    If you can find wheels that are strong enough, yet fairly light, you wont need to worry about it.. I would suspect OEM wheels weigh anywhere from 15-20lbs... If you want some bling bling 20in Chrome wheels id say youd be looking at 25+ lbs... Whenever you increase wheel weight by 10lbs, its similar to adding 40lbs of static mass to the car..... So if each wheel is 10lbs heavier, you have 4 wheels, thats like adding 160lbs of extra weight to the car... IE another person, give or take..

    the short answer is, if your brake system is in decent shape as is, i wouldnt worry about it. If oyu are concerned about it, get some new rotors and good pads, and then go from there.....
