Stock CV Joint Angle of Degree Articulation, Is More Better for a Stock Axle? Options

[914Sixer]

I went over to Blind Chicken Racing and looked up CV Joints 101. The 914 CV is a slightly modified Type 1 joint. Type 1 shows to have 12 degrees of articulation. Going to update to 911SC rear stubs and hubs requiring 100mm CV joints. Type 4, Thing 181, 924/944 are all 100mm with 22 degrees of travel. VW Bus and Vanagan are 100mm too but with 17 degrees of travel.

Bus CV joints are about 1/2 the price of 924/944 with 5 degrees more travel than the stock 914. Any reason they would not be more than heavy duty enough for the job?

I always go for the stock angle (or more).

When we began selling Type 1 CV's, we used the Meyle units. They did not fully extend. We've found the GKN/Loebro joints have the proper articulation and those are the only 914/Type 1 joints we sell now because of this.

Real world issue? Mark De Bernardi was pulling out of a grocery store parking into traffic. The lot apron caused the CV to hyper extend beyond the Meyle's angle as the torque was being applied to merge into traffic. His cage cracked, causing the CV to fail. He did a "lot" of research as to why and this is when we found the angles were not correct. So, that angle is important... the bus CV's should be more than adequate.
