That's the Varis style front lip. You can find it in polyurethane or carbon fiber.

Will this spec work?

18X9.5" ET35 APEX ARC-8 275/35/18

on

F36 RWD

Suspension: Stock M

Without rubbing/modifications?

Anyone have similar setup with pics?

Thanks!

Why would you put the narrower tire on a wider wheel? Did you mean 275 for the 9.5” wheel and 245 for the 9” wheel?

That was a mistake I edited my original post. Thanks for pointing it out

Hi there,

On a stock F36, that setup will likely rub in the rear under suspension compression, depending on your specific tire selection. This rubbing could be alleviated by a rear fender roll and/or a touch of additional rear negative camber.

For an easier fitment you could run slimmer tires on those same wheels, with a 235/40-18 front and a 265/35-18 rear. OR you can run a higher offset 18x9.5" ET43 rear wheel, which will give you 8mm of additional rear fender clearance compared to the 18x9.5" ET35, which could allow you to run a 275/35-18 without rubbing.

Hope this helps!

Looking at the Front: 19x9" ET28 with 245/35-19 tires
Rear: 19x9.5" ET33 with 275/30-19 tires arc-8 setup for my 435i.

Will this fill out the wheel wells on my car with the stock electronic damping? Im not sure that I want to get rid of the stock suspension in favor of coilovers.

Stock M-sport suspension with electronic damping.

update: I do not have xdrive.

Would arc 8 9” ET30 square with 255/40/18 be rub free on:

F36 with stock Msport suspension RWD with A/S tire like the newer Michelin a/s 4s?

I saw a post on here of a black F36 with the same wheel setup calming its rub free but it was lowered lowered on H&R with conti dws06+ and xdrive vs rwd. Is this sufficient to assume my setup will not rub?

Been reading tons and would really love to run 255/40 vs 245/40 squares.

Hi there,

The 18x9" ET30 square setup with 245/40-18 tires is pretty much a guaranteed rub-free direct fit on a stock F3X. In most cases, 255/40-18 tires are also a direct fit but can occasionally require a touch of additional front negative camber when running more aggressive performance-focused tire compounds. However, with an all-season such as the AS4, you shouldn't have any issues with 255/40-18s, especially with stock suspension.

Hope this helps!

This is an aggressive fitment that will certainly fill out the wheelwells of your 4 series. While you shouldn't have issues with inner clearance, depending on your rear tire you may need to roll/pull your rear fenders to prevent rubbing under suspension compression.

245/40-18 and 255/35-18 are the setups that are a direct fit across the board with different tire models. 255/40-18 should be a direct fit in the rear with these wheels, but depending on the tire model and your setup, so additional negative camber may be required up front to prevent rubbing which would require adjustable camber plates.

That helps a lot actually thanks a bunch I'll be ordering some arc 8s soon!

My apologies if this comes off lazy but can you tell me what is the max size/offset I can achieve for a square 19" set up without rubbing? No matter how much material I read, I cannot seem to wrap my head around wheel offset, relative to the overall width of wheel/tyre.

I have the OEM staggered 19" set up right now, I believe 255 rear and 225 fronts. RWD/M adaptive dampers, stock height. I like the more aggressive offset of the rears and would like emulate that for all four corners, if possible.

thanks for your help.

Hey, no worries, we're always happy to discuss fitment! For a direct fit with stock suspension and alignment settings, the widest/most aggressive rub free square fitment we recommend is a 19x9" ET28 or ET30 setup with 245/35-19 or 255/30-19 tires. This setup will work great as a direct fit with no spacer needed or any additional nonsense.

The widest square fitment we ever recommend for these cars without serious mods and fender work is an 18x9.5" ET35 or 19x9.5" ET33. With this size paired with a 255/35-18 or 255/30-19, you may need a rear fender roll, added negative camber, and possibly a 3mm front spacer for suspension clearance depending on the tire selected. Please also note that with a 9.5" width wheel up front, inner strut clearance will be very tight so this setup is not recommended for coilovers that limit inner clearance like KW variants, Bilstein PSS10s, Ohlin R&T, etc.

Feel free to search through our Flickr page to get a better idea of how each setup will look. Most photos will have fitment specs listed in the descriptions:

Thank you!

Soo... a 19x9 ET28 would poke out slightly more (2mm?) than a ET30? Or is it the other way around? This is where I can't seem to wrap my pea brain around because it is always opposite of what I think is intuitive.


A tyre of 245/35-19 would be slightly less wide but slightly more tirewall height than a 255/30-19?

I like the EC-7 for example, and I think that comes in 19x9ET30. However, the photos/specs I see listed on a 435i taken back in 2015 seem to indicate it was an ET40 at the rears. Would an ET30 be more aggressive? (https://www.flickr.com/photos/apexra...7632937145866/)

I like a slightly beefier stance without going overboard. Aside from the tune and exhaust that I already have, I doubt I will do any suspension mods and have peace of mind leaving it stock.

Hello,

Apex- is there a reason you guys stopped making the 19 x 9 or 9.5" wheels with the 40 range offsets? I would like to use them for a rear fit and I see in looking back through this thread and on others, you guys did make the higher offsets at one point in time.

Thank you!

That is correct, an ET28 wheel will be two millimeters more aggressive compared to an ET30 wheel with the same width. A lower positive offset means more aggressive or pushed further out towards the fenders while a higher positive offset (example: +50) will be tucked in towards the center line of the vehicle. This website can be useful in comparing two different fitments back to back:

Will They Fit?

Yes, a 245/35-19 tire will be both narrower and have a slightly taller sidewall in comparison to a 255/30-19 size. The link below is helpful in comparing the over all diameter of two different tire sizes:

Tire Size Calculator

The ET30 wheel is more aggressive compared to an ET40, however the square 19x9" ET30 fitment we recommend is a direct fit on this chassis at all four corners with a 245/35-19 or 255/30-19 street oriented tire compound. You can checkout our fitment guide for specifics on all fitment we recommend:

Unfortunately we just didn't see all that much demand for those sizes, mainly because the 18/19x9" ET30 and 18/19x9.5" ET35 can work as a direct fit with little to no compromise and give a more aggressive fitment. We do still offer the EC-7 in an 18x9.5" ET43 as well as our forged EC-7R and ARC-8R in an 18x9.5" ET45 size for those looking for a more conservative fitment.

Ordered a set of 18x9 ET30 ARC8s as they're back in stock!

Will be running 255/40r18 Michelin a/s 4 tires on my F36 stock msport suspension RWD. Stay tuned!

Tom,

I m going to run Michelin A/S 4s 255/40r18, I believe your coworker Geirsen confirmed that this setup should be rub free "especially on stock suspension".

I just ordered a set so should have tires in a week or two.

[gpchamp]

I'm looking at either the FL-5 or the SM-10 for my 2018 Gran Coupe. I want to keep my stock 225-45-18 front and 255-40-18 rear tires. What sizes should I get the wheels in?

[Emerson335]

Just ordered square ARC-8's 18x9 ET30 today, as well as Conti DWS 255/40/18. Should get them mounted/balanced next week.

My 2015 335xi is lowered on Eibach 05-22 springs and Koni Yellow struts. I'm currently running square factory 18" wheels/tires with 12/18mm spacers and some noticeable side wall poke without issue.

Fingers crossed the 255's will fit without rubbing, as I don't have camber plates and prefer not to. I was inspired by all the members here who are lowered (not slammed) like me and having good success with that size, and the Conti's are slightly smaller than the Michelins.

I literally just got my arc8s and gonna run same size tire tomorrow, hopefully no issues fingers crossed
