The TTSPORT 5430 Forged 4-Piston Brake Kit is a true performance upgrade designed to serve as a direct replacement for factory calipers, aiming to significantly enhance stopping power and pedal feel. Its lightweight forged aluminum alloy construction reduces unsprung mass, thereby optimizing handling and steering response.
Featuring a reinforced, asymmetrical caliper body, this forged 4-piston brake kit completely eliminates the caliper flex issues commonly associated with factory sliding calipers, ensuring a firm, responsive, and predictable pedal feel with every application of the brake pedal. The 5430 calipers are equipped with high-performance components—such as ventilated pistons and high-temperature seals—that effectively resist brake fade and deliver consistent, stable stopping power. For your daily-driven sedan, crossover, or compact SUV, this represents the smartest and most effective braking upgrade solution available.
The data below highlights the engineering excellence behind the 5430's exceptional performance; note, in particular, its staggered piston diameters, which ensure smooth engagement and uniform brake pad wear, while its lightweight construction significantly reduces unsprung mass. This kit is paired exclusively with our high-carbon steel brake discs and comes standard with our M-01 Street Performance brake pads.
