Actually i think that I have read that some people even run spacers with the 4 fronts, which means that you would need thick reasonably spacers for rear rims.
Hi,
I don't know for sure how the 16 inchers fit, but unless you have a set laying around, or just like the appearance of these wheels, I would explore the aftermarket possibilities.Lots of options out there. Have fun!
Rears up front....
Do a search, i know a guy who did it.. 7/16 spacer and deep shank lug nuts on stock front rotors..
Neil Werner ran them on his daily, surely its posted here...
