Auto Cross 1g Setup

[Kracka]

The 2-piston front calipers should be ok, just get some nice pads for them and use quality rotors. You should definitely think about adding at least a rear anti-sway bar to your suspension setup. The Evo III 16G would be right at home on the autocross course. The RX-7 wheels would be nice b/c you can easily put some wider tires on there; get something decently sticky with a stiff sidewall.
