12mm BMS Spacers rubbing on stock setup. - BMW 1 Series Coupe Forum / 1 Series Convertible Forum (1M / tii / 135i / 128i / Coupe / Cabrio / Hatchback) (BMW E82 E88 128i 130i 135i)

So I installed 12mm BMS rear spacers yesterday as I probably won't be picking up new rims this season. I'm running a stock 2011 m sport suspension/rim setup and (sadly) the Bridgestone RFT 245/40/18 tire. Looks great, but oddly enough only the right rear tire is rubbing. It's bad over humps or taking a sharp left turn and I need to figure out a fix. The rub even happens at low speeds.

I don't want to have to get my fenders rolled as I thought that 12mm was definitely playing it safe as I'm not lowered.

Is anyone else running this setup with no problems? Any idea why only my right rear is rubbing (even when I'm the only passenger)? I emailed Terry @ BMS too and I'm waiting to hear back.

Thanks guys,
J

That's quite strange. I'm running BMW 15mm spacers on all 4 corners with stock Msport suspension and i have zero rubbing. I have hankook ventus v12 evo's in stock sizes, though they looks to run larger than the stock RFT's so i don't think that is an issue.

Is it rubbing on the fender lining? or on the fender itself? or someplace inside that you can't quite tell?

You could try and get a little more negative camber dialed in the rear, but honestly, what's the big deal with rolling your fenders? It's cheap and works.

I had this with 255's on the back. I swapped to 10mm rear (since I'm dropping it anyway) and no more issues, even with a car full of parts, chicks or guys.

First, you need to determine what exactly is the tire rubbing. I doubt you are rubbing the fender (unless you had body work done before)... Fender/wheel well liner is most likely what you are rubbing. Some times, the liner just need a good tug or something that makes it stay high.

People freak out when a known working setup rubs without proper diagnostic

IMO, your tire is hitting the liner, not the fender. If you jack the rear of the car up a bit, you may be able to poke around in there and check out the condition of the liner with a flashlight just by decompressing the suspension and not taking the car completely off the ground.

Yea i am sure it is the liner. It will rub less when you have a half tank and less (obviously). Happens to me but i run an 265/30/19x10 though

Joeyb7 · 04-24-2013, 08:45 PM

So if its the liner rather than the fender what's the solution? If others aren't experiencing any rub at all is it because they've modified their liner?

Rocmit · 04-25-2013, 12:00 AM

Find out first! I don't think people here modified theirs. Rubbing it or not depends on how low the liner sags.

Most people probably ignored it after they knew what the issue was.

Solution could be as simple as tugging it in better, if it comes off fender railing. I thought of using double sided tape on the back side of liner to make it stick to the top (but i didn't do it). It all depends on your situation.

Joeyb7 · 04-28-2013, 08:59 AM

So I diagnosed the rub with some tape even after swapping to 10mm and the worst rub is at about 3:00 if you're looking at the wheel. It's the area where the front fender starts to be wider...I was surprised to find our that I'm actually hitting the fender. I also read that having a rub on the right rear and not the left is most common. I came across a few threads where others asked their techs about this an they said that it's due to a slight 3mm axle offset on the right side. Whether or not it's true I don't know, but it seems that my right rear rub issue is fairly common.
