StopTech Sport Brake Pads (formerly 309 Series) are engineered to provide high-performance braking for street-driven vehicles and light track use. These pads utilize a high-temperature para-aramid composite formulation to maintain consistent friction levels and linear response across a wide temperature range. Lab-tested for low noise and low dust performance. The kit includes: 1x Front Axle Set of Brake Pads (4 pads total), Part Number: 309.11180. Features include scorched friction surfaces for improved bed-in and factory-style shims to eliminate vibration-induced noise.
