I never mentioned anything about the ground, because the ground doesn't matter. Put a taller tire on and keep the same ride height, means the pinion is higher in the car, because the car sits over the tire more........... And as far as a handle on pinion angle, my handle is plenty good, some others around here, I am not so sure.

And Quicktree, if you have to ask me what positive pinion angle is, why are you even IN this discussion.

And still.......NOT ONE GURU has answered the question. Which WAS, if the front joint is lower than rear joint, the trans points toward the ground(and since some are SO caught up in exact numbers, lets say 3* tail down), which means the shaft runs UPHILL to pinion, would you roll the pinion UP 3*, to maintain a parallel angles, even though that HAS to put the joint broken over the WRONG way(positive).......when we ALL KNOW, or at least SHOULD know, that on acceleration the pinion climbs MORE and will make that joint angle even MORE wrong............waiting on an answer

How about a picture. So according to some of you THIS would be considered CORRECT since the engine/trans and rear are on the same angle. Even though the rear joint angle is over center and going to get worse on accel.........OK, find me a chassis guy who would set a rear angle up like this on a race car, thinking that is good to go and I will be quiet. For further clarification, we will even say this is where it is under power. Now I was always taught, that you NEVER want the rear joint to go over center under power in a race car.........but apparently it seems all those people who say that are full of hooey......LOL!!!
