Speedtec Trailing Arm Question-anti squat and trailing arms

[cpd004]

The install instructions for the Speedtech TA set up trailing arms suggest adjusting them as close to parallel as possible. For me that is the 3rd hole from bottom on the rear axle mounts which has them roughly .02 degrees sloping up toward the axle. In other words, they are lower at the front spring pocket.



The instructions further say lowering the rear so it slopes downward at the axle increases anti-squat which increases traction. One hole down would make the arms well over a degree slope down at the axle. My understanding is this would increase roll oversteer making the car feel darty.

This is primarily a street driven car above all else.

Interested in thoughts on leaving it vs lowering the arm at the axle for primarily as predictable a street driver as possible.
