I'm on TEIN Flex Z's also, nothing to complain about. I lowered it pretty conservatively with a teeny tiny bit of camber (3 finger gap in the rear and 2 finger up front) because of how shitty handling gets when really low. I've got Buddy Club RCA's to help with that as well. Running a fat rear sway bar with the stock front bar to try to bring the steering response a little more neutral (there's this one turn on my way home from work that if I gun it I used to understeer like a MF, but now not so much, even broke traction on the rears when I had my bald tires still).
