the ET won't tell you. Sad to say only most 17s do not give you sufficient clearance (I ended up having disks cutom made). Only way you'll find out (or at least the only way I can tell you) is if you can get one of the alloys and physically mount it on your car, then measure your clearance from the inside of the spokes to the disk surface. I can tell you then (once I unearth all my papers) if your in luck or not.
