TX4 Street Series Big Brake Kit – 4-Piston Calipers with Forged 6082-T6 Aluminum Components

Description

SET TX4 4-Piston Forged Street Brake Kit

Engineered for daily drivers who demand more. The SET TX4 is a precision-forged 4-piston brake caliper built from aerospace-grade 6082-T6 aluminium, designed to transform the braking performance of compact and small vehicles — starting from just 15-inch wheels.

Why Choose the TX4?

Factory brakes on most compact cars are a compromise. The TX4 eliminates that compromise with 61cm² of pad friction area, a next-generation design language engineered to resist deflection under hard braking, and ultra-low dust output that keeps your wheels clean for thousands of kilometres.
