This is the wheels I want. 20x12 in the back and 19x8 in the front.

the website http://www.xoluxurywheels.com/album/verona/ does not show the backspacing options but in the gallery of cars they have them on the new cameros and corvettes and mustangs.

Im wondering would these fit my 2000 formula? or what questions will I need to ask the company?
