I know most people will say stay away from skunk2, but I've never heard anything one way or the other on their camber kits, so I can't tell you for sure on that exact part. I know for lots of stuff though, there are better parts out there than Skunk2, especially engine parts. Ingalls makes some decent stuff, camber kits, etc. I know Ground Control makes camber plates for some cars, not sure if they do your your vehicle.
You will need a camber kit for sure if ypu are wanting to lower your car to right to the top of the fender. As for how low it that? Hard to say, for me 2.1" did the job. I'd have to see your car and measure, but I'd guess 2.5" will be tucked. You could get some good coilovers, that way you can dail in the ride height to your liking. If you are wanting it that low, I'd suggest looking into getting some custom rate springs that are stiffer.
Besides the commen full coilovers like tein that everyone recommends, you can also look inot Ground Control sleeves paired with Koni sports (yellows). The GC's sliup right over the koni's, and it's closer to a fully htreaded body coilover than any other one. It's a very good setup, plus both the GC's and Koni's have a lifetime warrenty to the original purchaser. To me that's worth it. Also, you can order teh GC's with custom rate springs, and custom length springs if you wish. As for the Koni's, the Nuespeed spec Koni Sports (the Koni Yellow SP3's) have a 20mm shorter shaft, stiffer vavling a a 5 way adjustabvle perch versus 3 way.
