Description

The Ksport Slimline Big Brake Kit offers a significant upgrade in stopping power for your BMW E46 3-Series (1999-2005 models 318, 320, 323, 325, 328). The calipers utilize an opposed-piston design for even brake pad wear and are equipped with high-temperature seals and titanium retainer clips. The kit includes two-piece rotors that offer lightweight, fade-free performance and effective grip. Center sections are crafted from 6061-T6 aircraft-grade aluminum for better heat dissipation. Cross-drilled rotors are recommended for daily driven vehicles as they run cooler, while slotted rotors are suggested for more track-focused use. Included with the kit are SC5 Street Pads, designed for optimal braking in street and occasional track conditions, offering reduced dust and noise. An upgrade to RCI Race Pads is available for extreme track use. The kit also features D.O.T. compliant stainless-steel braided brake lines for improved pedal response and a firmer feel. Calipers come in various colors, with premium finishes and custom options available at an additional charge. The system includes CNC machined carbon steel caliper brackets to ensure bolt-on installation to OEM locations. This product is made to order and comes with a 12-month limited warranty.
