High Speed Stability

Not the answer. Many folks have run their cars successfully without a wing. The NASA National TTC winner was an S2000 owner... without a wing. 
Stock suspension? Lowered? Alignment? Tire pressures? My guess is rear toe is not "in" enough.

I have a stock suspension. The car has not been aligned since I have owned it. Tire pressures are 34 psi front, 32 psi rear cold, checked before every use.
i have a 03 ap1(on stock ap1 rims) and i just got tein s-tech springs because i could feel alittle body roll from my stock springs. but i like to kick the backend out as much as i like speeding around some corners lol
Like everyone else said, you need a fresh alingment. What settings to use? Thats up to you... (Id either go with stock or UK settings)
Also id strongly suggest getting correct tire sizes on your car.

about the alignment comments I also want to point out the the smaller steering ratio found in AP1's.(and S2K's for that matter) The AP1 has very responsive steering and most drivers immediately comment on how precise it is. You can definitely notice a difference driving one on the highway. Where in a normal car you might turn the wheel left to right slightly and the car wont move, however in the S you turn the wheel ever so slightly and the car actually moves!
I could see this becoming more apparent if you are driving fast and your inputs are not perfectly smooth. Features like dynamic steering are found on more and more cars today. This gives the driver quick turning and a smaller turning ratio at low speed but a higher steering ratio at higher speeds so highway driving is more comfortable and you don't feel like you are fighting the car. An F1 car can steer lock to lock by maybe turning the wheel a half turn each way. The less you actually have to turn the wheel is definitely more desired in a race car.
I think most would agree that the S drives much different that pretty much any other car and if you are still a new driver to the car it will take some time to get used to how responsive the car is and to be comfortable predicting how the car will react.
AP2's had revision made to make the car less twitchy and more "stable".
