I'm wearing out that Addco calculator- good thing I don't have to pay for it!
I did some calculations for the other two setpoints. Both the center to forward and center to rearward either adds or subtracts about 40-45lb/in. I'm not sure I'll be able to tune something that finite. My rear Hotchkis bar also has 3 holes, currently setup on the middle. I used to run full tight with the smaller wheel/tire package, but loosened it with the current setup. I like having all this adjustability! Now I need to find a big parking lot for circles.
