Re: Drive shaft U-joints (formerly, CV U-Joint)

Elon,
On the normal u-joint driveshaft, the angle at the rear end and at the 
transmission should be the same for good operation. (upward at the rear and 
downward at the front) The primary reason for the double cardin (constant 
velocity) drive shafts was  to allow a downward angle at both ends of the 
shaft which resulted in less or no driveshaft tunnel. I can see no advantage 
in a race car which usually has no, or very little angle at either end.
