To Camber or Not to Camber?

I am trying to dial in the wheel fitment on my Porsche for a perfectly flush look without any rubbing. I don't want the extreme camber, stanced look. Just clean, flush look that I don't have to worry about rubbing on turns or bumps.

I've lowered the car and have adjustable arms where needed to get the alignment dialed in.

Is it possible to run close to no negative camber with flush fitment, or will the wheels/tires contact the fenders when the suspension compresses?

Is it better to base the flush fitment on having a couple degrees of camber so when the suspension compresses, the the wheels/tires go behind the fenders at an angle?

I prefer the look of no camber, but even more than that, I prefer not to make any contact with my fenders. When the suspension compresses, will it naturally pull the wheels in a bit so they don't contact the fenders?

The inner lips of my fenders have been rolled inward but none of the fenders have been pulled outward, which is not something I'm willing to do.

Here's my current fitment with -2.5 camber up front and -2 in the rear. This is the ideal alignment for how I use the car, so I'm either going to compromise by adding spacers, or losing my negative camber.
