The rim width plays little on brake selection. the offset and diameter play a massive part. However there aren't many options out there, and choosing a brake package will play a massive part on what rims you'll need to run. For example going for 4 piston brembo caliper on the front is going to be difficult to fit under the factory guards as you'll need to run a very agressive offset rim with only a couple a rim chooses. On the other hand if you go for a 4 piston spoon setup you'll be able to choose more rim styles.
Do some homework before buying them though, as it's best to increase rotor size rather than increase caliper size. As increasing caliper size will have little effect over the factory setup.
Can i ask why the plans to do brake upgrade?
Also not a good idea to stagger the tyre widths that much. As this will create understeer. You can never overtyre but you can undertyre a car.
