Clutch Masters Lightweight Flywheel for the K20 Honda Civic SI and Acura RSX 5/6 Speed
When upgrading your K20 Civic SI or RSX with one of Clutch Masters Clutch kits, or any OEM style clutch kit, a brand new lightweight flywheel is the perfect addition while changing out your old OEM clutch kit.
This flywheel will greatly reduce rotating mass and free up HP. Fully made in America and is best paired with one of Clutch Masters FX100 – FX500 clutch kits for optimal performance, or use with any OEM style clutch kit. Every Clutch Masters flywheel is proudly designed and manufactured in-house. Flywheels are first designed in CAD and are then precision CNC machined in house in one of their Haas CNC lathes out of 1045 steel billet cores. After machining, the flywheel is zero balanced to ensure it is evenly weighted on all sides and spins 100% true. The flywheel is then assembled by a Clutch Master Craftsman, double checked for imperfections and tolerances, and is then ready to be paired with your OEM clutch kit or one of Clutch Masters FX100-FX500 single disc clutch kits. For the aluminum version of the same flywheel see FW-037-AL.
All flywheels are SFI 1.2 Certified for use in motorsports.
**These Flywheels are dual drilled and compatible with the 5 Speed or 6 Speed variations of K20 Civic SI’s and RSX’s**
