This is the Ventilated Steel Brake Disc from Ultimate Racing. It is machined from anodized steel in black. Compatible with Mugen and Sworkz among others.
Thanks to the holes and grooves, we achieve a lower temperature in the assembly, resulting in reduced wear and a more consistent braking feel.
These grooves also lead to a significant weight saving. The brake discs from Ultimate weigh 30% less than the original ones from Mugen. This weight reduction in the rotational mass translates to faster acceleration and lower fuel consumption.
