REPLACEMENT ROTOR DISCS ONLY. INCLUDES NEW MOUNTING HARDWARE. DOES NOT INCLUDE ALUMINUM HAT. Discovery Parts 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 Girodisc two-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 two-piece Girodisc design allows for rotor only replacement to minimize 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. If you have any questions, give us a call at 888-748-7223. We're happy to help!

The Girodisc S/S or "street/strip" pads represent the ultimate in high performance brake pads. The semi-metallic compound maintains a consistent coefficient of friction from 0o to 1000o F, making them an ideal option for people who are looking for a dual-purpose pad that works really well on both the street and the race track. The formula has very little compressibility, ensuring a very firm pedal and immediate bite and making the S/S pads a favorite among autocrossers and drivers who demand the most out of their street cars. Inevitably, these will dust more than Girodisc Magic Pads, but with the Girodisc anti-noise shims that come on every set of pads they will not make any noise if they are bedded-in properly. We recommend always replacing pads as a whole car set when switching compounds. All S/S pads come with anti-noise shims pre-installed and included in the price.

AiM Sports KA 50 psi Boost/Vacuum (Absolute Pressure) Sensor This "absolute pressure" sensor is ideal for measuring vapor (gas) pressures, such as intake boost and crankcase pressure. The 50 psi pressure range is based on perfect vacuum (i.e., from 15 psi below atmospheric pressure to 35 psi above). This sensor is marked "0-50psiA" to differentiate it from the standard 0-50 psi sensor (marked "0-50psiSG"), which does not measure vacuum. KA pressure sensors are more robust than VDO-style pressure sensors, but they should still be isolated from engine heat and vibration whenever possible. Features 1/8" NPT male threads.Kart  The AiM KA 50 is compatible with these AiM products: MyChron5 MXL MXL 2 MXG MXS MXM EVO3 EVO4
