Yeah, the right offset definitely helps - my 15x7.0's rub the wheel balancing weights against my struts (although I do think the wrong sort of wheel weights have been used).

Um, these are fat 15's. Need 2 spacers to clear the shocks up front, and probable 30mm flare. Rears need no spacers, but still some flare. And yes I know you can only legally alter track by 5% or something, but thats a risk I'm willing to take. Cops can see rubber outside of guards, but they're not so good at maths.

How fat is fat? If you're going more than 7-inches wide then it may be a tad wider than what you really need. Surely they're no greater then 8-inches.
