Mate I haven't ordered the wheels yet - although with the exchange rate at the moment I could put the savings towards rolling the guards. My priority is to fire the engine before xmas so the wheels can wait.

I couldn't put a figure on how much the rim or tyre edge would move inboard, but I know Whiteline sell lots of kits for the R32/R33, so perhaps give them a call? If you're handy with a ruler and protractor (or CAD software) you could probably draw it to scale and compare various setups.

Just a thought... those adjustable arms may solve your clearance issues, but will the resultant camber angle be too aggressive for the Harrison? Eg, uneven tyre wear, poor traction or bad dynamics on the race track.

Thinking outside the square... can any material be milled off the bolt up face of those Dragways? Or would a slightly lower profile tyre give less bulge and still look/drive OK?
