Fitment nightmare

I don't think I have ever had as much issues fitting a set of wheels on any car than the Z4M

Wheels in question:
18x9.5F, +28, 245/40-18 RS4, I needed a +3 spacer to clear the strut, -2.8 front camber, 0 toe
18x10.5R, +30, 275/35-18 RS4, needed +12 spacer to the back, -2.4 camber

I will not change the wheels, its the numero uno wheel for me for about 15 years, so don't suggest me change better fitting wheels

I have no issues in the rear, its the front
On the track I rub on the bumper, to the point of popping off the sides of the bumper. There is also clear rub marks on the fender liner in the middle both in the front and the back of the fender liner.
I'd like to see if i could eliminate the spacer so it fits slightly further inwards but I had issues with the tires rubbing against the strut, and was told the camber plates on the KW don't shift position of the coilovers i am SOL

If anyone has insights on better fitment, especially for track use i'd like to hear it. To me ideally removing the front spacer

Is the only viable solution go narrower tires?
