FWD cars use a fixed joint as opposed to a cross groove. Fixed joints can handle more angle, but no plunge. Cross groove can handle plunge, but not so much angle.

So for the most angle, fixed joints and slipper shaft is the best option.  And then there's that whole binding issue with the slipper shaft.   Anybody make one with linear bearings in a groove to help with that?  (think small dia cv that is really deep).

Really? I don't know why RCV stuck in my mind but my apologies to RCV for the confusion.

I thought the same thing, had to go back and read his build thread to get the correct company.

Yes, for most angle. You'll still burn them up if you run them constantly at high angle though. If you drove a FWD car at full lock as fast as you could for an extended period of time, the CVs would get very hot. They still work well for a large amount of droop travel.

The issues with a sliding spline are if you try to use too much. The more plunge you have, the more side force will be applied to the CVs. Roller splines will apply less for a given amount of plunge. K-Fab's are roller spline and were very pricey. Hence the frustration with the poor welds on such expensive parts.

My Formula Cross has Audi 100 outer CVs inside on both ends with a slip spline in the middle.

K-Fabs IMC units were like that. I believe the slip shafts were off the shelf GKN parts.
 

 
They have thier own set of problems.......

If you went with rear A-arms you would need little or no plunge. 
No one is running their 930 at 30 degrees, I mean one the buggy and it load are on your prob at like 20-22.  Yes 30 when you jump but not constant.  If a FWD fixed CV was good for like 40 degree max and you ride height with passengers was 30 you gain a few inches travel or could narrow up width without loss of travel.  Still best with A-arm.

We do have the fixed GKN 930 joints with upgrade internal components.  These come with a lifetime warranty.  We have them for sale at $185.00. 

Our midslip design is not ball spline based.  Its more of a convential driveline slip.  The midslip shaft runs 185.00.

So a complete setup for one side will be..
185.00 for midslip shaft
370.00 for 2 930 CV Joints
$555.00
