You are probably dropped pretty low right? And I assume you want a kit to apply some positive camber? I would first get a general idea of where its at now, where you want it to be, find the difference that it needs to be corrected, and there is your answer.
On the street I'd probably run about -1 to -1.5. If you are at -3, you need something that can apply +1.5 camber.
