After paying attention to all of the constructive criticism on multiple sites, I have finally secured a set of five 15" alloys that clearance the GTi brakes. Sizing is 15" x 6", and is a stock golf/jetta wheel, so offset was not an issue.
I will be using DMack DMG2 tires in a 185/70/15 sizing. Picking up a set of 5, so I will have a spare mounted on board. Keeping my eyes open for another set of wheels, so I can mount a set of snow tires for differing conditions. Probably going to use either Firestone Winterforce, or Hankook tires for those.
While installing the wheels, I also did the wheel stud conversion at the same time. Hardened steel studs, with enough length to allow up to 20mm spacers, if ever needed with different wheel/tire choices.
The first rule of Racecar, is that we do not talk about Racecar.
