Cool. From this thread, wheel weights are

18" 23.2/24.9, say 23/25
19" 23.6/26.1, say 24/26

So, all up weights with PS2 are:

18": 47/52
19": 48/51

Yep. Pretty close. So, let's say for all practical purposes there is no weight savings whether you get BMW 18s or 19s. After-market wheels/tires would have to beat this to realize a weight savings. Pretty hard to do without spending big bucks (i.e. high quality forged wheels).


Cheers.
