You can check my post about the "whats the camber angle" to get more data. I have done a lot of work to get my srt-6 to sit correctly and had to reshim my front springs. The fronts have been off several times so that I could add 1/8" spacers at the top of the spring assembly. It has taken two spacers or a total of 1/4" shims with heavy rubber fiber matting to get up enought height to suit me. I dont want any rubbing and will be autocrossing so I demand a lot, to get it right.
Thanks to Brian's comments I can pull the fronts off in 20 minutes each and add or delete a shim. I shimmed it as I did not know what was going to clear the stock tires in heavy corners. My rim to fender spacing is now 3 3/4" all around which seems correct now. See Brian's posts.The stock eibach are too low in the front and too high in the back so I was getting comfy under my car for a while to get it all figured out. You can see the gallery for more of my photos by clicking on the image of my crossfire engine to get you there easily. Hope this is of interest, let me know.
By the way if you measure from the rim to the fender lip you remove all the errors introduced by the tires, pavement or the inflated height of the tires. It is a really solid way to evaluate the tire height / spacing.
