Camber Kit ball-joint or control arm cams?

[TooFast]

I have a 1998 Eagle Talon ES-i. I have installed a tein basic coil over set. I have just ordered the ingalls control arm cam style camber kit for the front. Is this a good kit? The alignment shop I called said I would be better off going with the ball-joint stlye because the last longer. I plan on dropping the car about 2.5". Is ingalls a good kit to use.

I also heard that there is a company that offers an adjustable upper control arm. Is this correct? If so, how does the price compare?

roadraceengineering.com offers a front upper control arm for $480. I've been told it is only needed for extreme drops.
