Im not sure how much detail you want on this but I can provide you some basics.
Front: Fenders are rolled and I run a 12mm spacer. This provides just under a 1/4" of clearance between the shock body and tire. The wheels are 18x9.5 ET35. The tires are 275-35-18 RE71Rs. I run this setup only when Im autocrossing which means i set my camber to about -2.9 degrees so that helps tuck the tires in (camber is backed out -1.9 after every event). I ran this setup last year with the same sized tires but SUR4Gs to test and there was no rubbage. I tested the same setup again but this time with the KMAC offset bushings in the control arm and that increased the track width causing some rubbage with both the and 275 and 265 setups. Once I took the KMACs out, no rubbage. currently running power flex race bushings in the front control and thrust arms...it has been around three years and they are still holding. These bushings prevent alignment deflection which can cause rubbage. Rear: This was much easier. The wheel/tires fit no problem. I was running -2.7/-2.5 degrees in the rear and that was too much...outside of the rears were not heating up enough so I reduced it to around -2.0 on both sides and now the heat distribution is more progressive (optimal grip for longer period of time). I was worried with the new alignment spec that in transitions the rear fenders would make contact with the back tires but that was not the case...thank God!!! The camber and toe bushings are polyurethane so that helps preserve the alignment. The springs are stupid stiff which i need to help control the weight of the car during hard transitions. I'm running 450in/lbs in front and 1200in/lbs out back...this is very aggressive but its part of the equation as to why the fenders don't reach the tires. There's more, but i'll stop here.

turns out 275 wide is very achievable with the F30 platform, just takes some extra work and a staunch ignorance of the naysayers. |

Hi ! I'm using the millway camber plates for 3 years on the nurburgring (about 100 laps) and the alignment is stable. I'm satisfied. I think that top mounts are necessary if you track your car. In the end you will spare tons of money on tyres.

The issue in the rear is that if you ran a 18x9.5 ET23 wheel, it would run against the fender because it would poke out too much. |

Edit: just realized I think I had 245/40/18 tires in the picture. I'm back to the 255 now so they fill a little more than the picture shows. |

Possibly. I think I just need some camber shims and max the positive camber. Then just use the adjustable arms to pull the top of the tire in more and get back to about -2 rear camber. Then I may be able to get the 275 to fit. If I need to do a little extra massaging of the fenders that's ok.
