Here are the wheels with Michelin Pilot Super Sport tires mounted - 225/45 and 245/40 on 17x8 front and rear.

Very tight to the front strut but 2mm clearance all the way until lock at which time they rub but I won't do any spacers at this point. No problems with the fender lips - already rolled in the front. Still room to go wider in the rear so I will continue to look for the elusive 9" barrels.
The centre caps that come with the Style 42 wheel won't work with the front axel spindle and grease cap so I'll pick up a set of Alpina style caps (that is what is on them in the photos) with BMW "spinner" centres.
