My wife's Wolfsburg Edition (06) needs new pads on the rear wheels. I know it's recommended to get new rotors when replacing pads, but they feel smooth to the touch. We're tight for money, so if I go to a mechanic and give him high quality pads to slap on, can I get by, or will I need new rotors in 10,000 miles? Is refinishing a better option (if it's not too expensive)? Also, do good brake pads really make a difference, and can anyone recommend any brands that aren't crazy expensive?
