Carbon Fiber DriveShaft?

bldg636 · 07-03-2013, 06:11 PM

I was reading that there are quite a few companies that offer full carbon driveshafts.... I wonder if its a worthwhile upgrade..... Less rotational mass=better power transfer to wheels...... Looks like you could pick one up for about $1500

The inertia required to spin our driveshaft is pretty low, it isn't like a wheel or a flywheel. It would be similar to trying to improve horsepower by reducing the weight of your brakes. I don't see any notable gains from what we already have.

You'd be surprised: Dyno testing light weight rotors?

Granted, this was an Evo with AWD, but with the CZP 2-piece front rotor kit saving ~8 pounds per front corner, I could see some potential speed increase. For the rear wheels, I think only Racingbrake rotors would work, but whatever.

Do front rotors/wheels really matter since its not part of the "true" drive train?

Spend your money on a lightweight clutch/flywheel instead. You will definitely feel that.
