What's going on, trying to see if anyone has been successful running 255 squared on their stock body 135i.

Running 3 degrees of camber all around or just the front?

I'm running a square setup of 255-35-18 RE71r on 8.5" ET52 style 264s. I have a spacer at the front to get ET40.

I've rolled and slightly pulled the front fenders, as well as trimmed down a fair amount of the bumper tab. With -2.0 degrees of camber and at the stock height on the base suspension, I still rub at what's left of the bumper tab at medium/high compression.

Getting 255-40-17 on the appropriate 17x9s (they are pinched on an 8.5 - they are barely square on a 9") on the front of a stock fendered 1 series is possible but requires all the pieces to be perfect.

You need coilovers with short springs above the tire, camber plates (set at max negative camber, for sure more than 2.5 degrees negative), and a perfect offset wheel (for a 9", around +35). With those things, the 255s will fit perfectly. Adding the 1M arms will make it harder to clear and will have it rub under some circumstances.

I have gone through this exact process on my 128 and have tested the above thoroughly. Below is a photo of my car with 17x9 +35F, +50R with 255-40-17 RE71Rs WITH max camber plates and M arms. It rubs. Before the arms it was perfect, but the car is faster with the extra camber from the arms (-3.6 instead of -2.8) so I tolerated the rubbing.

No but the offset was perfect, tire about 3mm from strut. Our car was also not quite as low as Mark's shown above, exact same setup otherwise.

Fitment looks great Mark! Do you think a spacer would help the rubbing on the m arms?

You are misunderstanding - it rubs the fender after the addition of the M arms. A spacer would make this worse. The very best possible fitment would be camber plates set to maximum negative camber and stock lower arms (which keep the tire inboard) but that would produce less negative camber overall than adding the M arms.

And to be clear - the setup in that photo rubs in a variety of scenarios. I considered it barely viable for racing purposes and it would have driven me mental on a street car.

I hope you fully understand your car is no longer STX legal.

Camber plates, -3 or more up front, 18x9 +42 and you can do 255 or 265s all around.
Biggest factor for front fitment will be getting your spring perch above the top of the tire, which will likely mean removing the helper on your coilovers up front.

To be clear - I had stock arms with offset bushings to simulate the length of M arms. I just say "M arms" for other people as literally nobody other than an STX competitor would ever choose offset bushings over just buying the arms.

I don't even own the car anymore regardless.

When I ran a 135i I was using 255's square. Had M arm's up front with -3.2* of camber. This was with stock 264 style wheels (8.5's all around ET52).

The rear is easy to fit 255 or larger, the problem area is up front. Get enough negative camber and the right offset wheel and you can do 255's fairly easily.
