ACT 12-15 Civic Si HD/Perf Street Sprung Clutch Flywheel Kit Reviews

I used this to replace the clutch in my Honda Civic Si 2013. It performs great. This is advertised as a light flywheel but I could not find the flywheel's weight on the website. For Honda Civic Si's 2012-2015 if the flywheel is less than 15 pounds you will need to reflash the ECU or you will get miss fires. You will also get a check engine light which will indicate the issue. My original flywheel weighed 16 pounds and this one weighed 15. Meaning that you do not need to reflash the ECU. That would cost a few hundred dollars extra to do. I've been using this clutch in my car with no issues or check engine lights.

Installed this on my 9th gen si coupe and this is definitely a 10/10 product. There is little no clutch chatter at all and feels well balanced and is smooth like a cvt money well spent
