Camber plates, m3 control arms and pulling the pin on the control arm.

Dinan plates and pulling the pin got me -1.5.

Also running Dinan camber plates and BMWP springs. No rub. I may run an experiment and try swapping my front and rear tires for a day or so to see if it will support the 245/35 up front with no rub. If so I may do buy square next time around for the ability to rotate. However, with the camber plates and the power of this car understeer really isn't an issue and a square setup isn't really required. I just spent last weekend at Road America which has a very large carousel which allows you to really check the ultimate understeer tendency of the car. Frankly the car was quite balanced with my setup.

Any update on this? I'd like to know if I can run a 245/35 on a 8.5" up front. One is it possible, and two, if so what's the magic offset that prevents rub on both strut and fender side. I've read et40 is ever so slightly aggressive where it rubs fender side so I'm thinking et42 + Dinan fixed camber plates should work.

I'm running 18x8.5 ET45 on all four, 245/35/18 Bridgestone Potenza RE050A, ST coilovers.. Have about 1/4 inch gap between tire and spring perch, no rub ever. If I wanted to spin the front down much more i'd probably run into issues with tire/spring perch contact, but I don't really plan to do that.. edit: and oh I forgot, this is just a DD, not a track car so i'm just running the stock 0.48-0.52 camber up front

Thanks, very helpful. I'm looking at 18x8.5 et42, do you think I have 3mm to spare fender side?

Fender rub of course depends on how much you lower and how much camber you run.

As far as the strut side goes, with my 19x8.5 et 42's, I can slide a 3mm Allen head between my wheel and KW strut but not a 4mm. Based on how my rear PSSs look, I'd guess that a 235 PSS would stick out past my 8.5" rim a few mms. I plan to just go with 225s and I'm still a tad concerned that I'll need to add more camber.

I had 235 Toyos for a while and I'd slightly rub at times but back then my suspension was a little lower. For daily driving my understeer problems are not much of an issue. Whereas it is worth trying to run wide rears to stop some of my wheel spin, especially on cold tires.

I'm planning to get 225/40 and 265/35 on 8.5x18 et38 and 9.5x18 et62 and one guy did that with Michelin PSS and exact setup with my plan. His car lowered by BMW PS, so it's about 0.5-0.8" lower compared to sport suspension.

He doesn't rub at all, but I don't know what happens with 19" wheels. It depends on your height as well

Definitely. I've only rubbed once up front on a really big dip.. And the Bridgestones are pretty beefy tires so i'd say you'd be safe with 3mm depending on the tire. I don't have any close-ups but this gives you an idea..

True, I plan on running stock M-sport with Dinan fixed camber of -1.5*. From what I've read, with this setup, an 8.5" et42 with 245/35-18 should be just right with 1-2mm to spare on each side.
