In Reply to: did they say "why"? posted by steve on December 10, 1999 at 10:53:10:
They left me a voice mail indicating that I should d only upgrade to 17". 18" is not recommended by BMWNA. Also, they told me that they can send me a catalog with all the 17" wheels.
So, no explanation on why not to go with 18". I was actually impressed that they responded in 1 day after my email.
