Hi all

Sorry that I've posted here I've tried to look though all the existing posts and can't find the answer.

I have a 2009 e92 coupe m sport .with
Mv4s m sport 19" 225M
8x19 et 37
9x19 et 39

I'd like a wider stance or a deeper concave look but from looking at the data I don't think the csl wheels will fit there are a number of different csl withs and off sets

The genuine csl I found are
Front 9x19 et31
Rear 10x19 et25

I don't think they will fit the e92 the rear wheels will seriously rub using 265 or 275/30/19 tires the car is standard height but it looks lower than I've seen from others.

The other csl style is genuine bmw again
Csl style
8.5"x19 et44
9.5"x19 et27

With this the front wheels will look out of place the wheel will fit to far in the arch.

I guess my question is do the genuine csl wheels
Front 9x19 et31
Rear 10x19 et25 Fit the e92 with out rolling arches as I don't want to get into that . And what tyre sizes to keep the same rolling diameter

Any help be great
Steve

Can't answer you question but if you want to maintain any ride comfort you should really consider 18" instead of 19".

Hi David thank you for that yes I had thought of 18" but as they can with the 19" there seem to fill the arch a little. However as it came with run flats I really need to change them to normal tyres hate run flats

You need an et35 with 19x9.5 to fit 275s well.

You need an et35 with 19x9.5 to fit 275s well. 275/30-19 rear,235/35-19 front on 19x8.5 or 19x9 et30

Hi mate thank you for your help. I'm not sure if i really explained the question correctly.

I just wanted to find out if the genuine bmw csl wheels
9x19 et31
10x19 et25

Will fit the e92 coupe . ??

If not is there any other wheel makes i.e. Bbs that might be a possible?
I'm looking to reduce unspung weight

If you want to reduce unsprung weight, take a look at what your OEM wheels weigh and then compare what you are buying with OEM. 17" wheels are the lightest, 18" a little heavier, and 19" are the heaviest. The major reason for larger wheels is to fit larger brakes. Anything over 17" is going to ride rougher, but they do look good, although 19" with standard brakes looks lame to me.

Look at this website for most OEM wheels:

http://felgenkatalog.auto-treff.com/

Look at tirerack.com for aftermarket wheels, weights and offsets that they recommend. You will find that BMW uses offsets of 31 to 37 on the front and 25 to 40 on the rear. TireRack, last time I looked, offered wheels with offsets of 25-40. You can use spacers on a wheels with too much offset to get it to fit.

Some forum members have had success at going a bit beyond these limits.

You will also find that BMW uses maximum wheel widths of 8 on the front and 9 on the rear. TireRack offers widths of up to 8.5 on the front and 10.5 on the rear.

As far as "filling the arch", this depends on the diameter of the tire, not the wheel, and whether the car is lowered by sports package springs or other means. The car does look better lowered or with bigger tires. Most lower their cars to reduce the distance from the top of the tire to the top of the fender opening.

Hi thank you very much for the info much appreciated. As I'm not in the USA I don't think I can order from tire rack but it will give me a look to see what they might suggest. I understand smaller diameter wheels and tires will improve the ride quality and it's a fine balance ..

I am planning on weighing the wheels the weekend so have to compare I'm thinking a compromise to 18" diameter and a bit more tyre.

Thank you for your help though with the back ground information.

Dose any one here run the BBS CH wheels ?

You'll either need radical camber, roll, stretch, narrow tire, or all the above to fit the rears. Fronts are good. With the size i recommended, on mine I was a few mm from rubbing. If i went 265 I would gave had 8mm to work with to the fender. Those stick outward towards the fender 16mm more than mine did. Maybe work with a stretched tire. The offset is for e9x M3. Can you just get repos?

OP, the specifications that you have listed are the E9X M3 ZCP wheels. The E46 M3 CSL wheels are actually a bit slimmer - F: 19x8.5 & R: 19x9.5.

In regards to the E9X M3 ZCP wheels, the fronts will be a direct fit with 245/35/19 tires, however the rear wheels will require the rear fenders to be rolled. With 265/30-19 tires, you may be able to get them to work without dialing in too much negative camber in the rear, but it will ultimately depend on the vehicle ride height and tire brand. Bottom line is the 19x10" ET25 is a bit too aggressive for a direct fitment, and will require work for proper fitment.

I would recommend running 19x9.5" ET33 in the rear. This specification will provide you with a flush fitment, while allowing you to run a proper size 265/30-19 tire. This is a direct fitment, with no modifications required.

I would be happy to answer any further questions that you have.

Here is a photo of our 19" ARC-8's on an E92 M3 for inspiration. I will try to find you a photo of our 19" wheels on a E92 non-M as well.



Edit: Here is a photo of an E90 non-M with our 19" EC-7's.

Hi Ryan thank you so much for your help much appreciated for all the info with regards to the sizes that will fit with 19" wheels and I'm going to look based on that..

Just to throw on more thing in to the mix I've been offered

BBS CH
18" x8.5" front with et 35 With235/35/18
18" x10" rear with ET 40 with 265/30/18

From your information would this fit ok as trying to keep the diameter the same as what I have at the mo. I think with the ET 40 on the rear I think this may rub on the damper strut

[Fundguy1]

Rear et is fine. I have 19x11 et43 with 305s no rubbing. You can get a spacer. You'd want larger profile tires with 18s. Increase to 235/40-18 and 265/35-18.

Hi mate
I looked into that on the will they fit website .

I'm wondering if the 275/35/18 would be an option with out rubbing . With the rear being the 18x10 et 40

I don't really want the stretch look just normal square shape . I'm wondering it that will cause rubbing .

If you say you have 11 inch wide on the back with 305 tyre wow did you have to roll the arches on that or put more neg camber on it ??

[Fundguy1]

Yes it would. I fit 275 with 19x9.5 et35 on my pre lci e93. Should work. And for the 305s, roll and stretch.

No worries. I only posted info on 19" wheels because that is what you had listed in your OP.

Yes, the BBS CH's will fit in those specifications no problem. With that said, you rear tire size should read 265/35-18, as the 30 series profile is too short.

If you would like, you could also step up to a 275/35-18, and rolling the rear fenders should not be required unless you lower the car a good amount.
