SFI Certification – Why It Matters

Whether you're chasing lap times or elevating your daily driving experience, the ECS S54 Performance Clutch Kit & Lightweight Flywheel is the upgrade your BMW deserves.

Single Mass Flywheel Conversion:

Audible chatter from the transmission after installation is considered normal. As with most single mass flywheels, there is less dampening in the flywheel to reduce "gear noise." This chatter noise may be more present when the transmission fluid temperatures are hotter and may be intensified by other modifications. Most gearboxes will experience some chatter noise at hotter temperatures. Please be advised that this noise will disappear once the clutch pedal is depressed. This symptom may be lessened by adjusting transmission fluid weight, turning off electrical/driveline consumers (A/C, High Beams, ETC.), and by raising the RPM slightly.
