Would installing lighter wheels, improve the fuel economy somewhat, due to less weight to push around? I will be losing about 8.5 lbs per corner replacing my style 42's with BBS RK.

TIA,

Yes, you're supposed to get a better fuel mileage with lighter wheels. I'm not sure if it will be noticeable though.

Filling up my E39 w/ 93 octane costs me $40 dollars a week. If I can even save just $1, I'd be giddy.
