Hi all,

Hoping you can help and/or someone has had experience in what I am planning.

I have a 320i 2010 coupe. 18" wheels, tyre measurements below. The wheels sit in the wheel arch too much for my liking so I want to bring them out for a more aggressive look.

Potenza Re050a 255/35R18 90w

I wanted to add spacers to the front and rear. I've been doing a lot of reading and thought about 15mm for both but needed advice from someone who has added spacers to this car before. I'm more concerned about the looks rather than performance.

Also, what would be the cons to doing this for this particular car?

Any advice would be greatly appreciated.

Here is one of the rear wheels

15mm at the front and back should be fine. I ran 15s at the back and 12s at the front and it was not flushed with the fender but very close.

The only problem may be if you ever decide to lower the car , 15s may rub ... that is the reason now I ran 12s all around but its not flush , at least it does not rub anymore and still looks somewhat aggressive

Brilliant! Thanks for the reply. I don't think I will lower it but if I play it safe with 12mm I could always change my mind in the future.

Have you got any pictures of yours with 12mm and/or 15mm? Would be interesting to see the difference.

I run 15mm front and 20mm rear on an E90 LCI, but a lot of things play into that. Width of wheel, drop, control arm replacement, camber, offset, staggered/not, car model/LCI, if you got a lot of junk in the trunk (rear sub box, frequent big passengers, etc)

Best definitive answer is measuring your particular setup. Here's something that should give you some guidance:

12s all around

9.5" wheel 45mm offset, 275 tire with 20mm spacer.

Looks great. Any rubbing?

[10RN]

A lot of people have a larger spacer for the front a lower for the rear.
What do you think of 20mm front and 15mm rear? Or would that cause rub and/or be too aggressive?

Alternatively 20mm rear and 15mm front?

Well here's where I'm coming from

I put 12.5 in the front and it's super flush and looks super good and I put 15 in the rear and it has a mile of space left to go so in my opinion....

15 in the front would probably problematic and cause rubbing issues
20 in the front would probably... be bad

After having 15 in the rear I can say, with stock wheels I'm going to for sure be ordering 20s. 15 isn't enough.

Thanks!
I've already ordered 20&15 so I will put the 20mm on the rear and 15mm on the front. If it rubs I'll just change to 12.5mm.

Have you got any pictures of yours?

Not handy, no, I'm still trying to get fitment right lmao so I haven't really taken any pictures until I get it the way I want it know'm'sayin? Springs and spacers and dampening and yadda yadda it's a real chore to get it right lmao.

Haha I understand!

Good luck with it.

I will try and post mine once them arrive in the post later this week.

It's going to be about you. As I was alluding to, there some differences between models:

- E90s are different than E92s in track (especially the LCI), so your references here are skewed. I see now that you have an E92...that would mean my references and any other E90 LCI would have zero meaning to you. There's an 8mm difference between Pre/Post LCI E90s as well as a variation between E92s.

- Your drop and driving style will also play into this as 'cruisers' will have less issues with tight specs than people going over potholes on H&R sports drops.

- Your offset of the wheels you've chosen will make a difference as well as the tire profile. All of those (plus above) factor into how deep your wheel sinks into the wheel well. All you have provided for us is the tire profile, and that's just not enough. So all these pieces of advice mean nothing without true reference.



I was told this a few times as I was hunting, but you really need to first provide the rim and specs that you're looking at/using (even if its stock) and then work from there with some tape. We can provide a general idea, but the profile of each car can be slightly different for various reasons.

I also see a couple people giving you advice with aftermarket rims which all have different specs and are sometimes custom spun for their setup.

Ah apologies I didn't make it very clear.

Thanks for the advice, will take it on board. I watched the video and have made the measurements (although not sure they are entirely correct) but made the mistake of just ordering the spacers anyway.

Will see what happens when they turn up.

[10RN]

Finally fitted the spacers. Really pleased with the chunkier look

[10RN]

Had this setup (20mm rear and 15mm front) for 2 weeks now. I haven't had any rub whatsoever - if anything the handling seems nicer.

Next job is to lower to close the wheel arch gap.

Bumping up this thread, just wanna know if I'm changing to M3 rear bumper and will push out my rear fenders to match, what is the recommended spacer size to go? On E92 LCI.
