Is the Apex Arc-8 17x8.5 ET40 and your BBS 17x8 ET40? How would a 235 square setup be worse on the Apex wheels?

Yeah, I don't know what he's talking about.

I didn't say you should. Are you not remembering your comment?

You said ARC8's don't come in a good 17" 135i fitment:

Yet you claim your BBS's are "perfect"?

So a 17x8.5 ET40 is a poor fitment, but a 17x8 ET40 is "perfect"?

17x8 et40 is perfect for the front...but it leaves a lot of space in the rear fenders...

As BrokenVert points out, 18x8 is not the same as 18x8.5

From TireRack:

If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly.

Also, according to Yokohama, regarding a given tire mounted on different wheels:

A wider wheel will improve handling at the expense of ride quality, while a narrower wheel will improve ride quality at the expense of handling. Consider these compromises when selecting wheels.

[Adam135]

235 Michelins will fit on a 7.5 - 9.0" wheel. 8.0 and 8.5 will both work fine. Anyone that says they can tell a difference between 8.0 and 8.5 with the same tire is full of it.

What does this have to do with what we're talking about? The offsets on both the wheels in question ARE THE SAME.

Regardless of it you're using a 235, or a 245, or a 225 (all completely fine sizes on an 8.5" or an 8" wheel)...

If you consider 17x8.5 ET40 to be a poor fitment, then surely you can't consider 17x8 ET40 to be a "perfect" fitment.

That makes no sense. The extra 1/2" of wheel width doesn't cause a signficant issue, front or rear, for a given tire size.

I.E. if 235's on a 17x8 fit front and rear, than 235s on a 17x8.5 will fit front and rear. Thus, one can't be considered a poor fitment, while the other "perfect" as alleged by TheStig. That's just silly.

Why is this so hard to understand?

Because we're tossing around specs without regard to specific tire sizes, weight, how the wheel wells are filled, the potential for rubbing, fender rolling, etc. You know, screw it. Just stuff some 19s in there, I'm sure it's the best solution.

17x8 et40 with a Z1 Star Spec rubs the front on heavy dips.

245's on factory m-sport suspension though, right? Some of your posts are why I decided to do a 17" square setup (though it will be on 8.5 ET41).

We are talking about wheel fitments. Any fitment issues between teh wheels mentioned is due to the tire, NOT with the wheel. AKA, if a large 245 rubs, it's going to rub on both the 8" and the 8.5". A 235 will be 100% AOK on either wheel.

In case you missed it:

I mentioned wanting to see some ARC-8's in 17s.

Stig said "APEX doesn't make a good 17" 135i fitment".

Then proceded to say that his 17" BBS fitment was "perfect".

Well, that statement was just plain wrong, because the fitment of the ARC-8 and the BBS are darn near the same. And both would work equally well with his 235 setup.

APEX specifically told me the 17" fitment they offered wouldn't be great and would cause rubbing. They said the only situation they would find them acceptable is for a track car where rubbing civility isn't the highest priority. You can take it as you want, but when a company essentially tells you not to buy their product, I listen.

I really appreciated their honesty too, and continue to recommend them as a result.

Zero rub(with Supersports that notoriously run wide), no rings, no spacers. What else do you want?

It really isn't at all actually.

Yes and no. My suspension has dropped about 3/4" over the course of 90K miles - so in a way im lowered

Shouldve been more clear - for a stock suspension car its damn near perfect.

You need camber and a few other things to make a 8.5 et40 wheel fit a decent sized tire. Some people dont like dealing with these things.

Eddy at Apex has made many posts like this on the forum. I ran across it multiple times when I was researching square setups.

Here's the important part:

The stock wheels are conservative, but when you put a meaty tire right out there at the fender lip with an offset like that, then you'll get rubbing. So a rear fender roll will be required. It's one thing to do this with a "show" or "street" oriented tire combo, but for track/autocross we are talking about wide tires that will be flexing to their limit under load and you'll neeed all the room you can get. The problem is you didn't want to roll your fenders you wanted a bolt on setup. If you installed 235's then you wouldn't have rubbing front or rear, but now you're not even coming close to the grip the car really needs. (I run 235/40's on a 2400lbs E30 M3 and I need more grip). Yes you could get around with that much rubber, but it's not even close to optimal.

Maybe you got a different answer when you talked to them directly, but I don't see how the 17x8.5 ET40 Arc-8 would be worse than the BBS RGR 17x8 ET40 with 235's. I've always read Eddy's note as being anything beyond 235 square is a problem for *any* wheel on the 1 series (non-M) for an easy bolt-on setup because there is no offset that accommodates both front and rear for a greater tire width. I could be wrong though. It's happened before.

I don't know. My OZ ultraleggera are 17x8 et 40 225 on front as well and was told by tire rack any size bigger would require a roll or some modification.

Email I got:

Andrew,

These are the only photos of 17" ARC-8s on a 1-series that we have:

http://farm7.staticflickr.com/6137/5958566887_5d91a5634b_z.jpg

http://farm9.staticflickr.com/8466/8078400156_1230c250c7_c.jpg

These are 17x8.5" ET40, and not an ideal fitment for the 1-series. This is a race car so they do not deal with the nuances of rubbing on the streets.

Let me know if you have any other questions. Thanks!

- David D.

I'm not bothered either way. At the end of the day I got a lighter and significantly stronger(strongest option for our cars) wheel.

[Dmitry83]

Hi everyone,


I wear these in Winter:
http://www.drive2.ru/cars/bmw/1_seri...52324031/#post

It's Russian manufactured "Slik L703" forged wheels, ordered to the factory in stock size 7.5Jx17 ET47.
The painting looks a little cheap, but the durability of a forged wheel is amaizing. (Anyway these can be ordered in black or white, which is OK)
These are fitted with studded Goodyear UltraGrip Etreme 225/45/17 and this combo is absolutely bombproof for two tough -27 degrees icy-winters and is extremely lightweight, that is a great improvement for steering and comfort.

The set of 4 wheels costs $1000 and worth every Russian "kopeika"!

If someone travels to Russia and have some friend there- you can make a pre-order (1,5-2 month for production) at the Factory, and take the wheels with you then ($30-50 for delivery around Russia).
Each weights 8,0kg (say 9,0kg with the box).

Hope, someone could find this useful.

17" look so weird for me on a 1series.
18" alright - stock look.
19" looks wicked!

Wow. So because BBS didn't tell you the same, you think that somehow, magically, despite their similar specs, the APEX wheels just fit worse?



Again, 235's the the ARC-8's would fit, for all intents and purposes, exactly the same as your BBS wheels do now. Great.

Again, it's about tire size. Not an issue with the wheels. You'd run into trouble with larger 245s and 255s on your wheels too. JUST as you would on the APEXs, which is what they were referring to when they said you can having rubbing issues.

You went with smaller tires, just as you can on any 17x8/17x8.5" ET40, and have your same "perfect" fitment.

No one is saying you made a bad choice. We all like your wheels. We're trying to say your statements that ARC-8s wouldn't offer a similar fitment is just plain wrong.

Eddy was warning you that, with larger tires, you may rub. If BBS cared as much about you as APEX does, they'd have told you the exact same thing.

Just cut your post down for sizing.

I did talk to BBS. Their response was that so long as I ran the stock brakes or a reasonably sized Brembo BBK, I wouldn't have any issue. Their problem was with the 135i brakes primarily.

Given that 245 rubs in all sizings stock, what else would we be talking about for fitment other than 235?
