Carbon fiber driveshafts, diameter size is from 30mm--450mm. Length is any.
Lighter than steel or aluminum.
Three times torsional strength of steel.
Torsional spring rate allows better tire hook-up.
Torsional spring rate allows smoother shifting.
Less shock load to the differential.
Eliminates or dampens high speed vibrations.
Reduces transmission and differential breakage.
In road racing smoother shifting and better durability of transmission and differential have been reported.
Tested on Cobra's at 180 MPH on Dyno with no vibrations.
A much greater safety factor - carbon fiber will return to a fiber and not create shrapnel under the car, as would aluminum or steel shafts.
