When you put the pedal to the metal, you're looking for one thing to happen: Response. We're not talking slow, mushy, eventually get there, high-RPM response. We're talking crisp, immediate, power to the wheel response. What is one of the biggest things to steal this response time right out from underneath you? Drivetrain mounts.

ECS Tuning engineered the perfect solution for your S4 - Introducing our new Rear Differential Mount Inserts. Our engineers have given you the best of everything; Excellent performance, unmatched ride quality, and a simple, easy installation.

Complete Kit Features include:

• Significant reduction in rear differential movement
• Billet & black anodized 6061-T6 washers and inserts for durability and corrosion resistance.
• Polyurethane differential carrier insert to reduce drivetrain deflection while keeping noise vibrations associated with such modification to a minimum
• Increased drivetrain rigidity and response
• Long-term testing performed on multiple vehicles for real-world qualification

It Makes The Diff.
