Have offset and can fit wheels with different PCD as well. Seems like a good thing for me.
Nice stuff. Will not be much of a problem to the car right? Last time Izso mentioned spacers are not that good.
Problems will spacers is they just push the wheels out. If too thick means your lug nut will have less amount of turns on the screw, unless you change to longer ones. Another is most spacer do not have center cone.
For adapter spacer, your offset will come out a lot. Unless you can counter with rims offset....
