    I'll start by saying this is a hell of a product, but even better is the service by HARDmotion. I ordered my clutch and flywheel when my current clutch was starting to go a little sideways. Then while waiting to get it, it got VERY sideways, so I contacted them to ask if there was any way to speed things up. They shipped it out that day! Saved my car from breaking down for sure. Many thanks HARDmotion

    Excellent service, excellent product

    I got this flywheel along with the stage 1 clutch. I was told that it would be more difficult to drive in traffic but I find it the opposite. The quicker pick-up and better bite of the clutch actually makes it easier to drive!

    Very fast shipping, and great customer service. Also on to the product review. The fly wheel does it job very wheel it can handle abuse that's for sure. I have it in my 09 supercharged civic and performed very wheel and it dissipates heat very well making it very good for performace applications. It's also light so it lets you to shift faster. All around a great product great job!!!

    Literally took only one day to arrive, along with my clutch, went with the exedy stage 1, 08806. Definitely meant to be paired together. All legit stuff, got everything installed and what a wonderful difference. Drives better, grips better, so smooth. Super good service, they helped guide me through it all. Sometimes you just need help and these guys were willing to explain it all. Also saved me like $500 bucks, lol. Will be back! A++++++
