The finish is Anthracite.
The fitment that you quoted is very aggressive up front, and is used frequently on track oriented cars looking for more front end grip. The 18x9.5 et35 application used up front requires camber plates with a decent amount of negative camber dialed in. This allows the wider wheel and tire to clear the front fenders.
We do not typically recommend 19" applications for the Z4 M, especially if you are tracking the car. If your Z4 M is strictly for street use, and you prefer the look of 19" wheels, then the bolt-on fitment would be 19x8.5 et35 front and 19x9.5 et22 rear. The 19x10 et25 can also be used in the rear, but may require a slight fender roll depending on the tire size, brand and ride height. Tire sizes would be 235/35/19 front and 275/30/19 rear respectively. Here is a photo:
If you wanted to run concave front wheels like the white Z4 M in your quote, then you would use our 19x9.5 et35 application up front, paired with either 245/35/19 or 255/35/19 tires. Like his 18" setup, you too would need camber plates to dial in enough negative camber to allow the front wheel and tires to fit without rubbing.
