FITS: DODGE VIPER (2003+) REPLACEMENT ROTOR DISCS ONLY, DOES NOT INCLUDE ALUMINUM HAT. Thunderhill 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. The GiroDisc replacement rotor system is a direct rotor disc replacement for the Giro Disc 2-piece hat and rotor and no modifications are necessary. 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 2-piece GiroDisc design allows for rotor only replacement to minimize replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.

Chillout Systems Pro Touring Sport Cooling Shirt (SFI Rated) The Chillout Systems Pro Touring Sport SFI-rated driver cooling shirt has 160 ft. of certified cooling veins structurally spread throughout the shirt Nomex material, covering three times more of the human torso than competing cooling shirts. Heat exhaustion can break your focus and cause you to make mistakes. The structured cooling vein design of Chillout Systems garments cool your core even at temperatures close to ambient (55o F optimum), cooling the whole body and boosting your mental focus. Systems using ice water are often too cold for efficient cooling, causing the capillaries just below the skin surface to close, slowing blood flow back to the core. Ice water systems can give the perception of cooling by changing the temperature of the skin without actually lowering your body temperature. This fire-rated cooling shirt is specifically designed to contour perfectly to your torso, simulating a second skin to minimize negative space between the cooling veins and your body. CONNECTORS Chillout Pro Touring shirts do not come standard with hose-end connectors. For use with a Chillout Systems cooler, you will need to add a Chillout Systems dual prong adapter. For use with a Coolshirt cooler, please add Coolshirt male connectors.
