Then you should know the tire size is equally important. 19x10 is nothing if your tire is small enough 
I'd expect stock tire diameter to easily allow the 10" wide rim. Yours may be a little "stretched" too? Tell us the tire size and post a photo!
He's planning to use a 26.75" tire diameter. 245/35x20. I'm running the same diameter and have virtually zero fender liner clearance left to increase size. Mine don't rub, but would if I went up another step.
It's going to depend entirely on that m5 fender liner shape.
I'm very interested to see some photos upon test fitting with the wheel turned and maybe a test with the wheel up onto a curb cut a little to mimic cornering compression.
It'll be good information for those looking to max out the tire size.

Before swapping to the 20" wheels, I decided to replace my front thrust arm bushings. This is incredibly important for the health of your suspension, braking, and the longevity of your tires. An easy way to tell if your bushings are bad is if you hit the brake decently hard while going 5-10mph and you feel a jolt in the steering. You can also feel it if you go over a speed bump or in to a driveway and the suspension feels loose (sorry that's the best way I know to describe it.
Easiest way to figure this out is to get your car on a lift or even a jack and if you can move the front wheels side to side, you need new bushings. Uneven tire wear is a symptom, though that can be caused by improper alignment.
Here's a comparison between new and old:
You can see here that I should NOT be able to separate the rubber from the metal. This is showing that the rubber is old and torn internally. Sorry it's hard to photograph.
More to come...
