I have been wanting to upgrade my wheels for a good while now and seeing that I need new tires soon, I been looking around at my options. I really like the looks of a 20" wheel on an e60 and Im willing to deal with a little less ride comfort.
That being said... My car is a 2004 545i with Sport suspension and 8" wide front wheels and 9" wide rear wheels. The wheels Im looking to buy are 8.5" and 9.5" wide. What will this do to the off-set? A quick calculation of .25" on the outside = about 6mm. These wheels have an off-set of 35 both front and back while the factory is 20 front and 32 rear.
so.... By my hair-brained thinking...
To get to the 20 offset on the front from 35, I will need to add the 6mm for the wider rim getting me to 29, then add a 9mm spacer?
Not sure if the above is relatively correct, but if so, this would mean that I am already at 29 on the rear without any spacers and the factory is 32. Big problem, or am I over-looking some wiggle room and 29 on the back will be ok?
Help a brother out and guide me through this ordeal... I dont need any rubbing and would rather get this rright the first time and tell everyone the folks at 5series.net really know their stuff!
