Product Description

The Comp Clutch 2-645-STU Ultra Lightweight Steel Flywheel is a performance-enhancing upgrade engineered for 2001-2006 Mitsubishi Lancer Evolution VII, Evolution VIII, and Evolution IX vehicles equipped with a 2.0 L turbocharged engine and manual transmission. This forged steel flywheel reduces rotating mass significantly compared to factory units, allowing the engine to rev quicker and improving throttle response - ideal for street performance, track use, and rally builds.

Precision CNC machining and dynamic balancing ensure smooth operation and reliable performance under demanding conditions. The one-piece forged design also helps reduce the risk of ring gear separation and friction surface warpage, while the SFI certification meets safety standards for performance applications. Compatible with both stock and high-capacity clutch assemblies, the 2-645-STU flywheel is well-suited to enthusiasts seeking sharper engine response and more engaging driveline feel on modified or high-output Evo platforms.
