Paired this up with act extreme duty , very happy. I can feel the difference in response. Definitely a recommended upgrade.

Good Flywheel

Have yet to install the flywheel but arived quickly and looks great. Will try to update review upon installation.

Made a HUGE difference in response in my 2006 STI

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!

Works dandy in my 2017 WRX

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.

The perfect clutch and flywheel combo

Got this clutch combo the next day and all I can say.. Its beautiful how my car drives and holds power now. Thanks to Josh and his crew.. He made it happen... Great price, Great customer service and great number 1 place to go for parts. Thanks guys at import image racing. THANKS
