304mm Front Big Brake Kit

The Ksport Procomp 2 Piston Rear Big Brake Kit offers a significant upgrade in stopping power for your vehicle, designed to enhance performance under sustained high-heat conditions. The kit features a one-piece construction from aircraft-grade billet aluminum for calipers, ensuring lightweight strength and corrosion resistance. The aluminum pistons within the calipers provide superior heat resistance and reliable operation. Each kit includes two-piece, 304mm (12-inch) drilled rotors and DOT-compliant stainless-steel braided brake lines. These lines resist expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to standard rubber lines. The included NAOC Ceramic SC5 Street Pads are formulated for optimal braking performance during daily driving and occasional track use, offering reduced dust and noise while maintaining effectiveness within a broad temperature range (194°F - 1022°F). The two-piece rotor assembly reduces both rotating and unsprung weight. For daily driven vehicles, the drilled rotors are recommended as they tend to run cooler than slotted options, though slotted rotors are available for vehicles with more track use. This specific kit is designed for the Honda Civic Si EP3 models from 2004-2005 with a 5x114.3 bolt pattern. Please note that Ksport Big Brake kits are built to order and typically require a production and delivery lead time of 4-6 weeks. California Proposition 65 warning applies.
