Can someone tell me if ACT Flywheels are any good? Comparable to Racing Beat and Mazdaspeed? I did a search and I can't seem to find any threads about ACT Flywheels; I know they make nice clutches, but anyone have any experiences using ACT Flywheels?

They offer two types of Flywheels:
StreetLite ~ 13.9lbs (flywheel only)
ProLite ~ 9.9lbs (flywheel only)

I'm not sure how heavy the counter weight weighs. The price is also pretty reasonable, cheaper than RB and MS

Your feedback is highly appreciated :D

The MS flywheel is 6.92kg or 15.3lb
Counteweight is 1.65kg or 3.6lb, flywheel only is 5.3kg or 11,8lb

I think its the best...

No one else use or know of ACT Flywheels? Help =)

I couldn't find the info or price for the RX8 on their website.
However, I have noticed that mazdamotorsports.com offers the 9lb ACT flywheel for the RX8 to racers. I believe it was around $270.
I'd also like to know if anyone has any experience with this flywheel.
