Last night I installed my spohn torque arm, I have the bmr angle finder. I was going for a -2.

with the torque arm bolted on I put the angle finder on the flat spot of it where it attaches to the rear end and had +2. (#2 on the right side of the top mark)

I measured the angle of the driveshaft and had -4
(#4 on the left side of the top mark)

so wouldn't that give me the -2 angle I want?
I have a nasty vibration!

My wife says that if you subtract a negative it becomes positive????? help!!!!

did I mention that while trying out the torque arm I outran the cops and hid from them? haha It was like the dukes of hazzard, fly <img border="0" alt="[Firebird]" title="" src="graemlins/formula.gif" /> past them, hide and watch them FLY past you!

 

Don't know but the wife could be right on that math stuff...But what we need is a down-word angle on the yoke of the rearend. This angle is best set at -2 (average best others differ) this way when the shock is transferred to the drive line the rear will sift up word and now be in a straight line with the driveshaft. (Someone correct me if I'm wrong) Just know this YOU WILL were out U joints driving around town like this. You very well could have a lot of vibration if you do you will introduce the ol knock retard into the big picture and loss power. Another thing If you have a drive shaft safety hoop look to make sure it is not against the exhaust pipe like mine was this gave some vibration also.
