For those worried about angles ...
01-98-5084-B EMPI OFF-ROAD T-2 CV JOINT ONLY, 100mm, EACH $ 46.95
^ Max angle of 25 degrees
01-87-9469-B EMPI 930 CV JOINT ONLY, 108mm, EACH $ 51.95
01-87-9469-K EMPI 930 CV JOINT & BOOT KIT, 108mm, EACH $ 75.95
^ Max angle of 21 degrees - made for 930, if something can be done to adapt to the 108mm O.D. since 944s use 100mm O.D., if I'm not wrong
Plus many more options here... http://www.dansperformanceparts.com/...susp%20IRS.htm
Just found the above link on thesamba.org or something similar. Just copying someone else's research here for reference.

just ordered a pair. I killed my passenger side axle the last track outing. Heard a bang then something that sounded like a woodpecker. Found almost every bolt on the transaxle side of both axles was loose or out completely. Axle itself appears intact so probably the inner cage of the CV is toast. This is a great find BTW

As an update I pulled both my axles last nite and inspected them to look for broken cages or wear. No obvious signs of problems and they articulated smoothly. The passenger transaxle side CV was almost bone dry though. I re-greased it and swapped the axles L to R to reverse the stress on the units. Went to the track today and my noise was gone for now

Hi, what's your thinking behind this?
(Back when I was crewing, our driveshafts were marked L and R so we couldn't fit them in the wrong side.)
My understanding is that driveshafts don't like stress reversals, it's usually considered best to keep them loaded the same way. Otherwise they fatigue more rapidly.
IIRC, Carroll Smith mentions this in "Engineer to Win".
Of course if CV's are more likely to fail than the shafts, that's another story!
Cheers,
Mike

well I got mine and tried to install them today (EMPI). Mine is an early offset 86 and they don't fit. They are maybe 1/4" too wide in the axle to clear the mounting cups. I can attach the outer CV joints to the wheelside but the length of the actual axle will not clear the cup on the transaxle. It is a smidge too wide.
