Probably look better on Dynamics than those Classics...

Not suitable for the X6. The X6 needs something more aggresive and the suspension acts weird on the X6, better lowered.

Probably look good with metallic body colors...

The Alpina wheels can look great even though they are a very old design. I think ever since BMW went to the flame surfacing route the designs have suited bigger, chunkier wheels especially on anything bigger than a 3 series.

Looks great!

Cleaning those spokes will be a pain in the rear...
