We would not consider the 18x9.5" ET22 conservative at all. It works and looks great in the rear with a 265/35/18 or a 275/35/18 tire. Here are a couple of cars using our 18x9.5" ET22 wheel with a 265/35/18 tire.




An 18x10" ET25 with a 275/35/18 tire is doable but if you use an extreme performance summer tire like the Hankook RS3 or Dunlop Star Spec than you risk rubbing in the inner fender in the rear. Here are some pictures of an 18x10" ET25 mounted up with a 275/35/18 Michelin Pilot Super Sport tire that runs slightly smaller than an extreme performance summer tire and does not rub.

I'm about to pick up a sepang M roadster and am thinking about the anthracite finish on these. Looking to put PSSs on them.

I am not up to speed on sizing wheels. I do not want to add camber plates and make fitment too complicated but would love as much concave of a profile as I can get.

Can you recommend the best wheel and tire sizes? I'd love as low a profile tire as possible.

Thanks

You could very easily use our most concave profile 3 wheel in the rear of your car. Either an 18x9.5" ET22 with a 265/35/18 tire or an 18x10" ET25 with a 275/35/18 tire could be used as a direct fitment.

For the front I would recommend our 18x8.5" ET35 wheel with a 235/40/18 tire. This is indeed a profile 1 wheel but in person they do have some concavity compared to pictures on the internet. Unfortunately it is very hard to fit a concave wheel on the front of a Z4M without camber plates. To give a comparison our 18x9" ET31 wheel is narrower than the normal 18x9.5" ET35 front wheel set up that most track guys will run but, the 18x9" ET31 will sit at almost the same point relative to the fender as the 18x9.5" ET35 so camber plates are also necessary for that wheel even with a narrower tire.

Excellent info, thanks

Can you suggest proper specs for non-M applications? Completely stock and not lowered.

[The HACK]

Sigh. I was hoping not to spend more $$$on the MZ4 coupe this year, but these wheels just looks so RIGHT on the MZ4 coupe...almost like it ought have come from the factory like this.

Going to have to call in a few favors...

For a non-m we would recommend our 18x8.5" ET35 wheel in the front and our 18x9.5" ET43 wheel in the rear. You would be able to use a 235/40/18 tire in the front and a 265/35/18 tire in the rear with your stock suspension car and not have problems with rubbing. The rear wheel would use our profile 2 concavity and give a nice staggered look compared to the front wheels.

Thanks for the quick reply! Love these wheels.

Love the look, I could not be happier with the Apex Wheel. I have gotten lots of complements at gas stations and when out and about. The 2nd picture was taken at Deals Gap. We got the looks when we pulled into the parking lot. Bikers could not stop checking us out.

OK, coming back to this question. What if I wanted to go with 19" wheels? What size recommendations would you make, if any?

Thanks again

Is that an aftermarket lip on there? What kind is it?

Unfortunately at this time we are not producing 19" wheels but may have something in the works for the near future

[STIHLBOLTS]

FL-Z - PM'ed you.

No prob, let me know when you do as I won't be doing anything till the spring anyway. Thanks

[TexasZed4MC]

sitting in the garage waiting for a Tuesday install!

[David@ApexRaceParts]

Can't wait to see them mounted TexasZed4MC!

[Sirhan]

There is no place for the ///M sign on the rim ....

[TexasZed4MC]

I snapped just a couple crappy iPhone pictures at lunch after the install. Hopefully a photoshoot this weekend.
18 x 8.5 et 35 front with 225/45/18 tires
18 x 9.5 et 22 rear with 255/40/18 tires

I just used the stock tires I had, that were in very good shape anyway.

Side note: The car feels better with these lighter wheels. Far less sluggish

[dubsesd]

Looks awesome. I like it!

Agreed!^ Thanks for posting up TexasZed4MC

[TexasZed4MC]

I really like the Anthracite color on the car. These are the best set of wheels I have had on the car. Now I want a track set in 18x9.5 et35 fronts and 18x10 et22 rears!
