I have no idea if this would actually work, but if the FF-1 studs are similar to EA82 wheel studs, we might be in business.
I think original credit for this goes to WJM, but anyway, Nissan and Fuji have been pretty close bedfellows in the past. Nissan has Nismo, which makes nifty little doo-dads like extended wheel studs for running high offset wheels and wheel spacers.
I think WJM was able to use these Nismo studs in his RX, but really, I'm trying to remember this from an internet tidbit almost a decade old.
