I have all these measurements just don’t know how to input them or what formula I need to figure my antisquat percentage.

1993 camaro customtorque arm suspension
-Torque arm length (center or rear end to from mounting hole) 47 1/2”
-torque arm front mount height 6 1/2”
-lca height at rear end 5”
-lca height at body 6 1/2”
-lca Angle 6.5 degrees
-lca length 18 1/4”
- cam shaft height 18”

my instant center point (where torque arm and lca intersect) is 12.75” of the ground and 27” in front of rear axle.

The IC of a torque arm car is where a vertical line through the torque arm mount and a line through the LCA intersect. So you're IC length is 47 1/2", height is probably 8 3/4". You'll need the front and rear weights to find a CG estimate, to be able to estimate the anti squat. My recommendation is to run the car an adjust from there. Your close enough to test. Don't get caught up in "Bob"s" car works at "these" numbers. Where a car needs to be is dependant on to many variables to just set it at X and say that's good. There is a sticky in this section on F-body suspension but it's been a while since I looked through it. There may be info there. And note that if your LCA have an 1 1/2" rise and are 18 1/4" long that is 4.7°
