I just got my new wheels in and I have a question.
They are ADR's 17x7 with 48 offset.
Hub size is 73.1
Will I need hubcentric rings for them.
2005 WRX.
thanks,

Stock hub has a 56.1mm hub IIRC, so yes it would be recommended as mounting them centered will be a lot easier. I got mine from Discount Tire Direct and they were a nice aluminum. Plastic will work, but aluminum is nicer if you take the wheels off a lot (I autocross, so I rotate them often).

Thanks for the info...just ordered some polycarbonate rings.
Inner Diameter 56.1mm
Outer Diameter 73.1mm
