3 link holes on rearend

[MNBmod]

I have the 3-hole mounts on the rearend. Currently have trailing arm in the bottom hole farthest from the rearend housing. What difference would it make to move the trailing arm into the middle or top hole closer to the housing. i've heard something about more drive????

More angle the bar has, the more drive you have on that side, also you will get more rear steer.
