The more roll resistance you have, the less static negative camber you'll need.

When I ran the 245's I had 500F, then changed to 750F, both with RM sway bars. And if I recall correctly, I only had -2º in the front until I chopped my stock upper control arms to get -3º.

Now that I have the 900F and 275's, I only run -2.5º with SPC adjustable control arms.
