Hey everyone. Currently I am running 17x8 ET34 225/45 R17 on my 335 sedan. I really don't like how far in the wheels are on the car and wanted to move them out a bit with spacers.

After reading a lot it looks like if you get the right ones they can be safe and not cause damage to the car from driving or from hitting pot holes. In the rear of the car I was thinking 15-20mm but the fronts don't need to come out as far until they are flush with the wheel well. Is it ok to put 15mm on the back and 10mm on the front?

Will this cause any strange performance or tracking issues having the tire geometry off by a bit?

Is it safer to run the same offset on all four wheels?

Thanks!

As long as you run a high quality hub centric spacer with the proper lug bolt lengths you should not have any kind of issues safety or performance wise.

I would recommend getting a tape ruler and seeing how much clearance you have available from the tire to the fender and purchasing accordingly.

I plan on running +10mm front and +15mm in the rear. I know someone running +20 front and +25 rear and looks sick but you have to roll fenders.

I'll be running stock oem 162's on Michelin Pilot Sports 18x8 +34 and 18x8.5 +37 so running these spacers would make the new offsets +24 and +27. Pretty conservative and no fender mods necessary.

Thanks everyone. One more question; will having the front tires a different offset from the rear tires cause and handling to tracking problems?

Please post a picture once you finish - I want to do this on my m-sport sedan.

Pics please - both of you - when you get it done.

Does anyone know an answer to my previous question about running the two different offsets? Also, will there be any issue doing two different offsets with my car since it's an XI?

No, different offests shouldn't be a problem. AWD isn't an issue here

You will however screw up your steering geometry if you change the front offset. Precise steering is something that BMW's are known for - but you ain't gonna have it if you start messing with the front end like that.

Ok, so just so I understand what you are saying;

I should leave the front wheels alone and just add the 15-20mm spacers to the rear?

If I add any spacers to the front you are saying it will screw with the steering?

Please confirm what you were saying. I'm close to ordering the spacers and need to know what to get. If I run the fronts stock and just add spacers to the rear it will not cause any problems with cornering or anything? I would think that having two different offsets would make things a little screwy. But, that's why I am asking here. I have never done this before so I don't know what works/is safe.



thanks!

Running different sized spacers front and rear is not an issue, however it does widen the track of the car and can change the handling characteristics.

We always suggest measuring as each setup can vary just a bit. Measure from the face of the wheel to the edge of the fender to get a working distance. We suggest keeping spacers a few MM's under the maximum measurement to prevent rubbing issues.

We have a large selection of wheel spacers available for the E9x platform that can be found here on the website. Kits are available with and without extended bolts, but for any spacer over 5mm, longer wheel bolts should be used.

Reading throught all replies and no one give you a clear answer?

I know what you are asking. Just leave the front wheels alone, adding spacer to the rear alone will not causing any issue as far as I tried on my M3 and haven't notice any different. So I would say go for it.
