So the ultimate setup would be a Lightened and fully balanced crankshaft, lightened pistons and rods, lighter harmonic balancer, light flywheel with a 5" clutch, CF driveshaft, 10lb wheels...
I'm sure you would notice a huge difference after all those mods
now, I'm assuming cv's are lighter than the heavy U-jointed halfshafts, but I have heard that U-joints have less friction, so either one is ok?
