P.S. if you run the Macan calipers, you can use the 340mm discs..however the 345mm discs will require the discs splash shield to have the lip bent out of trimmed off..
Plus you can run 18inch & in some cases 17inch alloys...some aftermarket ones at 45et without spacers, & some with...all depends on the spokes being dished outwards or inwards...
