I'm sure there's a big improvement in ride and handling. And while losing 34lbs in rotating mass (tires+ wheels) plus stickier tires should be bring some improvement in 0-60mph times, 4.8 to 4.4 sec seems a bit extreme. Some of this difference may well be due to their initial 0-60 time for the car on stock wheels and tires being a bit on the slow side, slower than others had reported.
I think MT was using BMW's quoted 0-60 time. Like you mentioned, with just different wheels and tires a 0.4 sec 0-60 drop is wishful thinking.
