Stock offset is 45, but if you change from a 14x6 to 15x7 with the
same offset, then half of the width change goes inboard, and half
goes outboard towards the fender.

Since one inch is 25.4mm, with a stock 45 offset, the 15x7
wheel would be (7-6)/2= 1/2 in = 25.4/2 = 12 mm more inboard.

If you change the offset to 35, then it moves outboard by 45-35 = 10mm
therefore 2mm inboard, and 23mm outboard. There is plenty of
room at the fender lip for this.

The centerbore is critical, but all Audis (and some other cars)
have a 57.06mm (2.25in) centerbore.

No. The 4kq has 4x108. Volkswagens and some very early 4000non-q have 
4x100. Good Luck
