Hello, I am wondering if anyone knows whether the new BMW OEM M wheels, number 303 (found on the new F02 7 series) will fit my 2008 750 LI that currently has the stock 20 inch sport package wheels? I contacted 2 bmw dealers and they have no idea?? Below are the specs, though I am not sure what the e25 or e41 means after the wheel sizes. Both wheels say they have the following, exactly: uses a PCD5x120 centre bore 72.5mm and M14x1.25 bolt thread The one I want: BMW M Wheel number 303 Front alloy wheels: 20x8.5" ET25 Wheel part number: BMW 36117841823 Rear alloy wheels: 20x10" ET41 Wheel part number: BMW 36117841824 My current OEM wheels data: BMW wheels number 149 Front alloy wheels: 20x9" ET24 Wheel part number: BMW 36116764863 Rear alloy wheels: 20x10" ET24 Wheel part number: BMW 36116764864
"ET" is the offset from center. It looks like the fronts are fine, being within a millimeter of one another (25mm vs. 24mm), although the ½" wider wheel may be a problem, but the M rears are 16mm more offset than your OE wheels. That means that the wheel will be 16mm closer to the inside than your originals. This may produce interference or it may not. I think you'd have to try on a set to see.
unless you really want the staggered rims, you could just buy 4 fronts, you wouldn't have to worry about the offset and you would also be able to rotate your tires properly
