My recommendations are:

1) Choose camber plates for their greater flexibility
2) Start with camber of -2.0° F and -1.5° R
3) Have new tires installed

And, if it works for you financially, get a wider front wheel and tire combination, as our cars are woefully under-tired in the front.

My opinion is that 245s on 9" wheels is the sweet spot; e.g., a square setup with 245/40-17 MPS4S on 17X9s. BMW gave us remarkably narrow wheels given how much power these cars have. If you never lean on the car, of course, you'll never notice this limitation. But that's not what we're about here, is it.

These changes will make a significant difference in how your car responds to your steering inputs. Based upon your photos, and in the absence of an alignment issue, your car has been understeering noticeably since you got it.

I guess I'm driving harder than I thought I will definitely have the alignment checked. If I check and it turns out be within speck, what camber plates do you recommend? I was going to drop the car with dinan springs (open to other options though)... I know they also make camber plates but not sure if their "warranty" applies to that as well. The other options as I understand are vorshlag and ground control? This car is a daily driver so I was trying to avoid camber plates because of the NVH, but if it's what I have to do to avoid having my tires corded then I will get them. Improved steering feel would also be great.

I'm also really interested in a square 245 setup with 17s! Are you currently running that?

Thanks a ton for the reply!
