I have the pro-kits and the AGX's. It's a very good combo IMO. I have it set on 1-front and 2-rear. Though the ride is stiff, it's not harsh or bouncy. If you're really worried about it, just set it to 1 all around. Having the rears set higher does make the rear impact a little harder, but it decreases understeer significantly in corners.

It's a phenomenol handling increase over stock. It makes the car much more fun to drive. I can't imagine what a race-tuned setup must feel like.

I installed them myself, took about 3-4 hours, excluding the time I had to spend having a shop press in new rear lower contol-arm bushings since my old bolts had rusted solid. (Broke a socket, 1 cheap socket wrench, and the head off of the bolt trying to get the damn thing out.)
