I'd say that's a lot of pinion angle for having plenty of sidewall. Anytime I put more than -1 degree in my buddies '02 stang with 600rwhp it will "leap frog" off the line and unload about 5' out. Thats with QA1 rears set around 4 clicks and 15 PSI in 275/50 radials.

Back when we were running 315/35/17's, it was another story. I ran as much as -3.5 then.
