UPR Shark steel caster/camber plates?

Anyone running these? For 100.00 is looks like a good deal.

I was looking into those awhile back and everybody seemed to be down on those. I still haven't gotten a set of c/c plates only cause there doesn't seem to be any negative tire wear. Oh and I have Eibach sportlines like you.
 
Don't forget that the entire forces and stress from your front end is going to lay into these plates.

mm... is the way to go.

And not just "sound" but quiet too...
