As camber bolt kits go, this is a good kit, but it does not operate the way a $400 caster-camber plate like Vorshlag's plate works. These bolt to the spindle and adjust camber that way. It's certainly one way to go about it.
In my opinion, it all depends on what you want. I personally don't feel that strut tower mounted cc-plates are needed unless you're doing serious open track work. I have GT500 mounts and no camber bolts on my own car. It's at -1.7° camber and it works well that way.
I've never seen those before. I assume they have to be a step up from the standard 'single bolt' system used? What kind of spring drop do you think those are good too? I wanted to do the Eibach 1.6/2.0 drop but didn't think a bolt system on the strut would work with that type of drop.
