Anybody running these 8.5 x 17 wheels (et 13) on an M5 with stock suspension? Looks like they might be the wheels on Ted's (ex-Mel's) car. Was thinking about 235/45/17 on these wheels all the way around, but am not sure about the offset... (FYI, Bekker's running a special on them this month....) Any input would be appreciated. Thanks.
