Performance Clutch & Flywheel Kit & Polyurethane Transmission Mount Set
ECS Performance Clutch and Flywheel Kit – Built for Precision and Power
Step up your BMW’s driving experience with the ECS Performance Clutch and Flywheel Kit, engineered for drivers who demand improved throttle response, stronger engagement, and seamless power delivery. Featuring a modified E34 M5 clutch setup paired with an expertly crafted single-mass flywheel, this kit is designed to enhance both the feel and performance of M5x and S5x engines with 5-speed transmissions.
The single-mass flywheel replaces the bulky, factory dual-mass version, significantly reducing rotational weight for quicker throttle response and sharper acceleration. This kit retains the robustness of the M5 clutch but ups the ante with a reinforced pressure plate and clutch disc, giving you not only increased power handling but also a highly responsive pedal feel for precision control.
Perfect for both clutch replacements and power upgrades, the ECS Performance Clutch and Flywheel Kit transforms your driving experience without sacrificing pedal feel or adding unwanted stiffness. Say goodbye to spongy or overly rigid aftermarket options—this setup strikes the balance that enthusiasts crave, giving you both reliability and satisfaction behind the wheel.

Polyurethane Transmission Mount Set - Street Performance
Your transmission mounts are the backbone of your drivetrain. Stock rubber mounts often degrade quickly, leading to excess movement, mis-shifts, and, in some cases, even chassis damage. ECS Tuning’s Street Performance Polyurethane Transmission Mount Set offers an upgraded solution built for street and track performance alike.
Constructed from high-quality polyurethane and 304 stainless steel, these mounts are crafted to withstand the demands of high-torque and forced-induction setups, minimizing deflection and giving you more direct power delivery. With a 70A durometer rating, these mounts offer the best of both worlds—stiff enough to handle aggressive driving but still comfortable for daily commutes. For track-focused builds, we also offer a stiffer 80A version (sold separately).
Key Features:
Improved Stability: Reduced transmission movement for fewer mis-shifts and over-revs Polyurethane Construction: Stronger than rubber, with excellent oil and water resistance Engaging Driving Experience: A more connected feel without excessive vibration Dual Options: Choose Street (70A) or Race (80A) to match your driving style Durable Design: Mechanical interlock feature for high-stress applications Pair your new clutch and flywheel kit with these premium mounts for an unparalleled driving experience. Plus, our DIY guide makes installation easy—ECS Tuning has you covered from start to finish!
