Cool! These will definitely be the wheels I buy as part of my next round of mods. A few quick questions though. This would be the first time I've bought aftermarket wheels and I'm searching for answers as much as I can (learning a lot too!), but I still haven't found certain answers. Apologies if these questions are rudimentary/constantly asked:
1. I would be running these with Vorshlag camber plates and -2.5 to -3 camber in the front and probably -2 in the back, otherwise completely stock. Of the sizes above listed as "M3 Fitment", what is the largest wheel that would fit in the front and rear wheel wells, and do the camber plates and settings change the answer to this question? I know that fit will also depend on tire size, but for example will some of your wheel sizes not fit in the front or back no matter what tire is used? 2. Looking at acceptable wheel sizes for various tire sizes, it seems that tires that fit a 9.5" wheel also tend to fit a 10.5" wheel, and tires that fit a 10.5" wheel also tend to fit an 11" wheel. What should I take into consideration when deciding which wheel size to use with a given tire size if more than one wheel size will fit the tire and the car's wheel well? I'm assuming it's not aesthetics or widening the vehicle track since the indicated offsets suggest that wider wheels add most of their width on the inside, which would actually narrow the vehicle track. 3. Your website results page for the E9x M3 wheels has a glitch. The 11" wheel's offset is listed on the summary page as ET27, but when you click to that wheel it's listed as ET25, which is what's posted here as well. Page I'm referring to: http://www.apexraceparts.com/3-Serie...2-M3_c_33.html

All of the wide wheels we offer work with the e9x M3 platform in the rear, you just have to make sure you are getting the correct tire sizes. The front of the car can take up to the 18x10.5" ET25, but that is not something normally recommended as you would need to do some modifications for it to work such as removing fender liner and possibly a small spacer so that the wheel and tire clears the strut. 2. Though tires can fit onto multiple width wheels, the sidewall would be different depending on the width of the wheel, thus changing the characteristics of the tire and how it responds to the car. For example, if you put a 275/35/18 on a 18x9.5" ET22 wheel, the tire's sidewalls will bulge since it is oversized slightly and would cause a little sidewall flex. Move that tires to the 18x10" ET25 and it would have the correct sidewall support, and should be relatively straight & stiff, thus would respond as it should. If you go and put that same tire on the 18x11" ET25 wheel, the tire sidewall would then be slightly stretched as the tires are a bit undersized and can make the car a bit twitchy. Wheel and tire size choice would solely be dependent on what you are looking to gain from the wheels and tires. If you are simply looking to put the widest rear wheel and tire on your M3, you can get the 18x10" ET25 and 18x11" ET25 staggered setup to run a 295 or in some cases the 305 width tire in the rear with some fender work. If you are tracking the car and looking to neutralize the car from understeering, you may want to go with the 18x10" ET25 squared with a 275/35/18 tire all around. 3. Thank you for pointing this out, we will have that fixed! Quote:
For staggered setups, some people run 18x9.5" ET22 and 18x10.5" ET27, in which the 265/35/18 would have better sidewall support for the front. For squared setups, plenty of people run 275/35/18 on the 18x10" ET25 wheels as opposed to the 265/35/18.

^ Awesome, thanks so much David! I'm definitely looking for a squared setup to reduce understeer on the track -- I didn't realize the front could handle a 10" wheel with 275 tires and no modifications and still not rub, that's fantastic! That makes me wonder why so many people seem to run 265/35/18 all around at the track, though, since the cost difference doesn't seem very much and the number of tire choices between the two sizes seems to be fairly similar as well -- would the added size and weight of the 275s upfront negatively affect the steering feel, perhaps?
Thanks again, I think a set of these along with camber plates is definitely going to be my next mod! EDIT: I see the 10-inch wheel listed here as an M3 Fitment, but it's not listed as a possibility on the E9x M3 results page on your website (same link as I posted earlier regarding the offset glitch). Is that a listing error or is the EC-7 18x10 ET25 not usable in a square setup on a stock E92 M3? Also, would you recommend using the ET25 18x10" wheel on all 4 corners to maintain the stock relative track width (or near as possible), or would it be best to use a different offset front to back?

I just got my set on Saturday. They look great. I previously had ARC-8's on my last car, but these have a bit more strength, a tiny bit more weight, but lots better looks, IMO.
Running 275/35/18 NT-01 on 18x10 ET25 square. |

Very nice. Do you have any rubbing or fitment issues with the 18 x 10 front wheels?

We have had customers use 275/35/18 Hankook RS3s with the 18x10" ET25 EC-7's only rub on the fender liner at full lock or hard turning. The rubbing is very minimal and can be alleviated with added negative camber. Sounds like a phenomenal car, we would love to see photos of it!

Yes we do recommend that setup for no rubbing. You can even go with a 275/35/18 Hankook R-S3 and not experience any rubbing issues!

Those are the EC-7's in 18x10.5" ET27 fronts and 18x11" ET25, and they are wrapped in Michelin Slicks, which is sized differently than normal tires. Front is 27/65/18 and the rear is 30/65/18, which is similar to ~280 width front and ~315 width rears.

Looking at 18x10 et 25 F and 18x11 et 25 R wheels with RS3's 275/35/18 F and 285/35/18R. Hoping this combo will fit with my StopTech brakes and stock ZCP suspension with GC camber plates with -2.3 camber front and -1.6 camber rear. Let me know. Thanks!

Just got these. They totally rock. Spent the weekend at Oregon Raceway Park, and had this shot emailed to me while I was going ~120 mph on the front straight.

any photos of 18x9.5 et 22 square without spacers? I am interested in this set since I have kw clubsports but I am afraid the rear might look sunken in.
