ok i searched and didnt get an exact answer to this so, on the freeway will the car pick up faster because of the lighter flywheel or will it be just the same or slower ?

 

from what i know (me and my LIMITED knowledge) the car should pick up faster...if you have a flywheel that is too light, than you might have a problem launching from a dead start...
somebody jump in if i'm wrong...

 

bump?

 

it will hardly make a difference...you will notice a lil bit better pick up, but nothing to call up your friends about.
