Trw 17102235 Round brake discRef : TRW00347A / 17102235

TRW MST503 Brake Disc – designed for demanding roadsters, this ABE brake disc combines robustness and a refined finish for precise braking. The machined support surface limits vibrations and optimises the grip of the pads, while the inner ring made of anodised titanium grey aluminium ensures a lightweight floating mount that is resistant to thermal stress.

Laser machined for sharp edges and precise geometry, this TRW disc features a profile designed to evenly distribute temperature and reduce wear and the risk of pad glazing. Compatible with organic, sintered metal, or carbon-based pads, it is suitable for both road and track use. The RAC construction (non-deformable steel) limits deformation even under heavy loads.
