A1-159 Girodisc Two-Piece 394mm Front Brake Rotors
FITMENT:
- McLaren 570S, Front
- McLaren 650S, Front
This Girodisc system for the McLaren 650S or 570S is a direct replacement for the OEM McLaren carbon ceramic front rotors1. It is an upgrade to a two-piece steel rotor and aluminum hat combination. These two-piece floating rotors will bolt directly to the car and work with your OEM calipers perfectly. By upgrading your brakes with these lightweight, high-performance replacements (as opposed to a big brake kit), your factory brake bias is maintained, along with your ABS efficiency.
When used with the proper brake pads1 and high-temperature racing brake fluid, these Girodisc replacement rotors give you an excellent, race-proven solution to the fragile and expensive carbon-ceramic OEM rotors on your McLaren.
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.
1 Note: These Girodisc rotors have a different annulus (pad swept area) than the OEM carbon-ceramic rotors, in order to maintain their light weight. A brake pad with an annulus of 66mm or less must be used with these Girodisc rotors.
We recommend the Pagid 8081 racing brake pads in either RS29 (endurance racing) or RS14 (sprint racing) compound.
If there's another specific pad and/or compound you're after please, contact us at (844) 438-7244 and we'll get you what you need!
