DESCRIPTION
Upgrade the braking performance of your 09-15 Cadillac CTS-V 2nd Gen with Girodisc 2-piece Brake Rotors A1-239.
The Girodisc system is a direct replacement for the OE disc. No modifications are necessary. The disc bolts directly to the car and works with OE calipers perfectly. By upgrading to lightweight, high-performance replacements instead of a big brake kit, your factory brake bias and ABS efficiency are maintained.
The central hat section of the rotor is made from strictly U.S.-sourced 6061-T6 aircraft specification aluminum. The disc is made from proprietary cast iron, poured in the USA and machined entirely in-house at Girodisc. The rotor features a curved vane design, developed in racing, that acts as a centrifugal pump to force cooling air through the disc.
The rotor and hat feature a floating mount system with 12 high-strength alloy steel drive pins, manufactured in the USA and cadmium-plated for long-lasting corrosion resistance. These pins handle braking loads while maintaining axial and radial float between the hat and disc. The pins are secured with class 12.9 cap screws and hardened washers. Anti-noise spring washers on the rotor side allow thermal expansion while eliminating rattle, and the floating design enables the rotor to self-center between the pads.
Once the Girodisc system is installed, simply replace the cast iron rotor when needed.
