Did you guys change your painter? I noticed hyper black has a more chrome look than it did a while back when the wide 17's were first released

No sir, still the same paint process. Hyper Black does have slight variations from batch to batch however, and that is natural due to the multi stage paint process that is used. Photography plays a big role in the representation as well. In the sun, Hyper Black looks to be more of a silver finish, whereas indoors or in overcast conditions it tends to take on more of a shadow chrome finish.

I'm looking for an aggressive setup for a stock Z4MC. I don't want to need camber plates or spacers or to modify the fenders. I already have the 9.5x18 et22 rim for the rear. The tire of choice for me is the Michelin PSS. From what I've read, a 265/40 or a 275/40 will fit on the rear. What rim and tire size could I use for the front?

Typically for a direct fit, we recommend the following fitment for your Z4M:

18" Staggered:
F: 18x8.5" ET38 (Profile 1) - 235/40-18
R: 18x9.5 et22 (Profile 3) - 265/35-18 or 275/35-18

For customers wanting to run a concave wheel up front, then we recommend the following fitment:

F: 18x9" ET30 - 235/40-18
R: 18x9.5" ET22 - 265/35-18 or 275/35-18

The front will be close to the outer fenders on the Z4M, but it may work with 235/40-18 tires. It would require around -1.8 degrees of camber or more up front.

Great! Thanks for the info. Exactly what I was looking for! I only wish it was still Black Friday so I could get the front rims.

Low clearance? No problem.

These 18" Satin Black ARC-8s slide right over massive StopTech brakes.

I'm running stock staggered set up but really looking at upgrading to these arc-8 rims.

I really like the concave look on my black z4m. (satin black rims)

Current set up:
225/45/18 F
255/40/18 R

Looking at your concave sizes, will 18x9.5 all around work with my existing tires?

Thank you for the post! The 18x9.5 ET35 is going to be quite aggressive up front, and not recommended. For your Z4M, we recommend the following fitment as a direct bolt on:
  • F: 18x8.5" ET38 (Profile 1) - 235/40-18
  • R: 18x9.5 et22 (Profile 3) - 275/35-18

For customers wanting to run a concave wheel up front, then we recommend the following fitment:
  • F: 18x9" ET30 (Profile 3) - 235/40-18 (negative camber needed)
  • R: 18x9.5" ET22 (Profile 3) - 275/35-18

You could reuse your original tires, but they will be quite a bit stretched. The front 18x9" ET30 will be close to the outer fenders on the Z4M with 235/40-18 tires and would require around -1.8 degrees of camber or more. The 18x10 ET25 will also work in the rear, but it will be very close to the fender. Depending on what tire brand/compound you use and the ride height, you may need a minor fender roll.

Let me know if you have any other questions! I'm happy to assist.

Matt, thank you for your response.
My tires are brand new so I will need to keep them.
225/45/18 F
255/40/18 R
You are saying that I can use a 18x9 ET30 with a - 1.8 camber correction up front.
In the rear a 18x10 ET25 set up could work, again with existing tires.

Tires are BF Goodrich g-force A/S.

I'm trying to see if I can get away with the concave look up front and rear without rolling my fenders.

Last, do you have any images you could share that illustrate concave in the rear and regular flat face up front in case I have to go that route?

Hello Andy,

Correct! The 18x9" ET30 can work up front, but will require a touch of negative camber. Typically -1.8 or more is required to fit that wheel up front. In the rear, I would suggest going with the 18x9.5 ET22 as it has the same concavity as the 18x10 ET25, but will suit your 255 tires a bit better. You will not be at risk of rubbing when you upgrade to a 265 or 275 rear when running the 18x9.5" ET22. The 18x10" ET25 may require a fender roll with 275's.

Here is an image of a flat faced from and concave rear wheel:

Not saying this will work for everyone but this is my setup:

18/9.5/et35 with Michellin PSS 255/35

18/10/et25 with Michellin PSS 275/35

Stock Suspension, no spacers, no rubbing.

Thanks for those photos! The car looks fantastic. Do you mind if we share your photos to others looking for fitment advice?

Thanks! I was honestly pretty surprised there wasnt any rubbing, not even under full lock. A good surprise though, haha.

And nope, dont mind at all. You're free to use them!

I've got a few more pics too to help anyone who's on the fence about different fitments.
