To clarify on your fitment questions, are you asking about running an 18x9.5" ET35 square fitment? If so, I would not suggest that. The 18x9.5" ET35 used to be the only wheel available in our ARC-8 lineup that offered E9X 3 series customers the ability to get a concave profile 3 ARC-8's front and rear. The issue however is that this wheel specification up front dooes not have very good strut clearance, and would require 5mm spacers in order to clear the suspension (or thicker depending on the suspension at hand). Furthermore, in order to clear the front outer fenders, you would need to install adjustable camber plates. All of this is no problem if your goal is to run these wheels on the track, installing 255/35-18 or even 265/35-18 tires. Track cars would very likely have adjustable camber plates already installed.

For street cars (especially one using winter tires) with no intention of installing camber plates or running substantially wide track rubber, there is no reason to run the 9.5" wheels. Our newest ARC-8 18x9" ET30 square fitment is much more versatile. It offers the same concave profile 3 face as the 9.5" wheel, but without the fitment hassles mentioned above.

Please let me know if you have any further questions

Ryan,

Many thanks for the PM.

Sorry, I should have clarified....

I currently run OEM F8x 640M winters on my E91 LCI. 18x8.5 ET27 front & 18x9 ET29 rear.

Originally I fitted 255/35/18 rear & 225/40/18 front PA4's & the rears ballooned much more than the fronts did, the rear also caught the arch slightly... so I fitted 235/40/18 PA4 instead on the 9j rears which has cured the rubbing. However now I have the opposite effect with my fronts balooning more than the fronts!

I still have my 255/35/18 PA4's in storage though so I have the correct tyre sizes to suit either of the STAGGERED options either...

9j w/ 235/40 & 9.5j w/ 255/35

OR

8.5j w/ 225/40 & 9.5j w/ 255/35

So either way the rear set up would be a 9.5j w/ Mich PA4 in 255/35/18 flavour.

I just want to make sure the rear 9.5j with 255/35/18 winter won't be a clearance issue at the back with lowered suspension on a E91 LCI

Copy that, thank you for the clarification. Naturally the 255's will have a touch more sidewall stretch on the new 9.5" wheel in comparison to your old 9" wheels. This might supply you with just the look you are going for in effort to match up better with the fronts

Thanks - thats my plan!

I'm guessing you dont anticipate any rubbing issues with that set up?

My summers at the back are are BBS CX-R (19x9.5 ET32) with a 255/30/19 Conti SportContact 6 - and I have zero rubbing!

Correct, the fact that you are going with 255's instead of 265's on the 9.5" wheel should provide you with a rub free fitment

I will be lowered on coilovers just not sure how low yet. I am willing to do fender work to get them to fit so I will ask the shop to set a proper ride height for me when they do the alignment as well.

Question is, how wide of a tire can I go? Also, how much heavier are the 19's compared to the 18's?

[R99]

Does anyone have pictures showing the 9j fronts with 235/40/18 & the 9.5j rears showing 255/35/18?

Thanks !

Appreciate your interest. What suspension / coilovers are you going with? I ask because some may effect front strut clearance. Although you mentioned that you are performance oriented, am I safe to assume that this wheel/tire setup will be for street use only?

If you are open to adding a bit of negative camber, and/or rolling your rear fenders, 275/30-19 can easily be used. I would suggest the following fitment, assuming you are interested in the 19" ARC-8 design:

Front: 19x8.5" ET35 profile 1 or 19x9" ET38 profile 1 - 245/35-19

Rear: 19x9.5" ET33 profile 3 - 275/30-19

Below is a comparison of wheel weights between 18" and 19" diameters with identical widths and similar offsets:

Front:
ARC-8 18x8.5" ET38 - 18.45 lbs.
ARC-8 19x8.5" ET35 - 20.45 lbs.

Rear:
ARC-8 18x9.5" ET35 - 18.85 lbs.
ARC-8 19x9.5" ET35 - 20.5 lbs.

As you can see, the 19" wheels are approximately 2 lbs. heavier.

Thanks for the informative post, Ryan. Yes this will be for street use, and I will be using th ST XTA coilover. I've decided to go for the 19' wheels too. My only concern is that I wish to get the concaved profile 3 on the fronts as well. Is this option available on the 19x8.5 ET 20? Assuming that will fit that is.

Sure, you can run the 19x8.5" ET20 up front (as pictured on the front of adict's car above), but it will require a touch of negative camber to prevent rubbing the front fenders.

One front wheel left in stock.. ugh, thats just unlucky. Unfortunately this sale is only active as supplies last, so backordering them at the sale price is not a possibility.

No worries, I ended up ordering the PS-7 . Was just wondering, I ordered them the size I listed above, and apparently these would only be available in the profile 2 version?

I would prefer the profile 3 but looking at the sizes that support profile 3, I probably wouldn't be able to run that on my car I am assuming? (pre lci e92 non-M)


EDIT: add wheel size
19x8.5 et 20
19x9.5 et 33

Right on! The PS-7 & EC-7 face profiles work a little differently then the ARC-8. The ARC-8 only has a profile 1 and profile 3. It is either flat, or concave.

The EC-7 and PS-7 designs have a face profile 1, 2 & 3, so the concavity increases as the wheel specifications become more aggressive. The PS-7 profile 2 is quite concave, as the spoke layout/configuration/shape really accentuates the wheels concavity. I think you will be quite happy with them

We greatly appreciate your support, and be sure to post photo's of her!

Yep fits perfect in front. Keep in mind my V1's aren't that low though. Might rub if they were a little lower. Here's a few more pics

I will for sure, car won't be done until spring but I will post some for sure! BIG thanks to your service. Really can't say enough about it. Fast, friendly, very informative. On top of that, a great product for a great price. Can't ask for any more than that to be honest.

Ryan/Eddy/whomever what does it take to get a 17x9.5 et35 to work on the front of these damn things With a 255/40-17? I am trying to see if I can dual purpose some 17's for an e93 335 and my E90M (the E90M would need spacers for the et35 but that's no big deal) and if I can get away with them at stock height adding some camber on the e93 that'd save me buying narrower 17's that I wouldn't use on the M once the e93 moves on. Worst case I buy 4 et35 9.5's and two narrower fronts for the E93 and just run staggered on the e93. Curious to hear your thoughts haven't seen a whole lot of info on that particular front fitment. If it requires a too narrow stretched tire I would just run the narrow wheel

What's got me thinking seriously about this is Continental is releasing a new 275/40-17 and 285/40-17 tire soon to replace the DW and it's supposed to be comparable to PSS finally which makes a 17" street option attractive for the M till now all the tires in those sizes were r compounds or designed in the 2000's

Sorry to take it a little off topic but I swear I just want to see pics of the 17x9.5 on the front of. An e93 . I know there are easier fitments but e93's are fat bastards and need lots of wheel/tire

Happy to help.

The ARC-8 17x9.5" ET35 can absolutely be used as a square setup on the E9X 3 series with 255/40-17 tires. The front of the car will require spacers for proper strut clearance, as well as negative camber for the tire to clear the front fenders. The spacer size will depend on the suspension type, vehicle ride height and tire brand, but 5mm spacers typically do the job. As you may know, pulling the camber pins or installing adjustable camber plates will allow you to dial in the camber needed.

Important note: For most E9X 3 series owners, the ARC-8 17x9" ET30 is a better option for a square fitment. This wheel will support the same 255/40-17 tires, has a profile 3 concave face, will sit within 1mm of the 17x9.5" ET35 in terms of outer fender clearance, but most important has 11mm more inner clearance towards the strut. This results in a direct fitment, with no spacers required.

With that said, the 17x9.5" ET35 will give racers and weekend track warriors alike more sidewall support if the goal is to run r-compounds or slicks (they run wider then your average street compound and could use more shoulder support in the corners).

Richbot - I know you have a good grasp on all of this stuff, I just want to be thorough for others that may be reading In your case I understand the benefits of going with the 9.5's, and that is so that you can throw them on the E9X M3 with 12mm or 15mm spacers on all four corners.



Here are some photo's of the two square fitments for reference:

ARC-8 17x9" ET30
255/40-17 Street Tires
No modifications
* Note: We recommend a touch of camber up front with 255's, but 245's are an easy direct fit.
