Consider the 1.75" UCA drop. Actually provides a better camber curve, but necessitates the "negative wedge" under the upper ball joint.
I've driven cars with all the various mods. I'm personally doing the GT springs cut for lowering (rough roads around here, the 620's would kill me, remember they are like twice as stiff as stock), a 1" sway bar, 1.75" UCA drop, all new joints etc., KYB's, and getting the best tire I can fit. Should provide a non-jarring, flat, better handling ride.
Good luck!
