this -2 pinion angle when is this measured? standard ride height? and also i was wondering could you not just weld on all the 4 link bars while the leaf springs are still attached that way nothing would move and would be the same, or is something in the way while trying to do this?Before you do that you'll want to make sure the axle is centered from side to side. Especially on Mazdas where we need such high offset wheels to begin with. You don't want to end up being able to tuck on one side, and catching your wheel on the fenderlip on the other.
thats a good sugesstion droptsdime cuz i didnt even think of that. the more i read on this forum the more i realize that im talkin to alot of educated people with a great sense of logic and safety. keep up the great work everybody im learning alot.
sorry, I should have mentioned that. Level the trans (angle finder on the pan) and set the rear -2, or measure the angle on the pan that is NOT level, and make the pinion -2 from that (if trans is at 10, make pinion 8 )
