Another OEM 219 wheel question. I just ordered a set of 219s from a board member to put on my M3 e92. All 4 however are 18 x 8.5 size therefore offset of 29. Obviously this will fit the front perfect since its OEM but the rears are normally 18 x 9.5 offset 23. If I use all 4 18 x 8 offset 29 will I be OK without modification? All 4 tires 235/40/18

[M3SQRD]

If the stock 8.5et29 front wheel is used on the rear the front face of the wheel (or mounting lip) will stick in 0.8" compared to the stock 9.5et23. 0.8" is pretty significant and, personally, I'd run a spacer on the rear to correct the offset/frontspacing.

thats a 20mm spacer to make up that difference. wouldnt want to run one that wide i dont think. mount and see how it looks. i personally like a very flush look and that will be hard to achieve. you would need 15mm up front and 30 plus rear to get that look.

[mscdman]

I don't really care about the flush "look" per se. I'm more concerned with alignment/camber issues... Will there be an issue with this running the OEM fronts on the rear?

I am using 235/40/18 on all 4

And also want to make sure it won't hit the rotors or anything...

What spacers would I need on the rear to bring back to OEM specs? If I use a spacer on this setup in the rear to being back to OEM specs, will I still face camber issues?

i would think you would be fine with that set up but i just saw you have a 335 so not sure on that car. caliper clearance shouldnt be an issue because the lower backspacing number should push the face of the wheel out. what are the stock wheel specs for 335?

Thanks 1moremod. Are you saying I shouldn't even run a 20mm spacer cause its too wide?

The more I think about this the more I'm upset this wasn't listed in the sellers ad....

I have an m3 not 335. 2009. Old sig.

okay thats not that big of a deal then if im thinking about this right. stock 219 fronts are 18x8.5 et29 and rears are 18x9.5 et29. so putting the fronts on the rear will suck the face in half of the 1 inch difference or 12.7mm so a 12mm spacer on the rear will make it look like a regular rear as far as stance. the problem is you limit the amount of tire you can put on the rear. I track a lot and would want more not less particullary in the front. most people arent downsizing their rears except for maybe a square winter set up.

Thanks 1more! This is for a winter square setup. I have blizzaks 235/40/18. I still have the following questions:

1) Will it work without a spacer on the rear?

2) if I don't put a spacer on the rear will it affect camber/alignment?

3) so would it be a 12mm or a 20mm spacer I would need on the rear to being it back to OEM stance?

4) if I bring it back to OEM stance with the use of a spacer, will there be any alignment/camber issues?

5) what are the risks of using spacers?

Ugh. I'm frustrated I didn't know this before I purchased.

Stock rears are 18 x 9.5 ET 23 not 29. Front is 18 x 8.5 ET 29

if thats the case then they will be sucked in 6mm more than what i said before. so 18.7mm spacer to set back to same as stock rear.

[mscdman]

Damnit I'm pissed!! The sellers AD did not mention this. I fucking specifically wanted a stock OEM setup to avoid this spacer BS.

Update: I guess the ad did. Stupid me didn't read it carefully. Jesus Christ. I hope I can find a matching rear set to buy now.

1- not sure of the caliper clearance stock so cant say. you will have no trouble with the tire or rim inner clearance because you gain 6.7mm of space on the inside.

2-spacer wont affect camber or alignment. i run one on the rear at the track.

3-18.7mm

4-same as 2

5-low risk. i have run them for 4 plus years on my m3 and have had them on and off bunch of times. need to be careful you buy a good set Macht Snell is what i have used. taking on and off is difficult first time then you figure it out. should use antiseize on the inner hub contact portion so comes off easier. some poeple have had wobble or balance issues with spacer but i think its due to poor set or not seating properly on the hat.

if its for a winter set up i wouldnt worry about spacer as long as you clear the brake calipers. it will be pretty tucked in looking but its up to you. late in the season to worry for this year isnt it?

[mscdman]

Yeah it's late in the season, so ill probably keep them as a solution for next year at this point. Thanks so much for all your answers. Very helpful. As I mentioned, I don't care about the tucked in look in the rear, but are you pretty sure if I don't put a spacer on the rear it won't mess up my alignment/camber?

if you have the rims pull your rear off and mount one with or without the tire doesnt matter. you will be able to see if you clear the caliper. jack up the rear and spin or use a feeler gauge to measure your clearance. check the face of the caliper to wheel spoke clearance. rear calipers are rather small so might be okay.

yes im sure. the tire just mounts on the hub. camber and toe, i assume this is what you mean by alignment, is adjusted with the control arms that mount to the inner wheel hub assembly. you will have a narrower track width in the rear is all which shouldnt matter particullarly in the snow.

I have tried stock 219 fronts on the rear and they look fine, clear everything perfectly and drive very well. 4x 8.5x18 with 235/40x18 is spot on for a winter setup.

So it doesn't look ridiculously set in?

[slicer]

It's not a bad idea to run the 8.5's in the rear for winter use. As you probably know, narrower is better in the snow. I ran snows in OEM wheel / tire sizes (245 front, 265 rear) when I lived in MN which looked great but I can see how a narrower tire in the rear would have been nice (I struggled with traction once the snow got deep). As stated above, the size and offset of the front wheels will make them sit 18mm further in on the rear. I would purchase an 18mm spacer (and extended lugs). Spacers are not a big deal as long as they are installed correctly. My opinion is that this is not a huge issue and you didn't make a bad move buy purchasing this set. You need not be concerned about your suspension settings; they are independent of your wheel sizes.

All that being said... If I need snow tires in the future, I would run a 18 x 9.5 square set with 255/40/18's. The ultimate traction would be weaker than your set-up but I would sacrifice a little snow traction for the dry traction benefit of the wider tires and extra sidewall height over 235's.

It looks like a normal car not an m3. It gives you plenty clearance for chains in case you need them. To my eyes spacers would be an overkill. But looks are subjective. If I were you I would try them without spacers first.
