Clutch Masters 725 Series Lightweight Flywheel for the K20 Honda Civic SI and Acura RSX 5/6 Speed
When upgrading or replacing your K20 Civic SI or RSX Clutch Masters 725 Series Clutch kits, a brand new lightweight flywheel is the perfect solution.
This flywheel will greatly reduce rotating mass and free up HP. Fully made in America and can only be paired with one of Clutch Masters 725 series clutch kits due to the proprietary sizing, will NOT fit OEM style clutch kits. 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 double checked for imperfections and tolerances, and is then ready to be paired with your 725 series clutch kits and ensure you put all the power directly to the ground.
All flywheels are SFI 1.2 Certified for use in motorsports.
**These Flywheels are compatible with the 5 Speed or 6 Speed variations of K20 Civic SI’s and RSX’s**
