Clutch Masters Steel Flywheel Honda Civic Si 2006-2011 | FW-037-SF

The Clutch Masters Lightweight Steel Flywheel is designed for Honda and Acura enthusiasts looking to improve engine response and clutch performance without sacrificing daily drivability. Built from precision CNC-machined steel, this flywheel offers the perfect balance between lightweight performance and street-friendly engagement characteristics.
