I've got Koni coilovers on my car, with Volk TE37's (16x7.5). I'm
running the 225/40 16's as Chris indicated, with no spacers at all.
Absolutely perfect fit. No rubbing even with a full load at max
compression. I have rolled my fenders a bit, but I don't think they
rubbed before I rolled them either.
