This fitment is available in all of our designs, and is a direct fit on stock suspension. However it may require 5mm front spacers in order to clear your particular suspension setup. For those wishing to avoid spacers, the 18x9.5" ET22 with 265/35-18 or 275/35-18 can be used as a square setup as well.

All of our 18" designs will clear the standard F8x brakes, but the ARC-8 has extremely tight clearance and isn't recommended.

The weights of each design are listed below:
EC-7 18x10" ET25: 22.45 lbs
SM-10 18x10" ET25: 21.0 lbs
FL-5 18x10" ET25: 20.5 lbs

Additionally, we do offer a great staggered set for the F8X chassis. We recommend 18x10" ET25 up front with 275/35-18 tires, and 18x11" ET44 in the rear with 295/35-18 or 305/35-18 tires. The staggered setup is a great way to control the massive torque of the car, while the 18" wheels will give you a nice meaty tire setup.

Hope this helps!

Hmm, well the benefit of me going with the 18 square setup as opposed to my current wheels is to have a meaty tire and the ability to rotate my tires.

I'm finding that ever since I went to a 285/35/19 rear setup on my current set of wheels, I'm not having any issues managing the torque of my car. IS it possible to go with a 285 square 18inch setup? or even better, to get super meaty, a 285/40/18 square setup? If not, my current 19inch forged wheels are lighter than your 18s and I'd probably just keep my setup. I feel like going with 275/35/18 square will basically give me a smaller total wheel diameter setup than what I currently have.

Thoughts?

That's a good question. 285 is a bit aggressive and may require additional modifications to fit. The 19x10" ET25 is 2.7mm more aggressive in the rear than your current setup, and 3.4mm more aggressive in the front. so you'd need to make sure you have the clearance available. 285s will also increase the front spacer requirement with Damptronic coilovers.

Given the more aggressive offset, the taller sidewall of a 275/40-18 would only make fitment more difficult, which is why we recommend the 275/35-18 in this scenario.

The reduction in overall diameter is about 4.8% or 32.4mm. This will trade a reduced top speed in each gear for a noticeable bump in acceleration.

Ultimately it comes down to what your priorities are for the car. 285 square can be done, but it'll definitely take some work.

Hope this helps!

What work would need to be done?

I currently have -2.5 camber in the front and -2 in the rear.

Car is not slammed as well but flush in the rear and 1 finger in the front.

The biggest area of concern is the front suspension, since the way it limits inner clearance can vary based on ride height, spring configuration, etc. The best way to test-fit, would be to mount one of your current 19x10.5" ET34 rear wheels on the front with a 15mm spacer. This will simulate the clearance of the 18x10" ET25 and give you an idea of how much additional spacer you'll need in order to clear the suspension. The 19x10.5" ET34 will of course be to aggressive up front to drive with, but this test is simply to simulate the inner clearance to figure out your exact spacer requirement. It can be quite a process, so feel free to give us a call and we can talk you through all the specifics.

The rear will likely be less of an issue since we know 275/35-18 fits without a problem. Only a light fender roll or slight negative camber adjustment may be required. However in most cases, tire compound makes far more of a difference than the width itself, so it might be worth just finding a more appropriate tire and avoiding the extra work of stuffing 285s up front. But hey that's all part of the fun.

I took a couple real world pics of how the 19x10 ET25 front & rear SM-10s in Anthracite look on a completely stock M3 ZCP with 275/35/19 Pilot Sport 4S tires.

I was like I don’t remember taken those pictures, then remembered you had the same color as me. I am biased, but they look great.

Hmmm after looking at all the photos, I think I’ll just go with an aggressive staggered setup in 18s.

Anyone in SoCal with 18 inch Apex wheels want to trade wheels with me? I currently have 19 inch Titan7 ts5 forged wheels.

Further, I find the 10” wide wheel to not be quite wide enough to offer proper shoulder support for my 275/35R18 front tires. If I were to redo my setup, I would go with 18X10.5ET27 wheels for the front. IMO a 9.5” wheel would only make this worse.
Am i correct in saying if you went to ET27 on the front instead of the ET25 the wheel would move out 2mm more?

It is the opposite. The greater the offset, the more inboard the wheel is.

Few pics from the racetrack with EC7’s satin black 18x10 ET25 square. I’m thinking about getting 18x10.5 square, do you have such wheels for the F80? Which ET do I need to get to be able to run 10.5 square front and rear without clearance issues?
I'm on Eibach lowering springs, otherwise stock suspension.

My 19" SM-10's wrapped in 275/305 MP4S.

Looking to slightly lower with either Eibach or Macht Schnell. Can anyone with that setup comment on rubbing?

Thanks!

Anyone have photos of EC-7's in gunmetal, bronze, and silver on a Lime Rock Grey M3/4? Debating if gunmetal will look good.

I see this brand come up a lot. Are these lightweight wheels like rpf1s?

Is that M4 mineral white? Did you do 10"/10.5"/11" in the rear?

No. But you might as well ask if they're lightweight like a bicycle wheel.

Enkei doesn't make RPF1s in F80/F82 sizes. The RPF1 that fits BMWs come in 18x8.5 et40. So you'd need a massive spacer to mount that on an M3 which makes the weight savings a wash. And after all that, you'll have skinny wheels with skinny tires. And I'm not even sure if they would clear the F80's massive brakes. No one's mounted RPF1s on an F80 and for good reason; they're too small.

These Apex wheels come in the appropriate sizes to maximize tire widths for BMW platforms. Their flow form wheels aren't the lightest wheels but they're not heavy either. They have recently introduced a fully forged line of wheels for extra weight savings. But they're main objective is to make wheels that can take lots of abuse before failure; weight comes after that. They definitely are dependable wheels and they have the track record to prove it.
