Sounds like CYA to me. The main reason to go to a dual disc setup (with smaller diameters and a flexplate instead of a std dia. flywheel) is to reduce inertial mass....No point in keeping the same diameter (12") and going dual as that just increases the mass and kills performance. If done right a single plate set up will work for everything you could want on the street. I'd go with a sprung disc as it reduces the shock loads when shifting...makes driving a LOT easier. Badger
