get the approval of the wheel and weight police in the forum or of those who never have anything nice to say about anything. Your stock brakes will be fine with larger wheels. Just check your pads and rotors like you did before. As far as upgraded rotors with stock calipers, I'd check out Stillen's web site to learn about some options and compare the prices and options for larger rotors, better pads and stainless steel brake lines with those of the forum's sponsors. As far as your wheels are concerned, I hope the bolt pattern is correct. If so, you should be fine with the +45 offset. Good luck. Don't let the nay sayers discourage you. It's your car and your money!!
