All seriousness aside, according to the Road & Track Road Test Summary, braking results as follows (60 to 0 mph): smart fortwo - 130 ft; VW R32 - 134 ft; M-B C350 Sport - 135 ft. Yeah, there are cars that stop shorter than the smart, but with those two as benchmarks I'm happy with the stock brakes. If bigger brakes float your boat, have at it.
