Hi guys, in 2005 BMW offered a 17" sport wheel (style 138) with spokes
that start narrow at the hub and flair out at the rim.
My question is are those 17"x7.5" or 17"x8"?
Thanks,
Chris

I'm in the process or ordering a 08 550i sport and I want to swap the wheels for 07 M5s. My dealer said no chance, neign. Has anyone ever heard of anyone being able to switch wheels?

The 138's are 7.5"
