Well i ordered some -12's with ridge grapplers. Hopefully that wasn't a mistake. I was on the fence between the +0 and -12. I have bilsteins set at 2.8 and 3/4" spacer in the rear. I have flares that are about 2 3/8" past the current sidewall. I don't like mine out too far. again, hopefully didn't make a mistake going -12. thanks for the info.
