No problem. Attached is a worksheet obtained from Orb that has pretty accurate assumptions. All of the calculations are validated and based off of Milliken's work. Since you can't attach excel doc's, just right click and save target, then right click the icon and "open with excel".

I would not advise this at all, lol.
There can be a few reasons for not being able to get additional negative camber. If you are using OEM shaped springs (like what comes with all xi coilover kits, except AST and HPA Swift conversion) then it is likely the large diameter of the top of the spring and spring perch is preventing anymore negative camber. If you do have 60mm springs, then further investigation may be needed.
Also, depending on your current spring rates and suspension choices, you may be getting excessive understeer.
