Hey guys, are any of you running 12 mm spacers on all corners? Last night I installed Macht Schnell 12s all around on my 335is with 19 inch 225M rims. The front rims are more flush than the rear ones, which makes sense because the rear is lower and needs more clearance anyways. From visual inspection, the 12mms seemed to give sufficient clearance for the stock hub to fit inside the spacer hub cutout. The stock wheel is chamfered so the spacer touches the hub flat, and the wheel sits on the hub flush also. Have not yet done a high speed vibration test, but I think it'll be ok. I understand running a 10 in the front could cause vibration issues because it's not wide enough...correct me if I'm wrong please.
Also, is it totally in my head or does the car feel more stable? 24 mm is roughly an inch widening of the track, front and rear. I feel like that is more than enough to actually make a handling/feel difference.

I'm wondering also, why the 15 front, 12 rear setup is so popular amongst M3s on stock 19s. The front sticks out so much wider than the rear and looks lopsided.

You have pics? I too was considering spaces on my iS and am curious to see what it looks like.

Are the rims 8" & 9" or are they 8 1/2 & 9 1/2 ? I have the 313's and they are 8 & 9, so I would need to add some mm's to my spacers.

My rims are the same size as the 313. At least with regards to diameter 19" and 8 front 9 rear on 225 front tires and 255 rears. My offset is 37 in the front and 39 in the rear for the stock 225M. I am sure the 313 are the exact same, if not within a mm or so.

I hit 140+ mph multiple times this wknd and didn't have the slightest wobble. I'm sure now that the 12mm hubcentric spacers give sufficient clearance for a proper install.

I was going to go with f=12mm r=15mm. Do you see any issues with an extra 3mm to the rear?

You need thicker spacers in the rear to get even flushness. On me staggered 17", 10mm in the rear made the front and rear pretty evenly flush.

Interesting from the pics the rear seemed more flush than the front already.

For mine, I would need 18mm at the rear to match the flushness of the front with 12mm.

I just check your car out and the car looks great! 12mm all around gives that nice flush look. Now the question is how strong are the spacers. Spacers is a piece of metal that is not apart of the wheel or the wheel hub, which well be facing stress from both areas. I havn't heard any stories about them cracking or breaking apart, but it sure does make me feel alittle comfortable sometimes going at high speeds. I used to run 12mm rear spacers and had no problem with them when I had stock wheels. I do plan on getting 5mm in the front and 10mm in the back. Not to bust your balls OP but just wanted to see if others felt the same way.

I think I could do 15mm rear but I dont care enough now to switch. The effect on the rear looks less noticeable than the effect on the front, but I think it is because the front bumper tapers off a bit to the nose of the car and shows more tire tread sticking out of the bottom side if you know what I mean. The one effect I don't care for with front spacers is that my front end looks higher than before. It's no different, but since the front rim and tire is in full view from all side angles, the car for some reason looks like there is more finger gap between the top of the tire and the edge of the fender.

But after reading a lot of threads, the only thing I'd recommend against is getting spacers that are thinner than 10. Even a 10 mm spacer might not fit flush against the hub and wheel because of the length of the stock hub. This is also the reason why spacers crack. If a wheel is torqued down on a spacer that's not sitting flush, of course it will be stressed and probably crack after driving.

Thanks for being the guinnea pig. I have been wanting to get spacers but couldn't decide on sizing. Even with measuring I still wasn't sure due to the drop, and if I want to lower it a bit.
