Wheel fitment?

Looking to fit 255/35r18 on 18x8.5 et35 on a 2001 330ci. Currently at 3deg negative camber front and 2 deg negative camber rear on coilovers/full adjustable suspension dropped about an inch and a half. Sitting on 225/40r18 and 255/35r18 with 5 series wheels now and seem to have about a half inch gap before hitting the fenders

Don't have much experience about slammed cars, don't see them here.

I am however very curious about a couple of things with respect to the wheel alignment:
The left rear camber; Before adjustment it was (!) -11.5 Really?? (seems impossible.)
Left rear toe; Before adjustment +6.10 Really.

The final numbers look pretty good, albeit you might have egregious wear with that much final rear toe?

What is bothering me are some of the secondary measurements:
There's a huge disparity left/right of SAI. Why?
The video (below) talks about what SAI is. The part about positive camber (@35 seconds) applies to FWD cars and should be ignored.

I guess I'm just a little astonished by what I feel are just about untenable angles. When was the last time that alignment machine was calibrated? Not trying to stir a hornet's nest, but I have a hard time with what I see in your report.
How does the car behave on irregular surfaces in an exit ramp?

I do a ton of wheel alignments here and fix issues that other shops have done with respect to alignments. I've never in all my years seen numbers like that, unless the primary measurement was done w/o springs in the car?

Well the first measurement was done after replacing the stock suspension with the coilovers, rear camber arms, rtab/limiters, installing full poly/derlin bushings, new tie rods, basically everything. Tried to eyeball it but things never come out perfect that way. Also this car is meant to be strictly for tearing up backroads/track driving so tire wear is the cost of admission for it feeling perfect
