Race Technologies RE10 Brake Pad - 3434.17.RE10
$749.00
RACE TECHNOLOGIES RACING BRAKE PADS
RT RE10 COMPOUND1:
RE10 is the ultimate endurance race compound, offering a balance of excellent stopping power, low thermal conductivity, and extremely low pad and rotor wear. Utilizing the latest friction material technology, Race Technologies RE10 offers consistent performance in the most demanding environments.
Typical Applications: Professional Endurance Racing, Club Racing, and HPDE on high braking demand platforms.
RACING PAD NOTES:
Running a "racing use only" pad on the street could produce excessive noise and dust.
Rotor wear could be accelerated if driven at consistently cold temperatures or used in the incorrect temperature range.
Racing pads are designed to work in specific temperature ranges so it's important to choose the right compound for the environment the vehicle will be used in.
Pad compounds are tested on a brake dynamometer over repeated brake applications to test the materials in a controlled environment. Real-world wear rates and temperatures will be influenced by car setup, grip levels, track layout and other variables.
Note 1: "RE" denotes a "race only" pad.
Lifeline Heat Detection Cable - Protectowire 356F - 180C
from $98.99
Heat Detection Cable Protectowire 356oF / 180oC
Priced by the Meter
Protectowire is an electrical circuit containing heat-sensitive materials. When the outer covering melts, the wires will make contact and complete the circuit, activating the fire system. This can be a critical extra safety feature especially if the driver becomes incapacitated in an accident.
MOUNTING:
Mount along the ceiling of the cabin using an "S-pattern".
Some additional wiring may be required between the Protectowire and your system's electrical trigger.
Use care to not crimp or crease the outer sheath and create a weak spot.
Keep away from heat sources including the engine compartment, transmission, differential, exhaust, direct sunlight, or hot surfaces.
Keep away from any sharp edges that could cut or cause an abrasion on the sheathing.
An inline plug can be used to disconnect the sensor cable during storage, transport, etc.
The cable we sell is set to trigger at 356 F (180 C).Currently, Protectowire is only compatible with Lifeline electric systems.

A1-162 Girodisc 2pc Front Brake Rotors for Shelby GT350/GT350R (2015+)

A1-162 Girodisc 2pc Front Brake Rotors for Shelby GT350/GT350R (2015+)
FITMENT: Ford Shelby GT350/GT350R (2015+)
This Girodisc system for the Ford Shelby GT350 and GT350R is a direct replacement for the OEM front brake rotors; no modifications are necessary. The rotors will bolt directly to your Shelby and work flawlessly with the OEM calipers. By upgrading your brakes with lightweight, high performance two-piece floating rotors (as opposed to a big brake kit) your factory dialed-in brake bias is maintained as well as your ABS effectiveness and efficiency. Together with our customers, we have thousands of track miles on Girodisc rotors on every conceivable car. They are the go-to rotor for any of our track-day and race-car builds.
Girodisc two-piece floating rotors are lighter than OEM brake rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response.
When used with Pagid or PFC performance brake pads and CMS RF-1 racing brake fluid (available from ), you have an amazing solution to overheating, cracking and warping rotors.
The central hat section of each Girodisc 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 disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance.

1 Note: These Girodisc rotors have a different annulus (pad swept area) than the OEM CCM rotors, to maintain their light weight. A brake pad with an annulus of 66mm or less must be used with these Girodisc rotors. We recommend using the Cobalt C7 Z07 racing brake pads with this system.

PFC 11 Compound
A new generation sprint and medium distance friction: the ultimate in control with superior disc conditioning. Developed from 01 compound with improved bite, modulation, and release characteristics. It is ultra smooth and developed to reduce wheel locking at the end of braking while giving more cold and hot bite than the endurance oriented 08 compound. Brake with confidence; brake with ultimate control and modulation.
PFC 08 Compound
One of PFC's most popular compounds which came to fame in Endurance Sportscar and GT racing due to its performance in applications where smooth initial bite is a must. PFC08 has a slight friction rise with temperature, excellent release and modulation characteristics. Despite its considerable performance, 08 has the lowest wear rate of all PFC compounds and can easily match the wear characteristics of the other competitors' materials but with much higher bite and consistent performance across a broad temperature range.
