ET27 was an older offset used on our ARC-8s and EC-7s. We've transitioned the new 18x10.5 wheels to ET22, so ET27 no longer features on the guides. Fundamentally that offset easily fits in the rear of the car if you are sourcing used wheels. 285/30-18 is our base tire recommendation, but you can also run 295/30-18 in most street tire models without rubbing. Wider 295s may require a bit of rear fender rolling/pulling or additional negative camber in the rear.

Awesome, thanks Tom. I was planning on doing the 265 front 285 rear setup. I did score some nice EC7s off the marketplace here that have the 27 offset, so glad to know it will work. Can't wait to get them on.

I will throw in my two cents here. I have experience running a 18x10.5 with a 285/30/18 and now I am running a 285/35/18 and am much happier. The 285/30 is just too "short" for my taste and actually causes the speedo to read 3-4 mph higher due to size. I would recommend a 285/35 for aesthetic purposes but, of course, that's your preference, either will work. Also you may want to run a spacer with the et27. I actually ran the Arc's with et27 and the 285/30 out back. I had a 15mm spacer that worked well. I currently run another 18x10.5 wheel et25 with a 7.5mm spacer with a 285/35 tire and it seems to be really nice. Again, it's all preference the et27 might work for your taste just fine without a spacer.

Ended up doing the 265/35s in front and 285/35 in rear. I like the rear but wish I would have gotten something a little bigger up front. Also planning on running 10mm spacer in front and 5mm in back. Need to lower it now!

Very nice. Will look even better once lowered. What are the offsets? et27 rear and et22 front? If so, I highly doubt a 10mm spacer will work up front with a 265/35 but maybe the guys are Apex can speak to this. 10mm out back should be fine. I am looking to add a spacer up front to my 18x9.5 et22 wheels as well, I am pondering a 3mm (is it even worth it?) or a 5mm...Anyone have any thoughts?

Yes, 27/22. Here it is with the drop. There are 5mms on the front, nothing on the back. It should easily take 10s. Going to try that tomorrow afternoon,10s in front, 5s in back.

So yes, 10mm spacers will work on the front with 5s in the rear.

That looks nice. Do you have any additional angles (particularly of the front). So just to confirm the effective offset is et12 up front (et22 with a 10mm spacer) with a 265/35/18 tire? I was nearly 100% certain that would be a bit much but that's great to know. Do you rub at all? Here I am nervous to run et17-19 up front with a 265/35/18.

Thanks, yes, no rubbing on the 265/35/18 with the 10mm spacer in front. Here are some more (filthy) pics, not sure what you are looking for so just snapped some randoms, but let me know if you want to see something specific. Couple notes, I am running camber plates in the front with a slight negative, and I haven't done a 4 wheel alignment yet, but I don't anticipate that causing any issues.

Apex EC7 RS

19x10.5

These are just perfect on the E90. Car is a slicktop/single hump 6mt lowered on Ohlins R&T. No spacers, running 30/275 in front and 30/285 in rear.

Do the 18x10 et25 ARC8s clear the Stoptech STR60 Trophy kit?

Anyone running this?

Hi Guys,

So i have some questions and need help.

have my old faithful M3 e90 2011, been running on Öhlins R&T the last years, stock breaks with better pads, might get change these out later on but i do fairly well with these as we speak = me slow

Have been using the stock 18" 219M with stock tire width, and on this spacers 12 and 15 mm, for the looks.

But i am now tired of the spacers as i feel the vibrations in the range +125mph, i am sick of trying to getting rid of these and now want a wheel that sits flush without spacers.

ARC 8 in gunmetal, either 18 or 19"

Could you give me the options i have in both 18 and 19, would also like to have the setup if i chose to go staggered.

Hope to get some guiding here, thanks.

EDIT: Michelin tires are prefered, Cup2 is my weapon of choice.

Stick with 18" imo. 9"et30 or 9.5"et22 upfront & 10"et25 or 10.5"et22/25 in back.

FYI, quality spacers, themselves, don't cause vibrations. It'll be because the hub lip and/or rotor hub face is not completely clean and/or the wheel was not mounted on the hub lip perfectly/lugs tightened perfectly evenly (star pattern).

Spacers are an extra compenent, so there's greater chance of imperfect balance, but under absolute perfect installation/condition, don't, themselves, contribute to increased NVH.

That said, proper wheel widths/ofsets that negate the need/desire for spacers is preferred for simplicity ofc.

Sorry for the delayed response here. Any Idea if the STR60 Trophy kit uses the same brake clearance template as the ST60 380mm kit?

I can’t for the life of me source a solid template for the new trophy kits. Our V1 ARC-8 (used wheels) needed a 2mm or larger spacer for spoke clearance against the standard ST60 380mm. I can check the V2 wheel which we sell currently to verify clearances if you’d like that info, but it applies only to the ST60 kit: https://centricparts.com/SiteData/me...26D0-01_FP.pdf

Full details on what we recommend for most: https://support.apexraceparts.com/hc...-Fitment-Guide

What I think fits your question:

Square:

18x10 ET25 square + 275/35-18 tires.
19x10 ET25 square +275/30-19 tires.

Staggered:
F: 18x9.5 ET22 + 265/35-18
R: 18x10.5 ET22 + 285/35-18

F: 19x9.5 ET22 + 265/30-19
R: 19x10.5 ET22 + 285/30-19

Both square and staggered setups will be more flush than the OE, although some customers still choose to run spacers as you can see from this gallery thread.
