Hi guys. I’m about to purchase a set of arc8 18x9.5 et35 and 18x10 et25 for my e93 335i. These wheels were off a e46 m3. I seen a few people fit this fitment and it’s flush. What else is needed to have it on my car? I’m having my fender rolled on Tuesday and going to run 255 35 18 on the rear. Need your input. Also if anyone have pictures of the same setup on a e92/93 I would like to see.

Bump
I too want to see what else would be needed to fit an aggressive set up like this on a E93 and I'm in for some pics too

I run 275 in the rear on my e92 with arc 8’s as well. I’m not rolled with no rubbing

Are you in stock suspension? And you got any pics

Happy to help here The rear wheel specs that you are purchasing are aggressive as you mentioned, but many seeking a very flush fitment have gone with an 18x10" ET25 and made it work.

Let's dice this up into front and rear sections to keep things organized.

Front: We would prefer the 18x9" ET30 (which also has a profile 3 concave face like the 9.5" wheel) for the front end of an E9X 3 series, as this is a direct fitment with plenty of inner clearance for most suspension designs. 235/40-18, 245/40-18 and 255/35-18 tires sizes have all been used with these 9" wheels, and are supported well. Tire size one should choose would depend on the tire brand (not all are created equal), what rear wheels and tires you plan to pair them with, and how you plan to use the car (street, drag, track, race etc.).

The slightly wider 18x9.5" ET35 is not really beneficial to the driver unless the car is a serious track/race car, has an aggressive track alignment (neg camber) and will be installing 265/35-18 tires up front. The 18x9.5" ET35 takes up an additional 11mm on the inside, that means the wheel and tire will be 11mm closer to the front suspension components in comparison to the 18x9" ET30. The tolerance between inner wheel and tire and front struts is now very tight, and unless you run a very stretched tire, you will end up needing to install spacers (5mm at minimum).

Since the 18x9" ET30 sits within 1mm of the 18x9.5" ET35 wheels in terms of outer fitment towards the front fenders, the wider 9.5" wheel isn't any more flush.

In review the 18x9" ET30 is lighter (and slightly cheaper if buying new), provides proper sidewall support for all popular front tire sizes, has the same concavity, has 11mm more inner clearance, and is just as flush on the outside in comparison to the 9.5" ET35.

Rear: Please note everything below assumes were are talking about the ARC-8 design. We currently do not offer the ARC-8 in a 10" wheel with E9X 3 series specific/friendly offsets. The EC-7 and SM-10 designs are offered in a 18x10" ET33, which is a great fitment for this chassis and will NOT require the same amount of preemptive work.

In the rear, most E9X 3 series enthusiasts install the 18x9.5" ET35 with 265/35-18 or 275/35-18 tires. This is a direct fitment, however E90 LCI owners have less room under the rear fenders due to a wider rear end, therefore the rear wheels sit more flush (by 7mm IIRC) and depending on the vehicle ride height and tire size/brand, they may need to roll their rear fenders and/or dial in a bit of negative camber to prevent rubbing.

For enthusiasts looking for a more flush fitment on the E92/3 or E90 non-LCI, 18x9.5" ET22 (13mm more flush towards the rear fenders) or 18x10" ET25 (16mm more flush towards the rear fenders) wheels can be used. The 18x9.5" ET22 is the easier fitment of the two, however it still may require a fender rolling and/or negative camber to prevent rubbing. It really comes down to vehicle ride height, tire size and brand, and alignment settings. With the 18x10" ET25, you will certainly need both fender rolling/messaging and negative camber dialed in.

In our opinion, it does not make sense to go through the trouble of running the 10" rear wheels, unless you are planning to run at least 275 (or 285) tires to leverage that extra wheel width.

OP, what suspension are you on? Since the car is a vert, I am assuming it will be used strictly as a fun street car. If that is the case, and you plan to move forward with your purchase, I would suggest running 255/35-18 front tires, and 265/35-18 rear tires. Up front you will need spacers and negative camber to make this fitment work.


Here are photo's to help. His r-comp tires run wide, so the rear 10" wheels make sense.
Front: 18x9" ET30 - 245/40-18 R888-R
Rear: 18x10" ET25 - 275/35-18 R888-R

What rear wheels specs are you running? There are many enthusiasts running 275's or even 285's out back, but wheel width and offset will make all the difference between easy bolt on fitment and rolling/pulling required.

Thanks for your input Ryan. I’m currently running stock sport suspension. My H&R sport springs are coming in soon so I will be running that with stock sport shocks. Right now my camber is at 1.9* hopefully lowering springs will add a bit more camber. Also rolling the fender this weekend to insure fitment is good. This will be a daily street 400hp car lol.

Copy that, thanks for the added info. To help put the power down, I would go with 275/35-18 out back, that is as long as you are okay with around -2 degrees of camber in the rear and rolling (possibly slight pulling) the fenders.
If you want a slightly easier fitment, then you could stick with the 265/35-18's I mentioned above.

245/40-18 tires match the height of 275/35-18 pretty well, so that is another option for the front. Either way, 245's or 255's, we would suggest adjustable camber plates up front to ensure you have enough of a camber range to work with (and to ultimately prevent rubbing your front fenders). Let us know if you need any additional assistance
