adjustable torque arm....pinion angle?
ok so i installed my bmr adjustable torque arm last night when it dawned upon me that i had no idea how to measure pinion angle. so what i did was put a jack under the rear-end in an effort to hold it in the same place as when the original arm was on there, and fit it from there.
now i realize that it will all change once the suspension is under load, but im wondering if i just be worried about my drivetrain because i keep hearing about pinion angle and how important it is for longevity. i drove it around all last night and the car feels good and had a few hard launchs and no problems.
so my question is: should i really worry about it considering i have absolutly no idea what it is set at? and is there any easy way for me to measure the angle, and should i measure with the suspension under load? i work at a shop so more than likely it will be on a lift. thank you for the help ahead of time guys!

Yes the suspension needs to be loaded. Do a search for pinion angle. There are a few different methods to measure it. Look for posts by Madman, most people prefer his method. I use the one from the Rossler website. I set mine at -1*. Some say to set it at -2*.

The suspension should be loaded and level because you need to measure the angle of the trans. tail shaft and the rear end yoke then find the difference between them to come up with a -2* at the rear end.
