[s-cars] Driveshaft: New or Rebuilt ?

[Wylie Bean]

I'm facing this soon as well.. i figured I'd get the parts and have it  
rebuilt by a local shop that specializes in rebuilding driveshafts in  
Winston-Salem.  I know the 034 CSB needs some tweaking but didnt realize it  
was something to avoid. If not it, then what if any suitable alternative is  
out there?

Two piece is better for long runs for harmonic reasons and stronger. A long  
one piece has to be very well balanced or it can self destruct especially  
when speeds go up (autobahn). Obviously they can be made plenty strong...  
See every american drag car ever for evidence ;-). Audi trans-am driveshafts  
were one piece as well, but that may have been a design constraint with them  
being carbon fiber.

with locked diffs so I'm sure this option is robust.  Never could figure out  
why Audi went with the two part design.
