Description
What is the difference between a lightweight flywheel and a stock flywheel?
Lightweight flywheels like the ACT XACT Streetlite reduce rotational mass, significantly improving engine response and acceleration over stock flywheels.
Is a lighter flywheel always better for my car?
Enhancing engine response and acceleration is a primary benefit of lighter flywheels for spirited street driving and track use.
ACT XACT Streetlite Flywheels for 2009-2016 BMW 135i/335i models achieve a 9/10 score for Street Performance and Engine Performance. Featuring a heat-treated forging for superior strength and induction-hardened ring gears for maximum life, these flywheels deliver razor-sharp engine response with confidence.
What Owners Say
Owners and enthusiasts consistently praise the ACT Streetlite Flywheel for delivering noticeably improved engine response and acceleration without compromising street drivability. The strategic weight removal from the flywheel's outer edge creates a lighter feel despite similar overall weight to stock, with drag racers particularly appreciating the enhanced durability over factory components. Drivers report smooth operation with no chatter or noise when paired with quality clutches, and many note more precise shifting characteristics. Some users mention the engagement feel can be more on/off compared to stock, requiring a brief adjustment period to master the engagement point. The Streetlite has earned strong credibility among performance enthusiasts as a reliable upgrade that balances street manners with measurable performance gains.
