Hey any of you guys happen to know the specs for this wheel's sizes?

I've got 5x108 and 18x8

Backspacing offset center bore whatnot?

Thanks

2012-2013 Ford Focus
18" x 8" wide
5-lug, 108 mm bolt circle
55mm offset
171mm backspacing

They're now available in black, from Ford Racing:

I have the original (aluminum finish) and would consider selling??????
