Could someone please verify that my pinion/driveline angle is setup correctly? All measurements are taken from the passenger side of the car.

The tailshaft of the trans is points down towards the rear of the car at 2.5*


The pinion points down towards the front of the car at 0.5* (which is 2* lower from parallel with the tailshaft)


Here is a drawing of what I am trying to describe.


Does this look like a good angle (car is a M6 with the MWC trans x-member mounted long torque arm), or should I make them closer to parallel?

Thanks!

 

Assuming you have rubber/polyurethane control arm bushings and such, yes this is perfect. If you are running rod ends, then 1* or less would be good. Your diagram is spot on BTW. A lot of people have trouble understanding pinion angle, but it looks like you got it down. Just a quick question, where did you put the angle finder for the tailshaft measurement?

 

LCA's should have factory 1LE bushings.

Here is where I measured the tailshaft angle, the yoke that comes out of the trans. Is that an acceptable place to measure? I made sure it wasn't hitting anything else that would skew the measurement.

 

Yes, that is good. I was just checking because I have seen people measure their angles from some interesting places (usually a rough casted non-parallel surface) so I wanted to make sure you got it on something that is truly accurate to the driveline angle.

 

Perfect, thanks!
