Front Wheels rubbing

So I have an m3 competition with 763m wheels 265/35/19 285/30/20 ps4s tyres
With 12mm spacers front and back lowered on eibach springs. So from what I have been able to find is 12mm spacers is common so can’t understand why my front wheels are rubbing at 3/4 lock 3 o’clock side and 9 o’clock side rubbing arch liner is something wrong

I know from recently purchasing tires that the Michelin PS4s in 265/35/19 have [9.6" tread width] across which is why I went with the Michelin PSS 265/35 19s (MO) [9.3" tread width]. I have custom offset wheels which negate the need for spacers and I do not rub at full lock. It also could be your alignment and camber settings, but I am just spit balling. Hope you figure it out.

F80's are known for not having as much clearance in the front as F82's, so tire sizes are more finicky.

Your best bet is to mark where it's rubbing and use a heat gun and some pressure to remold the liner as best you can.

I had this same issue on the same setup. It won't rub if you run 15mm. I ended up getting 255/35/19 for the fronts to address the issue.

So if I go bigger on the spacer your saying it will clear? I want to keep the 265 at the front.

I'm running MPHAS so your results may vary slightly but it should clear. On bumps I do rub the top of the liner though.

I have the same exact tire on my front 437m wheel, which I believe is the same size and offset as the 763m wheel. 19x9" ET29.

My car is at stock, base-M3 ride height and I had the same rubbing in the same spots while running a 12mm spacer. Since the tire is taller, and the PS4S is wider, I suppose it was bound to happen. I think 12mm in front is common and people did not complain about rubbing for a long time because they were running PSS or another tire.

I recently dropped the fronts down to a 10mm spacer. It alleviated most of the rubbing. On very specific circumstances I still can hear slight rubbing but it seems to be a lot less. I plan to log more miles and decide if this is a setup that works for me. I have 10mm spacers all-around and I think it still looks and feels quite good.
