Especially in the front you won't have a heck of a lot of adjustment for camber with the adjustable LCAs. The problem is that you can only lengthen the tie rod so far before you run out of threads. If you were to do camber plates in the front the noise wouldn't be inside the cabin, which might be better than in the rear where it is right behind your head. Plus John says the EMI plates that he sells don't make noise, so maybe try his first.
I think that trying to adjust camber with the LCAs is not the best idea. Our chasses are usually not straight so rarely would you end up moving the control arms the same amount, so then you have one wheel which sticks out further than the others to adjust camber, and you're still really limited in the front due to the tie rods.
