how do i set the pinion angle on bmr torque arm?

i have an bmr adjustable torque arm. it came with a guage to adjust the pinion angle. i want to adjust it negative one degree, do i put it 1 to to the right of the zero or to the left, when it is magneticallly held upside down on the torque arm? thanks

i would like to know to

From BMR's website

Support vehicle under rear axle to load the suspension for pinion angle adjustment. Once suspension is loaded, attach the provided angle finder on the bottom of the rear end torque arm mounting plate and record the reading. Now place the angle finder on the driveshaft and record the reading. Subtract one angle from the other, this is your pinion angle. This angle is considered negative when the pinion points downward. It is best to start with 0 degrees pinion angle and adjust accordingly based on the cars launch characteristics and parts combination. As a rule of thumb, most automatics typically respond best to a -1 to -2 degree pinion angle while manual equipped cars respond best to a -2 to -3 degree pinion angle.

so do u have to lift the front and back or can u haveteh back in the air with the axle loaded??

You just need to have the weight of the car on the rear axle, it doesn't matter if the front end is on the ground.
