I remember somebody posting before about installing a flywheel from Racing Beat, but I don't think it was the "official" RX-8 version. Either way, RB is now offering an RX-8 specific aluminum flywheel. Ordered mine today; did it online, cuz calling them from Iraq would be a minor pain in the ****, so I'm not sure about availability/waiting time to actually get the part. But, I'm pretty sure it'll be waiting for me when I get back, so it makes me no difference:D

 

let us know how that works out!
