The mountuneMK3 Focus ST rear brake upgrade from mountuneis a premium solution for drivers looking to elevate their vehicle's braking efficiency. By integrating larger grooved rear discs originally developed for the MK3 Focus RS, this kit increases the disc diameter from 271mm to 302mm.

Engineered specifically for the MK3 Focus ST, this upgrade balances high-performance requirements with a refined aesthetic. The system utilises the original caliper to maintain reliable operation while providing a significant boost in stopping power and thermal management.
