New wheel outer face already out 20mm more compared to stock . Run just enough spacer required to clear, 3 to 5 mm. Do you have a BBK?Forgot to ask, but wasn't the stock offset for your 19 GTI +49? If so, might need thicker spacers since with new wheels you lost 7 mm.
they are BARLEY touching, would shaving the calipers a bit do the job as well?Yes, spacers are needed, but with spacers longer wheel bolts will be needed also. How bad does is hit the calipers? Probably needed at least a 10 mm spacers and therefore 10 mm longer wheel bolts. Be sure to get the correct wheel bolts for the the wheels, ball seat or conical seat. What wheels did you get?
I have TTS calipers. Outer face maybe out 20mm farther, but it says nothing about how the spokes of the wheel are. Do they curve inward compared to stock or outward? I have 18x8 45et Neuspeed RS forged wheels and the spokes curve outward. Did not need spacers with the stock PP calipers with these wheels or the stock Nogaros.New wheel outer face already out 20mm more compared to stock .

No, please don't shave the caliper or wheel. The metal is there for good reason. Your best bet are to find wheels that fit or spacers. For test fitting only you can use washers to the measure for spacer clearance, but measuring with a template would be your best bet
