I was about to fit the 235/40 F and 265/35 R but thought to double check. Keen to hear you views for this set up on stock m-sport suspension, no fender roll.. thanks!

p.s. i dont want any rub lol.
The Yokohoma Advan AD08 has a squared off shoulder so it does run a little wider than most tires, but not as wide as R-compounds. The AD08s would help you fill up the fender wells and should not have any rubbing issues with your M-Sport suspension with the recommended EC-7s in 18x8.5" ET45 and 18x9.5" ET58.

Hi David,

Do you think there would be any issues with these size AD08 running KW V1 around one inch lower and 2 degrees neg camber on the front?

Thanks

There is a possibility that the AD08s may rub against your spring perch due to the tires being a little wider than the regular street tire. However, there are no guarantees that it will cause an issue, as we've seen some customers bolt up our wheels in the 1-series fitment with extreme summer tires and not have any issues.

My contribution

EC-7 (Satin Black): 18x8.5" et45, 18x9.5" et58

Other details affecting fitment:
H&R Coilovers, E9X front/rear control arms
Kumho Ecsta 225/40 front, 255/35 rear
3mm front spacers, 10mm rear spacers

The current setup induces minor rubbing over dips at high speeds. Other than that, I'm happy with how the car handles (especially above 60mph) and how steering feels.

I'll have them on my car in a few weeks, if this winter weather will confine itself to the mountains where it can be useful for skiing. I'm going for an alignment this weekend to give me the best chance of a rub-free fit.

In the meantime, if someone else has photos, I'd be interesting to get a sneak preview of what's ahead.

Cheers,
Bryan

The +58 offset calculates to a 7mm increase in offset from the stock wheels, which is negligeable and quite honestly not enough of a change. The offset should have been at least a +53, if not a +50. The fact that someone would have to consider running a spacer on these wheels to get the offset to look proper is ridiculous in wheels made for the 135i. What makes it even worse is that the front offset is quite aggressive and looks strange compared to the weak offset in the rear. Very disappointing, and is the only thing that prevents these from being the perfect wheel.

Overall, im still very happy with them, but the offset issue sucks. And no, i dont believe a 265 tire would have changed the offset enough to alleviate this issue. That would also not change the fact that the front and rear offsets are so far off, with the fronts being much more aggressive than the rear.
Let me explain the EC-7 offsets in more detail, as the offsets were selected with a very specific need in mind.

The ARC-8 and EC-7 wheel fitments are for performance oriented applications and not geared towards aesthetic only applications. This is a very important distinction as the fitment has to be different if the wheels are designed correctly.

A performance fitment implies that wide, meaty tires fit properly. Fitting wide tires is the goal, and making sure those tires fit under the fender is vital. A flush offset would guarantee fender issues, and that is a serious issue for a vehicle driven hard as rubbing/cutting of the tire could occur under extreme loads. Our priority is to make the car faster.

An aesthetic fitment is usually oriented towards being flush. The trade off is tire fitment/performance. To be flush, tires must be narrower and stretched, and/or a model tire that runs narrow compared to other tires in the same size.

We designed the EC-7 18x9.5" ET58 to fit properly with very meaty 265/35/18 tires, and in certain circumstances with careful attention 275/35/18 tires. higher 1 series specific offsets are needed to fit a tire like that. They simply will not fit properly with lower offset wheels.

The 18x9.5" ET50~ wheels you mention are very street oriented fitments and they sacrifice tire fitment. You cannot mount extreme summer tires or r-compounds in 265/35/18 or wider at 9.5" ET50 or lower without significant modifications to the rear fenders. Heavy rolling or pulling is usually not an option for most members. The ideal tire sizes for wheels with low offsets like that are 245/35/18 (stock size), and even then rolling is needed for a rub free fitment in certain cases. With extra work 255's can fit, but they are general more conservative street tires, or on applications that would significantly under perform in a competitive environment (auto-cross, track day, race...) compared to a proper fitment.

You selected Continental tires which run narrow compared to other brands. 255/35/18 is already stretched on a 9.5" wheel and it will exaggerate the conservative rear fitment due to the gap between the tire and the fender. A 265/35/18 would fill the rear much more but even a 265/35/18 Continental looks a bit stretched on a 9.5" wheel compared to many other models of the same size. An even meatier tire model/brand would fill the rear more without issue.

The ARC-8 wheel for comparison was spec'ed based on research by Berk Technology, and many other test fitments locally and from other vendors. Knowing that very few members actually needed a fitment as aggressive as their's, we lowered the offset by 4mm to ET58 in order to push the fitment out as much as possible without sacrificing the 265 fitment that 80% of the community is running on that width.

The fronts are aggressive in comparison due to the required offsets for a proper fit. There is very limited strut tube and fender clearance on a 1 series, and an 8.5" wheel pushes both those limitations on a stock car. These wheels were not intended to be optimal for 225 tires as that would sacrifice proper fitment for wider tires. The AERO-7 wheel on the other hand wheel was designed specifically for a 225 tire which is why it comes in an 8" width and a 45mm offset, which is much more street oriented.

The ideal fitment of the 8.5" front wheels are with camber plates in combination with wider tires such as 245/35/18 or even 255/35/18 with extra work. With camber plates the fronts would be tilted in more which makes them look less aggressive at the top. The front offset is needed to properly clear the strut tube as there is zero extra room to push an 8.5" wheel further in towards the suspension. It can only move further out.

If aesthetics are a priority, the rear can be spacer'ed out which is the benefit of a more conservative offset. The center bore on these wheels was designed so that the wheel maintains proper hub contact even when used with a 3-5mm flat spacer. There would be no issue pushing the offset out further if you would like to optimize your fitment for your 255 Continental tires.
+1.

I am thinking about the +62 in the rear for straight beefy tires as this will be a track only setup. What are the recommendations for a stock setup? I like to get max perf out of the car before i start tuning. Not gonna change anything but tires until no one else can absolutely drive it faster than I.

Alright guys i've read this post over and over to get the best combo for my application and I'm still not there yet. So I ask, EC7 in 1 series fitments with Michelin PSS. Car is lowered on Eibach Pro kit. Don't want to have to roll fenders or get camber plates or spacers due to rubbing...225 or 235 fronts and 255 or 265 rears?

They're on, but I haven't had the car outdoors yet to take a photo. I'll grab one tomorrow after work - you'll have to ignore the winter grim and the residual spoiler adhesive as I ran out of time last weekend.

The wheels look great - I leave home through the parking garage now so that I look at the car before going to work. The rear wheels fit great, but I'm not sure if the fronts will rub with my set-up.

I maxed out at -0.9 deg camber with M3 lower wishbones and alignment pins removed. I was hoping to get more, but both sides brought up on the end of a slot where the strut bolts come through the chasis.

Hope that helps!

Cheers,
Bryan

235/40/18 and 265/35/18 are still the recommended tire sizes for your car even though you are slightly lower with the Eibach pro kit. We have multiple 1-series owners using the EC-7's with these size Michelin PSS tires without problems even on their lowered cars.

Here are the photos. Unfortunately, the fronts rub on the bumper tabs, so Dinan camber plates are on order.

Track Setup

Will the EC-7 18 x 8.5" ET 45 Front and Rear square setup with 235/40/18 TOYO R888 fit on a lowered car without major rubbing. Or is it better to go with the EC-7 18x8.5" ET45 Front and 18 x 9.5" ET58 235/40/18 Front Tires 265/3518 Rear tires. Which will provide best performance on the track?

235/40/18 street tires are generally a direct fitment for the front of a stock car, and are a great improvement in width and grip over the stock 215/40/18 front tire size. Not all 235/40/18 tires will fit. R-compounds, slicks and some other tires may touch the strut tube, requiring a spacer to fit. This fitment is tight on both the strut tube side and on the fender side, so there is little room to play with on a stock car. If a 3-5mm spacer is used to clear the strut tube with some tires, then it would be ideal to dial in some negative camber into the front suspension to help clear the fender. The 235/40/18 tires are tall and could potentially rub the plastic inner fender liner if it is out of alignment. Plastic liner rubbing is usually considered acceptable by most owners, but it is something to look out for as the gills in the liner for the oil cooler can some times stick out towards the tire more than normal.

Since the R888 is an R-compound tire, they run much wider than a street tire so they may cause rubbing on your fenders. Because of this, you may have to downsize the tire size. Most people run staggered setups on the 135i, but there have been race cars that do switch over to a squared setup so that they have a more neutral steering feel, and the ability to rotate tires.
