You need rims that have about 20-28mm offset, a 57.1mm center bore, and bolt holes spaced at 4x100mm. Spacers can solve some of the offset and center bore issues, but require longer than stock lug bolts. The first option that I saw at the link to the Helo wheels was 16" with a 76-something bore and 42mm offset. That would require 15mm hubcentric spacers and lug bolts 15mm longer than stock.

this link for another option - great price, nice looking wheel, deep dish, light weight, proper spacing, bore and bolt pattern. Makes me wish I hadn't bought the BBS RX wheels last fall...
