Description

The calipers are precision-machined from a single piece of aircraft-grade aluminum, providing exceptional strength, light weight, and corrosion resistance. They feature aluminum pistons, which offer superior heat management compared to other materials, ensuring consistent performance. This rear big brake kit includes 304mm two-piece slotted rotors designed for effective heat dissipation and grip. It also comes with CNC-machined carbon steel caliper brackets that allow for a direct bolt-on installation to the OEM caliper bracket location, despite the larger caliper size. The included SC5 NAOC Ceramic brake pads are formulated for optimal performance on the street and during occasional track days. These pads offer a significant reduction in brake dust (over 50%) and noise compared to race pads, with an optimal operating temperature range of 194°F - 1022°F. D.O.T. compliant stainless-steel braided brake lines are standard, replacing stock rubber lines to prevent expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel. The kit offers customization options for caliper color, including standard finishes like Orange, Red, Black, and Yellow, with premium upgrades to Silver, Gold, Titanium, or Glassy/Hard Anodized colors. Rotors can be specified as either slotted or cross-drilled, with slotted recommended for track use and cross-drilled for daily drivers seeking cooler rotor temperatures. This kit is specifically designed for the Mercedes-Benz SLK models from 1997 to 2003, including variants like the SLK200, SLK230 Kompressor, and SLK320. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks.
