Before half the forum chews me out, I apologize in advance if this has been covered elsewhere. I know it has generally been stated that aftermarket upper control arms are not necessary when using 5100s. What I am looking for is people's specific experiences with caster angle after setting 5100s at .85. With no front lift mine are currently maxed out at 3.7. The drive is significantly better at those settings. I am trying to see how much I will lose off that 3.7 if I get 5100s and set them at .85.
