i see that megan sells the 5x114.3 conversion. i'm a megan distributor so that would be the way to go

BUT... if I just went with the cheap spacer converters... what would that look like? i can never figure out the whole offset calculation thing. wheel is +40 spacer is 10mm so...? is that equivalent to a +30 wheel or +50 wheel? in either case, how would it look?
