The best thing you could do for your set up is get rid of the kook's. They suck and then suck some more. If you are stuck with the kook's for a while they like lots of camber and lower pressures. They have soft side walls but don't respond well to higher pressures. Start with 32-34psi and -3 degrees camber in the front and adust the rear camber to how you like your car to rotate.
Marcus. I know you don't like your 'kooks but damn. I think they are a very good tire and an excellent value for the money. Nothing short of an r-comp will have the sidewall stiffness of the RE070s. I have my shaved 'kooks that get put on my WRX for autocross. I will be running stock shocks with STi springs and 26mm front Whiteline bar and 24mm rear Whiteline bar with MRT front camber plates. I am thinking -3 degrees camber front, -1.7 rear with zero toe all the way around.
Yeah, I am still convinced they suck. Shaved they will probably work better. I don't think they have as good lateral grip as the rt215 nor are they as predictable. With the prices the rt615 is going for on vulcan tire the only reason I could see running kook's is if you are sponsored by them.
OT: If it makes you feel any better, I will be running my 225s to start the season, so you can compare to stock 'dead' (or as I like to call them -- race depth) RE070s to your Kooks.
KA Comment: I guess I like more rate as opposed to more bar is it feels like two different ways to drive the car. With a big bar, to me, it feels like the car has a huge inital reaction to a little input with varying reaction. With a smaller (read: stock) rear bar and more rear spring, the car feels like it has a much more progressive response to your increasing steering input -- i.e. much more linear and controllable. The down side is you are stuck with a car that does NOT like DD bumpy stuff, hence finding a good medium (and I have high tolerances). None the less, go drive a go kart and then get in your car. It feels like a Lexus afterwards.
Overall: If you are going to jump in, I say jump in. Choose specific things you wanna change, change them, and LET IT SIT FOR 2 AUTOXES. Then, adjust as necessary UNLESS it is really wrong (-3.9f/+.5r on 550/500 rates was WRONG).
Doooo eeeeiiit! (and ride in our cars at the test and tune to get a feel for differently setup WRXes [STis are WRXii]).
