Thanks for all the feedback, some real good advice given here. I'm not surprised by the difference in opinions. Like my OP stated I know of two co-workers with a stock set up(tahoe, expedition) on 22's and they have had no problems. However, are they really cognitive of how their brakes are working. Maybe, maybe not, that's why i wanted some more feedback. I know there is a thread i think in the performance section about a brake, and rotor upgrade for fairly cheap and everything is bolt on. I'm thinking of doing that upgrade after i get the wheels. Thanks again guys, this is what makes this forum great.
