hi,

I recently bought a 2003 BOSS, the chrome on the wheels is bad so I want to put new ones on in black, I have been searching the net for the offset of the standard 20x9 rims but I can't seem to find that info, I would like to stick to the 9" up front and go to 10 or 10.5 in the rear, maybe drop the suspention in the future but I do not want any rubbing so I need to calculate what to fit, all help is welcome

Greetz, mando
