Mine ran on the 17's in my sig (Offset ET40) for a few years, no probs with arch work or anything, all standard suspension. And it DIDN'T handle like crap, it does handle better now it has the RA's back on, but I think the suspension plays a massive part in this.
Like Dizzie says, it does look good on the 17's, I'd probably still have mine on, but I've been told I now have no-where to store a spare set of wheels, so the BBS are now back on.
Oh and did I mention that I'm trying to sell the wheels in this pic @ the moment?

*cough, cough*
