18x9 wheels
Does anyone know if a 9" wide wheel will fit in the front of a 135? I have a set of 18x8 40mm offset OZ ultraleggara wheels for track use for my E46M3 that i am wondering if they will fit a 135.

Can you list the Offsets for the 8.5 fronts and the 10" rears that will fit? (stock height) thanks, Gary

I have to look up what measurements I have for the front. We run 18x10 in the front so I don't have offsets off the top of my head for 8.5.
We did run 18x8.5 front before, however those wheels were loaner wheels from Forgeline and they did not rub at all. We run 18x10 +62 in the rear We're getting a slight rub on the inside wheel well plastic. Ideally I think maybe a +57-60 and roll the fender would be best |

We test fit a set of 18x9" (ET41 D-Force LTW5) onto a customers 135i recently. Seemed to work fine to me... :iono: Any car this heavy needs as much tire as you can possibly stuff underneath it. The rear can handle more than a 9", but then you're going back to a staggered set-up which means more understeer. BMWs work best with the same wheel/tire widths front and rear. The 18x9 wheel on the back of this car would have worked better with more backspacing, pushing the wheel inboard more. From my testing, I think an 18x9 ET45 to ET48 offset would be ideal out back (and the same set-up with a 10mm spacer up front would make tire rotations easy). An 8" wheel should fit with ease. That's still too narrow, but it would work. Anything to get the boat anchor factory wheels + run flat tires off these cars is a good thing. 48.3 pounds for the OEM front wheel + a replacement tire, and that's not even a run flat (which are even heavier, and ride/handle worse). That is abysmal for such a skinny wheel and tire. Those brakes are also MASSIVELY heavy. Its no wonder why these cars push 3450 pounds... but it can be fixed. |

Now test them it on an auto X course at full tilt and we will have a clearer picture.........:biggrin:
They look great. How much camber? Stock suspension otherwise? |

I have the same wheels in 17x9, same offset, 5mm spacer (just as pictured). I am lowered, but I did need a slight inside lip roll. I have done about 120 autocross runs with that setup in my 135i. 245/40/17 Star Specs.

The car got more track time this weekend with the run-flats and the stock pads. No other instructor was on run flats; but, the car held its own fairly well and unlike the last time I had the skid pad, I was able to turn that DTC off through holding down the switch for 5 seconds. Wet skid pad, the car is very neutral certainly not the dry characteristic.

You should be able to run clost to -3 of camber up front with a good set of camber/caster plates such as Vorshlag or TC Kline. If not, get yourself a set of the E9X M3 front lower arms for an added -0.75 of camber, better bushing(a solid joint in this case), and a slightly better geometry.

I'll be able to run -3.25*, maybe a little more, up front and will run around -2.5 to -2.75 out back.

What tire.. because 255 z2ss are at the limit of driveability for me with the same width and offsets. Perhaps a narrower 265 would fit similarly but I could not go up a size on the same tire. I'm at -3 front, -2.2 rear. Plus I feel that there is very high diminishing return from going 265 over 255 on a 9 inch wheel

265 is not going to work up front very well.
I have a 255 RE71R (wide tire) on a 9" wide wheel with a +35 offset (which is the absolute highest that will clear the strut with this tire) and it just BARELY fits, and rubs over extreme bumps. I have -3.6 degrees camber with the M arms and plates. -Mark

That will help. My fenders are stock and rolled but not pulled out at all.

I haven't done much research on them but the source of rub is usually at the front tip of the fender where it meets the bumper on stock fenders. If the n5tuner fenders taper to meet the stock bumper I fear those may encounter the same rub.

I'm trying to decide between OEM 1M parts up front and aftermarket. I just wonder how odd the rear would look with the 1M front track being so wide (kinda like reverse rake)
