I'll get more pictures later.

Your car looks sharp!

Do you drive it during the winter, too; if so, what do you do to keep it looking good that far north?

Thanks!! It gets stored, we get too much snow up here and it's only rwd. I've only had it for 9 months though. I did a full paint correction when I got it and a ceramic coat helps make keeping it clean a breeze.

I want to switch my stock wheels to the staggered ARC-8 setup for my M235i xdrive. Guess fitment is the same as on rwd? Car is lowered on H&R sport springs.

If anyone with xdrive runs this setup, which tires did you choose? Because of possible transfer case issues I want to run BMW approved Michelin star marked tires. I’m not tracking so PSS is fine, although I would like to try PS4S. I tried to check Michelin’s web page but a bit confused of which tires to use. I will of course ask them if no one has input

Realistically the ratio between the overall tire height in the front vs the rear is more important for your transfer case than whether you run BMW-approved star marked tires or not. We've had plenty of customers run this staggered wheel setup with non-star marked tires with great results.

For xDrive with these wheels we would recommend the following tire size combinations:

225/40-18 Front
255/35-18 Rear

This will give you a 0.27% difference in diameter between the front and rear axles.

235/40-18 Front
265/35-18 Rear

This will give you a 0.39% difference in diameter between the front and rear.
Both of these setups are within 1% difference which is our target for xDrive equipped cars and will work fine with xDrive. Do not mix and match sizes outside of these combinations unless you are going to do a square setup. The wider tire option typically requires a rear spacer (5mm) and may require additional negative camber up front depending on your tire choice and ride height. The narrower tire option will be a direct fit with almost all tires except ultra-aggressive R compounds or slicks.

I would say the most common tires I see run with this combination are Michelin PS4s or AS4s depending on your climate. Continental is quite commonly run as well in either the extreme contact sport or DWS06+. There are many great tire options out there though.

Great, thanks for clarifying!
I plan to run 225/40-18 front and 255/35-18 rear, so it should be plenty of good tires to choose from. Looking forward to some lighter and better looking wheels for next season!

Hi Tom! My name is John Cirone, I’ve actually supplied some photos of my M235i on FL-5s for your Flickr page before and am very much still in love with me 18x8.5 + 35 255/35/18 square setup


That being said, is there any chance to fit a 265 up front? I’d love to run a 265 square setup or maybe a 255/265 stagger if you guys will ever make the FL-5 in another F22 friendly size since a 255 is as big as you should go on a 8.5

Grazie,
-Cirone

Thanks for the followup and the photos! We don't have any wheels that will easily allow you to run a 265 up front even in our other wheel designs. A tire that wide would require some significant alignment and fender adjustments to eliminate rubbing. The 2 series fenders and front suspension don't leave us a ton of room to work with. 265/35-18 is commonly run on the rear of these cars with our 18x9.5 ET58 EC-7 or ARC-8 wheels but it does require a 5mm spacer or trimming of the dust boot and inner liners in the rear.

I’m on KW clubsport, will I still have the clearance in the rear?

Is there anything you make with a x9 spec that would fit a 255 front and 265 rear?

KW Clubsport clearances in the rear should be fine, but you may not have as much clearance up front around the strut/springs.

We don't have any 18" wheels that are going to be good for a square wheel fitment with a staggered tire fitment front and rear. Our 18x9 ET42 wheels can work in the front and rear with 255 section tires, but they require front spacers and additional negative camber to prevent rubbing.

You may be able to run the 18x9.5 ET58 wheels in the rear and the 18x9 ET42 wheels with hub extenders and spacers up front, but its going to be an odd mis-mash of wheels and tires.

Could I just run the x9 square set (with the required spacer and camber) with 255F and 265R

[230iZTR]

Specs for the all new VS5-RS and redesigned EC7-RS just went live. I'm waiting for the 17x9et42 specs in January. I should definitely get the diff before a third set of forged wheels, but not gonna lie, I'm hyped on those VS5-RS's.

Couldn’t I just run that 18x9 +42 up front with 255 (and the hub extenders and camber, I have the apex extended lugs would just need the spacers and I already have -3 camber and I’m willing to go more) and run 265 rear?

I was set on doing ARC8R 17x9 in the future but these will be very tempting. Reminds me of the 513M which would never work on the F22.

Could you run 18x9 ET42 square? Absolutely! Would it fit under your rear fenders without rubbing with a 265/35-18? Probably not.

The 18x9 ET42 wheel will poke out 10mm more than the 18x9.5 ET58 with no spacer or 5mm more than 18x9.5 ET53 (effective offset with a 5mm spacer on the 9.5" wheel for improved inner clearance). This will make your wheel and tire fitment more aggressive with the narrower wheels while providing less sidewall support for the wider tire.

Since you are considering running a staggered tire configuration already and consequently are going to lose the ability to rotate wheels and tires between the axles, I would recommend the wider wheel that is also easier to fit in the rear of the car and supports the tire better. I suspect that you could eventually make the 18x9 ET42 work in the rear, but I don't see the benefit of running the narrower wheel if you still can't rotate wheels and tires.

Very excited about the new Sprint Line wheels in general and I'm glad to see you guys are as well! We haven't been promoting them on the F2X forums as we don't have ideal offsets (yet). Once we get 17" production spun up and on the way the 17x9 ET42 will definitely be an option, but I'm also going to be pushing for E82 and F2X specific offsets internally in an 18" diameter at the very least, possibly 19".

Our new forged production lets us build orders with lower minimum quantities which will make it easier to support some specialty fitments like the high offset 1 and 2 series stuff, but we need to get the standard 3 series and M fitments through the door and shipping out before we address the 1 and 2er markets.

I have no problem not being able to rotate tires, and running aggressive alignment specs as I don’t daily drive the car, I just really want a 255 front and a 265 rear

The rears can’t be rolled only pulled correct?

You mentioned a 5mm spacer is that for the rear?

Would the 18x9 +42 fit with a 255 up front?

I suppose the benefit in the x9 +42 is visual and smaller wheel = less weight in my mind?


That being said what do you recommend for a matching front for the 18x9.5 +58
(Not matching as in identical size, but what size with a wheel model that matches)


Thank you for all the info!!! You’re amazing Tom

Sorry for my delayed replies, we've been incredibly busy with the Launch of our new forged wheels.

The rears can’t be rolled only pulled correct?

Yes that's correct. The factory fenders are rolled from the factory for the most part although you may be able to shift inner fender liners around in the rear wheelweel to prevent rubbing if its minor. Pulling will yield more room but should be done very carefully.

You mentioned a 5mm spacer is that for the rear?

Correct, our 18x9.5 ET58 requires a 5mm spacer to prevent rubbing along the shock dust boot and certain sections of the inner wheelwell liner if you run a 265/35-18 tire. Alternatively, those areas can be trimmed to prevent rubbing.

Would the 18x9 +42 fit with a 255 up front?

With hub extenders and spacers or 12mm hubcentric spacers, yes. You will need to adjust your front alignment though and I would recommend adjustable camber plates in most cases. This is the setup that dradernh runs I believe with the wider 18x9.5 Et58s in the rear.

I suppose the benefit in the x9 +42 is visual and smaller wheel = less weight in my mind?

The weight difference between these two designs is going to be marginal at best. The 18x9 ET42 currently has a heavier weight listed on the site (18.65 lbs) than the wider 18x9.5 ET58 (18.2) when comparing ARC-8s. In the real world with production wheels averaged I would expect them to be nearly identical. The 18x9.5 ET58 fits more easily, is better for the tire you plan to run, and isn't much more expensive. That would be my rear wheel recommendation.

I would do the 18x9 ET42 in the front if you are willing to use spacers and dial in additional negative camber. If you aren't, then 18x8.5 ET38 arc-8s. These wheels are only available in our ARC-8s if you are looking for the 18x9 ET42 front wheel as I believe we discontinued the 18x9 ET42 EC-7.

That's right. I'm running the following:

Front

– Apex ARC-8 18X9 ET42
– Michelin PS4S 255/35-18
– TCKline Single-Adjustable Coilovers & Camber Plates
– -2.6° Camber
– Turner Motorsport Hub Extenders: https://www.turnermotorsport.com/p-2...xtenders-pair/
– VAC Motorsports 8mm Spacers
– Pulled Fender

Rear

– Apex ARC-8 18X9½ ET58
– Michelin PS4S 255/35-18
– TCKline Double-Adjustable Coilovers
– -2.3° Camber
– Turner Motorsport 5mm Spacers
– Pulled Fender

I have the BMW M Performance Brake Kit installed, and it required a front spacer; otherwise, the tire rubbed on the strut body. (When I was running an Apex ARC-8 17X9 ET42 with a Toyo R888R 255/40-17 at the track, I didn't need front spacers.)

My shop specified the 8mm front spacer size so the wheel/tire combo would fit with the MPBK installed. I could only find 8mm spacers at VAC, but you can always have a machine shop reduce the size of a larger spacer to the exact size you need.

Could I have opted for the MP4S in 265/35-18 in the rear? I don't know, as I didn't consider it, but I suspect it would fit without any drama. It's worth remembering that buying a single wheel and tire for a test fit is always an option. That's can be a more expensive way to go, except for when you buy two or four of something that can't be made to fit. I've done both.

Here’s what I’m currently running


FRONT
KW CLUBSPORT (has top hats with camber plates)
FL-5 18x8.5 +35
-3.0 camber
255/35/18 Nexen Sur4G
7mm spacer
APEX 75mm M14 BMW 5 Lug Hex Head Stud Kit

KW CLUBSPORT
FL-5 18x8.5 +35
-2.4 camber
255/35/18 Nexen Sur4g
APEX 75mm M14 BMW 5 Lug Hex Head Stud Kit



That being said if I wanted EC-7 And a 255 front and 265 rear I will need
Rear
- EC7 18x9.5 +58 for rear
- 5mm spacer for rear
- 265/35/18 Nexen Sur4G for rear
- -2.4 camber and fender lining trimming

- EC7 18x8.5 +35 for front
- 7mm spacer to clear shock body
- 255/35/18 Nexen Sur4G
- -3.0 of camber



Why would I need a hub extender? Would I Need one with this setup?

I’m currently running a 7mm spacer on the 75mm studs and have no issues
