The triple disc is the best, its the lightest, I run mine with a 153 tooth flex plate and a stock starter, great if you dont get caught. Eddie

It's not only the weight deal but how small the clutch is. As the clutch unit gets smaller as to the crank center line the engine has a quicker response time or gains
RPM's quicker.On the other side when you lift off the gas the engine will shut down quicker.I know you can't use them but a Brinn or Burt setup has a very quick crank response because of the very little weight &
the small size of the crank hub.

you said you used a flexplate will that work with a manual trans. Or did you mean flywheel.

A 3 disk is a package unit, it has the disks and pressure plates and flywheel in one unit, it just needs a flexplate for the starter. It weighs 15lbs. The Quartermaster unit is 1 friction disk and the pressure plate an it weighs 11 pounds but you have to add the flywheel to that So add more than 14lbs for a light weight aluminum unit and you are over 25lbs and only if you find the aluminum flywheel. + you will have more $$$ in it.
Rotating acceleration is weight X diameter SQ, for example, 10 inch SQ is 100 X 10lbs = 1000. A 5 inch SQ = 25 X 15lbs = 375.
The example is for reference ONLY! It shows how a lighter assy might not be faster.

If a single disc will hold for you and is legal it is better.

It is lighter overall and cheaper to rebuild.

A single disc doesnt have the multiple metal plates in it so it doesnt rattle like a multi disc does, if your sneaking in a lw aftermarket clutch!!!!

I have two viper single discs for sale in the classifieds.

they weigh 8-9 lbs. one is 7 inch on is 7.25 both are beefed up with dual diaphragms and held with my 13-1 412 and 14-1 406s this year.
