Hey guys, had some time to kill at work, so I made this that should help answer general questions.
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).
How to figure out what size spacer you need to be flush? If you are lowered, look for yellow cells, stock height look for blue cells.
Lets use the stock wheel sizes and suspension. 10 wide et30 for the rear. Find in the chart and you see 97mm of wheel poke. Look for the highest yellow cell in the 10 width. You see is at et5 This means you can fit a 25mm spacer on the stock wheel to reach flush. Do the same for the front, 9 wide et47. To reach flush (et 25) you can use 22mm of spacers.
