Flywheel spec

[mattspyder]

I'm going to be taking my flywheel to a machine shop tomorrow and I need to know what spec to have them check for.
It's a act flywheel with a act 2100 clutch kit.

The flywheel is stepped (the height of the pressure plate mounting pads over the clutch pad surface) and should be cut on the clutch seating surface and pressure plate mounting surface the exact same amount if using a stock clutch. This will insure pressure plate finger travel will remain at the original level. If using an aftermarket clutch, use the step height recommended by the manufacturer. This is extremely important with CenterForce Dual Friction units.

Most aftermarket clutches these days are set up for the factory step, which is 0.610", +/- 0.002".

got the flywheel back from the machine shop, had them machine it to .610 he said when he got it, it was at .615
put everything back together, started it up and took it out of the garage, it runs alot better now. still a slight sluggish off the line but I can live with that.
