A twin disc design can be used to increase surface area of the friction liner, or keep the surface area the same, but locate it more to the center of the clutch. That being said, our Sport 275 & Sport 350 clutch & flywheel have a lower moment of inertia (meaning it is more responsive and spins up and down faster) than the factory twin disc clutch & flywheel (and considerable more so than the factory dual-mass single disc clutch and flywheel used on 97-05 NSX). That being said, this is a fine balance - you don't want the clutch and flywheel to have such a moment of inertia that drivability and reliability suffers. I think our clutches are an excellent balance - sporty, yet very drivable - and are less expensive than the factory assemblies.
