Front wheels - 26mm additional interior clearance (inner lip farther from the body) and the outside of the wheels will be 14mm farther out
Rear wheels - 23mm additional interior clearance (inner lip farther from the body) and the outside of the wheels will be 11mm farther out

Based on these results, it seems that the wheels will fit. However, if I take the average of these two numbers as an approximation for the change in the center of mass for the wheel swap, it results in 20mm outward shift on the fronts and 17mm outward shift on the rears. Now I know plenty of people that have run 12mm and 15mm spacers on their E60 M5s with no adverse effects, but what are people's thoughts about pushing the wheels out 17mm to 20mm? Obviously it will impact handeling - but this is for my winter tire set when I will not be pushing the car as hard as I would on the summer wheels. Any thoughts about the additional stress on the suspension components and potential for damage?

Thanks again for any advice, comments or suggestions.
Sorry, I strongly advice NOT to use these wheels; One of my companies is an automotive aftermarket distribution company, we do more than 20000 wheels a year and winter is our specialty; The first speed threshold will sort out in wheels touch the outer side of your bodywork; If you do not mind for that OK .. you can do mount those wheels but than again keep in mind SNOW CHAINS ARE OUT of the question; for that reason most of our manufactures produce wheels with offset values lower than OEM, with high performance cars on the other hand, you have the keep in mind that the X-factor of the rims are more important due to bigger brakes! Therefore imho I wouldn't go for guess work ;-)
