Help setting up Speedtech torque arm for more traction

[exwestracer]

Front torque arm mount center of pivot is 57 3/4" from center of rear axle and 5" off the ground. Waterpump center is 19" from ground. Hope that's close to cam center.

I'll admit I took a couple of shortcuts on this, just using the desktop calculator. At 57 3/4" out, you are approx. 53 1/2% of the 108 wheelbase (assuming it's stock). Using the classic calculation for neutral line, and your measurement of cam height for C/G, 100% A/S should be about 10 1/8" above the ground at that point. So you are looking at approx. 50% anti-squat with the TA mount at 5" above ground. As I said earlier, there isn't much to adjust on it, but it does kind of clarify why the car won't hit the rear tires very hard.

I'm a firm believer in the torque arm as an excellent all-around suspension design (my own build uses one), but it does have limitations, especially trying to fit the mount around an existing subframe and floorpan.
