake noise problems. Magic Pads are a semi-metallic composition that is easy on rotors and on your wallet. We recommend always replacing pads as a whole car set when switching compounds. All Magic Pads come with anti-noise shields pre-installed and included in the price.

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 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!
