For those who have installed heavier dual disk clutches (heavier as in weight, not pressure from the springs), have you noticed any additional sluggishness off the line from normal street start (engaging the clutch 100% at under 2K rpm) before the car reaches boost around 3K rpm? And for those who have installed a lightweight flywheel and a single disk clutch, have you noticed the reverse?

Just curious and planning ahead.

Thanks.

 

I don't know that the overall weight of the setup plus their lighter flywheels makes that much of a difference, the bigger drivability issue from a standing start that you describe would be due to a lighter flywheel since its the mass of the flywheel (and the clutch assembly but mostly the flywheel) would be less and therefore be a little "Tricky" for lack of a better term.

Personally I think I would leave the stock flywheel (if possible) or something close to the weight of the stocker for that reason though..

Lighter flywheels really allow the engine to rev to speed quicker and makes down shifting and rev-matching in general alot easier because of less mass to rotate.
