Do you have or planning to use a power adder??? If not, why do you want a puck disc?? I have a CM stg. 4 in my SVTF and can say, if you want "bite" that is what you need. But it isn't great in a daily driver. If you don't have FI or nitrous and have a real need more holding capacity, the extra "bite" isn't worth the loss of driveability. Stop and go driving sucks!
As far as a aftermarket disc and stock pressure Plate/Flywheel it should work. I think that the SVT CM stg 1,3,4 use the stock pressure plate. All the aftermarket clutches will work with the stock flywheel.
