Castrol
Castrol React SRF Synthetic Racing Brake Fluid
$74.95
Castrol React SRF Racing Brake Fluid
Castrol React SRF Racing Brake Fluid is an ultra-high performance brake fluid popular with many of the highest performing auto racing teams around the world. The key to Castrol SRF brake fluid's superior performance is its silicon-ester technology. Not only is it less hygroscopic (i.e., it absorbs less water) than typical glycol-based brake fluids, Castrol SRF also reacts chemically with any absorbed water to further reduce its adverse effects on high-temperature braking performance. The result is an almost unheard of 518° F (270° C) wet boiling point -- more than 100° F higher than most other racing brake fluids!
Exceeds SAE 1703, ISO 4925, JIS K2233, FMVSS No. 116 DOT3 and DOT 4 specifications.
Note: Castrol SRF is not a silicone-based brake fluid (e.g., DOT 5) and is compatible with most factory brake systems and fluids. Always follow vehicle manufacturer's recommendations when adding brake fluid.
TYPICAL PROPERTIES:
Dry Boiling Point: 590°F (310°C)
Wet Boiling Point: 518°F (270°C)
Superior anti-vapor lock properties
One-liter (1000ml) bottle
Chillout Systems
Chillout Systems Carbon Fiber Air Duct Plenum
from $195.00
Chillout Systems Carbon Fiber Air Duct Plenum
Forcing fresh air to your cooler is the most efficient way to increase cooling performance and reduce amp draw from your electrical system. This plenum fits perfectly to the intake side of your Quantum Cooler, allowing much cooler air to be forced through the system via any four-inch duct (cooler, ducting, and intake scoop not included). A minimum 150 CFM blower (sold separately) should be used in conjunction with the plenum in order to cool properly.
This carbon fiber plenum attaches via automotive-grade adhesive tape, creating a firm seal to keep the cooler pressurized with incoming cool air. This forces cool air all the way through the system and back out the exhaust side of the cooler, the most efficient way to reach maximum cooling capacity.
Coupling the Chillout Systems Air Duct Plenum with your Quantum Cooler ensures no cool air is wasted, maximizing the effectiveness of the system.
Pagid
Pagid Racing Brake Pads No. 8127
from $174.20
Fitment: Miata 1.8 NB (spec Miata) - Front
Pad thickness: 14mm
RSL 29:
The PAGID RS29 (Yellow) is the world-leading endurance brake pad used by most of the winning teams in motorsport. The racing compound combines the outstanding wear rate of the RS19 with a slightly higher coefficient of friction and initial bite. Based on the RS14, A slight reduction of the friction value improves the modulation (controllability). Nevertheless, the friction value is enough for cars without power-assisted brake system and ensures comfortable low effort on the brake pedal. Constant temperatures up to 600°C (1,100°F) are possible. This combination of friction value, fading stability and low wear rates on pads and discs (rotors) is unmatched. Due to its excellent release characteristics and controllability PAGID endurance materials are also often used for sprint races.
Pagid RS29 with a very similar friction coefficient to RS19 with improvements in initial bite offering quicker response and slightly more temperature stable at the upper levels of the temperature range. Developments in raw material selection and compounding have resulted in improvements also in pedal feel and feedback, helping with modulation particularly on lighter applications.
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. Another favourite with endurance racers having won many classes at all major endurance 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. Able to withstand slightly higher disc temperatures than RS19, this has proved more suitable for applications running very high disc temperatures.
Although designed primarily for endurance racing, because of the consistent levels of performance and user friendliness many competitors use this material successfully for sprint and short distance races also. RS29 has also found favour in the growing track day market due to the level of control, good cold performance, long life and low disc wear.
RST 3:
RST 3 is a medium-high friction metal-ceramic compound containing steel fibers and is therefore the perfect complement of the RST product family. It captivates by its low heat conductivity.
RST 3 compound applications include rally tarmac and gravel, GT cars, Touring cars and prototype circuit racing, formula cars and club racing. RST Compound fits a wide range of applications due to it‘s combination of bite, friction and controllability.

Lifeline
Lifeline Heat Detection Cable - Protectowire 356F - 180C
from $40.99
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.

Girodisc
A1-179 Girodisc 2pc Front Brake Rotors (Audi 8S TTRS)
$1,100.00
FITMENT (FRONT):
Audi 8S TTRS (2014-Present)
Thunderhill is an authorized dealer for Girodisc products and we are one of the largest stocking dealers in the country. We ship most Girodisc systems the same or next business day to ensure we meet your delivery deadline.
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 22.0lbs vs. 27.4lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our 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 to force cooling air through the disc.The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by grade 12 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 which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.Once the Girodisc system is in place, simply replace the cast iron rotor when needed. Sold/priced per pair.
When used with Pagid 8081 pads and high-temp racing brake fluid, you have a truly amazing, race-proven solution to the fragile, ultra-expensive carbon-ceramic rotors on your McLaren.
