Materials are properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity. ACT's Streetlite flywheels are preferred for street or drag racing. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.

Feel: Noticeably improved engine response and acceleration, OE to mild gear rattle
Recommendation: Recommended for street and race use
Had this flywheel installed with my new ACT clutch in my STI. The car revs much quicker now and there is no additional chatter.
Paired this up with act extreme duty , very happy. I can feel the difference in response. Definitely a recommended upgrade.
Have yet to install the flywheel but arived quickly and looks great. Will try to update review upon installation.
I have a built 2006 STI that had been running a stock flywheel.. After installation my car revs so much quicker, you can feel the relief of the motor without that heavy stocker, that being said is DOES chatter on slowdowns, it DOES loose centripetal force and slow up hills... but those small things compared to the increase response and ease of driving are hardy an issue. Great buy, Great place to buy from. Thanks IIR!
No CELs and my engine both revs up and loses RPM’s faster. It’s a bit chatty on decel with a SBC Stage 3 clutch, but that’s as expected for a lightweight flywheel. Make sure you use new OEM flywheel bolts and make sure you clean the surface of the flywheel with brake cleaner well before you mount the clutch and pressure plate.
