to Vicious for posting this in the "Wheel Spacers 101" thread that is stickied at the top of this forum.
edit: forgot the magic decoder info
Green cells indicate stock wheel poke.
Blue cells indicate flush at stock height.
Yellow cells indicate wheel poke for lowered Z's. Flush at -2 camber rear and -1 camber front is at the highest yellow cell for each given wheel width.
Red cells indicate wheel poke PAST the fender ON A LOWERED Z, I would not recommend any of these sizes. (unless you're going for stance and such, but this post isn't made for you).
