pinion angle

what is the max pinion angle you want to go running a quick change

I think it is more dependent on what type of rear suspension you have. A clamp car may need a specific angle for proper setup where a spring behind needs more. Then to dictate whether the quick change will hit the track is dependent on the style and strength of the pull bar or lift bar. Just my thought, perhaps you've got specific application info
