i Did Fidanza 7.5 lb flywheel with Exedy sport clutch. Dude, trust me difference is night and day. the car doesnt slouch as much. off of first the car rockets thru the gears.

i raced a stock GSR last night. After the inital launch his car was slightly ahead of me in first, I matched them up and got up on him a bit in second, but then in third I took off!!. Look on his face was priceless at the next light!!.

also the car feels much lighter on its feet than it did before. For example if i got the car full of people (yes 4 additional passangers 3 of wich wear seatbelts) the car doesnt struggle as much going up steep hills with the ac on.

its worth every penny!!
