Up to a certain size (18" for this test vehicle), you'll reach diminishing returns for both 0-60 time and handling. IMO, the peak for an F10 is 20" before reaching diminishing returns on overall performance and ride quality. Still, 21s look amazing. Just expect to pay more for tires, get more bent wheels, harsher ride, and more rubbin.
The difference in weight on the same forged wheels may 2-3lbs as you go up in size, but when it's spinning at 100mph those 2-3lbs add up (imagine hanging onto a Mary-Go-Round). It's rotational unsprung weight.

Really, how much is an M5 Brake conversion? I like them better than BBK anyways.
Also, the F01 and F07 have thicker profile than the F10, so going 21" is the same as going 20" on a F10... what do you think?
And btw, forged wheels are less like to bend, and I've heard the ride isn't affected that badly...
