No modifications to your car are necessary. The 380mm diameter rotors will bolt directly to your BMW and work with the original blue calipers perfectly. By upgrading your BMW brakes with lightweight high-performance replacements, your factory bias is maintained as well as your ABS efficiency. 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 brake fluid (available from Competition Motorsport), 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. Sold/priced per pair.
