Nice Escalade, great detail. I agree with everyone about the brakes but what you guys need to realize is that you are looking at the rear brakes, not the front. I'm not saying the brakes couldn't stand to be upgraded but if you look at the size of the tire, it's actually almost the exact same od of the stock tire. As far as more rotating mass, I'm not sure because I don't know what those aftermarket wheels weigh, but I'm willing to bet that they are close to the same as those super heavy stockers. I have an 04' Expedition with 22 inch wheels and didn't notice any difference in stopping performance from stock to now. I'd love to put a set of bad a** brakes on mine, but don't really want the hastle of having to take it all off when I go to sell it later on down the road. Surely a set of 15" rotors won't fit behind my stock 17" rims!
