Looking for the perfect balance of braking performance and daily drivability? The TTSPORT 7640 is it. This mid-size 6-piston caliper is our most versatile front-axle upgrade, engineered to deliver a huge leap in stopping power and thermal capacity while maintaining refined street manners. Its lightweight two-piece forged construction reduces unsprung mass, sharpening your car's handling and steering response from the moment you bolt it on.
The staggered six-piston design provides a firm, linear pedal feel that gives you incredible control and confidence under braking. Built with track-day durability in mind, the 7640 features ventilated pistons and high-temperature seals to fight off brake fade, ensuring consistent performance whether you're carving up back roads or stuck in traffic. It's the ideal, high-value performance upgrade for a huge range of sedans, crossovers, and SUVs.
The following data highlights the engineering behind the 7640's versatile performance. Note the staggered piston diameters for smooth engagement and even pad wear, and the lightweight construction. Your kit comes standard with our M-01 street performance brake pads for the included high-carbon steel rotors.
