Wheels are F 9" et38, R 10" et27. I realize that my tire choice is not helping the situation but they are optimal tire sizes for the wheels. That said, these wheels were purpose made for a perfect fit on E46 M3 and were a gamble for fit on the Z4M. My opinion is that the offset is about 5-8 mm too aggressive for the Z4M. On stock suspension it barely works. Any lowering would require a smaller tire and an aggressive alignment, and still might get rubbing. I have the front camber maxed out within what I can do with no camber plates. Honestly, I don't want much more than that because it is primarily a street car that we take on road trips and what not. I'll look for some bigger pics. When you sight down along the side of the car, the outer face of the wheel is dead on flush with the fender or may even protrude out a bit; viewing angle can make it look better or worse. But....I really didn't desire for something that aggressive on this car. What can I say, it was a gamble. The wheels are truly unique and maybe for a different Z4M owner would be the cat's meow, but I think I'm going to move on.

Pics - on stock suspension.














I dunno - every time I step back a look at it man, they are pretty racy looking. Maybe I should try a size down on tires. If I did, does 245/40 front and 275/35 rear sound right? These would have the closest side wall height to each other, and the 275/35 won't screw up the speedometer/DSC too much, right? Hard to decide to spend another $800-900 on tires just to see if it will work or not....
