Upgrade your stopping power with a Front & Rear Performance Brake Service Kit from ECS Tuning. When adding more horsepower to your vehicle, it is imperative that you have a way to slow that power down and bring it your vehicle to a stop. One way to do that is to upgrade your brake rotors and lines. Your factory brakes getting near the end of their service life? This is a great opportunity to replace and upgrade at the same time! ECS Tuning has assembled this kit to upgrade the braking on your vehicle using our own ECS 2-Piece Full Floating Cross-Drilled & Slotted Wave Rotors mated with the great EBC Yellow Stuff Brake Pads, a combination that will offer a dramatic upgrade to your stopping power.

Our engineers are constantly pushing the boundaries, developing innovative R&D solutions to problems often overlooked by the factory. From addressing minor annoyances to engineering fixes that can prevent catastrophic failures, our team dives deep to create effective upgrades. Many of these solutions involve replacing less durable plastic components with robust metal alternatives, ensuring lasting performance and peace of mind.

Like many Audi models, manual transmission-equipped B6/7 S4's came from the factory with dual-mass flywheels. While this design delivers excellent comfort, smooth gear changes, and minimal vibration, it also adds significant weight, tipping the scales at a hefty 26.5 lbs. For performance-oriented enthusiasts, the dual-mass flywheel is a hindrance, dulling engine response and overall driving engagement. With this flaw in mind, we set out to design a lightweight, performance-minded single-mass flywheel for B6/7 S4 enthusiasts! Our precision-engineered upgrade weighs in at only 18.9 lbs, a substantial weight reduction of 29%! This reduction translates to a dramatic improvement in throttle response and engine pep, allowing you to extract even more driving pleasure from your S4.

Take your braking to the next level with our Stage 4 Front Big Brake Kit, engineered for enthusiasts who demand maximum stopping power. This high-performance kit includes quality, race-inspired braking components, delivering track-ready performance and precision stopping directly to your vehicle. Each part is designed and tested in-house at ECS Tuning to ensure quality, reliability, and compatibility with your application. At the heart of our kit are massive ECS 18Z 6-piston front brake calipers, which provide exceptional clamping force for consistent, fade-free braking. These calipers work in tandem with large 2-piece floating rotors, which reduce stress on the rotor hat while allowing the friction surface to expand independently under heat. This floating design improves braking leverage and ensures that your rotors maintain optimal performance even under heavy, repeated stops on the street or track. Additionally, our proprietary rotors are cross-drilled and slotted, giving you the perfect balance of durability, performance, and cooling. The slotted surfaces provide improved bite and consistent stopping power, while the cross-drilled pattern allows heat and gases generated during braking to escape, reducing the risk of fade and extending rotor life. Complementing the rotors are ECS EP24 "Enthusiast Performance" brake pads, formulated to deliver aggressive stopping power, smooth engagement, and reliable performance in all conditions.
