I think the problem is as much height as it is width. The base car can run more tire (i.e. wider) since 18s are shorter. The anecdotal evidence suggests that a 265/35-19 in front is near the maximum one can run. Some people report rubbing; others do not. And that’s on stock suspension; lowering would make the problem worse. I’m not sure people who might otherwise prefer a square setup would consider a 265 enough tire in the back. A 30-series 19” tire might provide some options, but nobody makes a 30-series 19 in a 200tw.

Makes sense. Perhaps staggered will be unavoidable especially with a CS+ tune on track.
Wonder what the max rear would be then? It looks like Im stuck with the 788s until apex and others develop some good 19" options. Im not one to baloon tires that are too wide for the wheel.
Really dont want to have to go aftermarket bbk just to fit 18s but maybe thats the only alternative.

For M2C, if we want wheels that can clear the brakes we can technically run SM-10 19x9 ET30, 18x10 ET33 ? Do you think 255/35/19 and 275/35/18 tires would clear stock suspension?

Although we haven't tested it yet, this setup should clear the brakes without issue, and should be a direct fit with no modifications required. The 255/35 fronts may need a touch of negative camber for fender clearance, while 245/35 should clear with stock camber.

We don't have any real-world 10" SM-10 photos, but here are some 19" ARC-8s:

Hope this helps!

So a 19x9.5 ET28 SM-10 would clear the front suspension but 19x9 ET28 ARC-8 would need a 5mm spacer? Why is that?

Great question, and my apologies for the incorrect wording. The spacer is required for caliper-to-spoke clearance, not for suspension clearance. The spokes on the ARC-8 are a bit deeper than our other designs, making spacers necessary on certain applications where our other designs clear just fine.

While 19" FL-5 production has not been planned just yet, we might consider a production later in the year.

There is nothing set in stone at this time. We will keep the community updated if anything changes!

Unfortunately, we do not have any immediate plans for a 19" FL-5. We do have some 19" EC-7 fitments in the works, specifically for the M2 Competition. Here are a few fitments we offer now that will work quite well:

SM-10 ONLY:

Front: 19x9" ET30 - 245/35-19
Rear: 19x11" ET44 - 295/30-19
  • Depending on ride height and tire brand, rear negative camber might be required.

Front: 19x9.5" ET22 - 265/30-19
Rear: 19x11" ET44 - 295/30-19
  • Negative camber required up front.
  • Depending on ride height and tire brand, rear negative camber might be required.

SM-10, EC-7 or ARC-8:

Front & Rear: 19x9.5" ET22 - 265/30-19
  • Negative camber required up front.

SM-10 & EC-7:

Front: 19x9.5" ET22 - 265/30-19
Rear: 18x11" ET44 - 285/35-18
(See photo below)
  • Staggered wheel diameter setup for those looking to run racing slicks.
  • Rear 295/35-18 or 305/35-18 tires will require aggressive negative camber and/or rolled/pulled fenders. Fitment ultimately depends on the vehicle ride height, negative camber specs and tire brand as all are not created equal.



ARC-8 ONLY:

Front & Rear: 19x9.5" ET33 - 265/30-19 (see photo below)
  • At least a 5mm front spacer required for suspension clearance.



This should shed some light on what our current recommendations are for the M2 Competition!

Would there be a staggered 19" EC-7 fitment?

Would this be the 19x9.5 and 19x10.5 with the offsets discussed earlier?
If so what is ballpark release?

That is the plan, we are planning to mirror our 18" fitment, which is 9.5" ET28 and 10.5" ET40.

It would, however the tires would be a bit stretched. We recommend 265/30-19 tires on the 18x9.5" ET22 as well as front and rear negative camber. With 245/35-19 tires, I'd use the 19x9" ET30 SM-10 instead, which will be a direct fit with no modifications required.

Yep, those are the planned sizes. We are shooting to have these available in the first half of this year.

I'm sad to hear no 19" FL-5 for at least the near term but thanks for letting us know not to expect it.

Which offset to get??

Apex,
I'm looking at the SM-10s in 18x9.5" (primarily track wheels). Does the wheel sit in the same position to the fender with either offset, and only the concavity is different?

Which offset is recommended? I'd be ok using some smallish spacers--would that then require the use of wheel studs?

Want to get in on today's group buy...

Thanks for the post! The offset determines where the wheel sits between the fender and the suspension. The concavity is determined by the width and offset.

For a square 18" setup, we recommend the 18x9.5" ET28 FL-5 with 265/35-18 tires. This setup requires slight front negative camber, but is otherwise a direct fit, and was developed specifically for the M2.
