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.

  • Max Stroke: 10mm
  • Pressure Build Time: 45ms
  • Seal Temperature Rating: 180°C
  • Pad Thickness: 17mm
  • Pad Friction Area: 61cm²

Small cars and compact vehicles seeking a significant braking upgrade without requiring large wheels. Popular fitments include hot hatches, compact sedans, and lightweight sports cars running 15–18 inch wheels.
