Sorry for being a bit nerdy but i know the answer to this one
a standard propshaft uj,s normally accepted working angle is 15 degrees
so a propshaft with two joints is normally recommended to work at up to 30 degrees.
so your 30mm offset is well within nomally accepted limits.
There are specials that allow more angle at extra low revs but then torque
starts doing massively strange things and extra large support bearings are needed and then it gets really extra nerdy..
but the simple answer is 30degrees in a car drivetrain is normally acceptable
cheers les g
seem to remember there is a variable somewhere that the maximum angle decreases as maximum revs increase ,but too throw in a googly i seem to remember that lifespan and rating of a joint is based on a continuous rpm figure
