Hi I've Done a hatch K-swap. I'm lokking to buty a set of new wheels, wider wheels. I have Buddyclub p1 15x7 4x100 Et : 42. I found 16x8 4x100 +38 will they rub? With the buddy's it isn't rubbing with 2 deg negative camber. Can you help me if someone have or know about this.

16x8 4x100 +38 isn't enough info. There's much more to consider including:
tire size
ride height
rolled fenders

But yes a 16x8 +38 could work if the other things above are just right.

Also if you're doing it for performance/traction purposes, stick with a 15" rim for better tire choices and a 15" tire will also have less chance of rubbing than a 16" tire.

thanks. it's lowered like 3/4 of a cm from tire to fender becuase of sump (23 inches from ground to fender), Running on 195/55/R15 bridgestone Potenza RE01. no rolled fenders yet. I Want traction, it's spinning till 3rd then it grips. this is the first one in Malta (EU) so I need a bit of help please.

A higher performance softer/stickier tire will perform better than a wider tire, even if the high performance tire has less of a footprint width.
