600145 is an ACT XACT Streetlite flywheel, built for noticeably improved engine response and acceleration with OE to mild gear rattle. It starts from a heat-treated forging for strength and toughness, with an induction-hardened ring gear for maximum life. One-piece construction reduces the chance of failure and provides uniform, efficient heat transfer away from the clutch disc, eliminating warped inserts or loose ring gears. It is forged, CNC machined, and dynamically computer balanced for smooth high-RPM reliability, and is recommended for street and race use.

FAQ
What is the difference between a Streetlite and Prolite flywheel?
Streetlite is ACT's street-focused flywheel, giving noticeably improved response with OE to mild gear rattle and is recommended for street and race use. Prolite is a lighter option built for a more dramatic response gain but with more gear rattle, recommended mainly for race use.
Why is one-piece construction important on a flywheel?
One-piece construction removes the extra joints found in multi-piece flywheels, which lowers the chance of failure and lets heat transfer away from the clutch disc more evenly.
Does this flywheel need to be balanced after installation?
No, ACT CNC machines and dynamically computer balances every XACT flywheel at the factory for high-RPM reliability.
Is this flywheel suitable for daily street driving?
Yes, ACT recommends the Streetlite flywheel for both street and race use since it keeps gear rattle close to OE levels while still improving engine response.
