cooltoy- check out this link. this guy has the 20x9 ET32 front like how you wanted and clearing the infiniti akebono.
Vossen CV2
but the thing is, his rear cv2 is 10.5 ET25 and has almost no concavity or lip.
in comparison, this is my gnosis at 10.5 ET25. this is 19" on my G, but check out how much lip
the wheel has and the curve on the spoke. this day and age, you'll want lip or
concavity or both.
