Description

The Ksport Supercomp Big Brake Kit represents the pinnacle of Ksport's brake upgrade technology, engineered to deliver unparalleled stopping power for your Audi S4 (2009-2013). This kit features oversized 8-piston calipers, 330mm slotted rotors, and larger brake pads for maximum performance. The calipers are constructed from a single billet of aircraft-grade aluminum, ensuring lightweight strength and corrosion resistance, while aluminum pistons enhance heat management. The floating two-piece rotor design allows for slight shifts, reducing brake drag and ensuring more even pad application for optimal performance. Included are SC5 Street Pads, which provide excellent braking in street and occasional track conditions, with reduced dust and noise compared to race pads. Additional features include CNC-machined carbon steel caliper brackets for direct OEM location fitment and D.O.T. compliant stainless steel braided brake lines, which eliminate line expansion under pressure for a quicker pedal response and firmer pedal feel. The rotors are available in either slotted or cross-drilled options, with slotted recommended for track use and cross-drilled for daily driving. It is important to note that Ksport Big Brake kits are built to order and typically require 4-6 weeks for production and delivery. Furthermore, Ksport Big Brake kits generally fit 2WD vehicles only, unless explicitly stated otherwise. Buyers are strongly encouraged to confirm fitment with their specific vehicle details before purchase.
