(Warning, drive shaft is carbon fiber so take caution when working on or around the shaft not to cause damage to it!)
Here is a link to the RX8club with the pictures of the flywheel with the counterweight. Sorry for not getting that in the video

An install of the act clutch kit, and the prolite flywheel. I believe we got pretty much most of it on video. It helps to drain the fluid first, then after that go and secure the rear differential to keep it from moving too much. Be careful when taking out the PPF as to not hit the drive shaft. When assembling you might have to lift up on the transmission in order to get the PPF aligned properly. This is a little help for those that want to tackle this on their own.
Again, please be careful with the drive shaft for it is made of carbon fiber so wrap in towels to prevent scratching.
