I went on ACT's site the other day and I saw this new flywheel called XACT flywheel that they are manufacturing soon. The reason that I thought this was good is because it gives great gains like most flywheels and it seems that they have figured out how to make the performance and keep good driveability. But at the moment it's only for a few cars. I emailed the guy and asked if he would ever make any for the 4th gen maximas and he said it would depend on the demand for the flywheel.

So here's the webpage http://www.advancedclutch.com/V3/mainframe.htm

just click on the picture of the flywheel.
and post what you guys think.
