Big brakes aren't just for big cars. The TTSPORT 5420 is engineered specifically to unleash the braking potential of compact cars, designed to fit behind 15" and 16" wheels. We craft each caliper from high-strength forged aluminum, making it significantly stronger and lighter than the mushy, cast-iron single-piston calipers that came on your car.
The result is a huge improvement in stopping power and a firm, responsive pedal that gives you total control. By reducing critical unsprung weight, the 5420 also sharpens your car's handling and makes it feel more agile. It’s the perfect, high-value first step into the world of performance braking.
The following data highlights the engineering behind the 5420's compact performance. Note the exceptionally low net weight for a tangible improvement in handling. This kit is exclusively available with our high-carbon steel rotors and comes standard with our M-01 street performance brake pads.
