Description
These are a pair of replacement rings for use with your 380x35mm Brembo or StopTech Big Brake Kit used top hats. These are 100% plug and play.
Since the middle of the pandemic we stopped being able to consistently find StopTech replacement rotor rings. After months of being on backorder we reached out to verify with GiroDisc that they had an application for our track friend's E90 M3 Trophy Kit AeroRotors. Sure enough they did.
The disc is made from GiroDisc's own proprietary cast iron, poured in the good ol' USA, and machined from start to finish in house at Girodisc. The rotor utilizes 48 curved vanes, developed in racing to act as a centrifugal pump to force cooling air through the disc. Includes new floating pin hardware.
Known good replacement for:
- StopTech 31.846.1101.99 and 31.846.1102.99.
