Um ... no, not quite. His is a 2007 M45 Sport. So the offset needs to be near 47 to 50mm to work out well, I would think! With wide rims in the rear, like a 9.5" (which I have no idea if it will work!), the needed offset would be probably about 45mm for a good fit.
I suggest working with a good local tire/wheel dealer to get fitment advice. Can also try calling Tire Rack!
