Nothing.
I have auto-crossed the car with absolute domination in the 2L and under stock class at my local autocross club.
I have set 2 hill-climb records with it for the stock class of the Northwest Hillclimb Association.
I have used the car at drivers schools and track days for serious club (Cobra, Viper, Audi, etc.) events and it has NEVER been an embarrassment (oh yeah, I am a performance driving instructor, too). Unfortunately, the 104 MPH speed limiter keeps the fun down. Porterfield carbon-kevlar brake pads took car of the poor stock brakes and have given exceptional service.
I would like to say I don't understand why this fellow thinks the ZX2 hasn't enough power. I just got one, and it flies with the wind! I am about to have installed, a new muffler system which should serve to increase it's performance even more. I guess if you've flown a 707, a ZX2 would prove to be "slow".
Thank you.
Somewhere in the center console you'll find a single green (I believe) wire. Clip it to disable the speed limiter. If I remember correctly the wire is just looped back through the console from the computer.
