I personally prefer the CenterForce dual friction clutch. Easy on the street with a near stock pedal pressure and plenty of bite for the track, even with your future supercharger.
You will need a new clutch cable and quadrant with any aftermarket heavy duty clutch as the stock quadrant will not be able to with stand the load. Aftermarket quadrants are manually adjustable which allows you to select pedal engagement. The down side is you have to adjust it occasionally, where as the stock quadrant is self adjusting.
Good luck and have fun!
