The difference in caliper weight is moot and can be made up by dropping a couple of gallons of gas in the tank. The larger and heavier rotor (compared the the stock B6) will make your car feel slower, and the steering heavier. Its essentially the same thing as adding on massive wheels and tires.

Im not sure of the weight of the stock rotors, but my 321mm Zimmerman rotors weight 19.x lbs!
