When driving my S2000 on any curve in the road of at least 30-90 degrees at 60mph+ plus, when I hit the throttle, the car wants to "push" straight and does not want to follow the direction of the curve.

Does anyone know what might be causing this?

you're saying it understeers? it should really do the opposite...until you spin into a tree...should really try to avoid hitting the throttle on high velocity turns

The sharpness of a curve is dictated by not only by the degree's of an angle, but the length of the radius as well. You could go 100 mph around a 90 degree turn with a radius of 500 feet. On the other hand, a 90 degree turn with a radius of 50 feet may be taken at 35-45 mph.

How much tread are on your tires? Have you checked the air pressures? What is your alignment set at?

Wouldn't a stiffer front swaybar make it push more?

Um, if the car is understeering the last thing he needs is a stiffer front swaybar.

This is perfectly normal behavior by the way. Increase throttle pushes, decrease throttle and the car will oversteer. Nothing wrong with your car that a good driving school won't fix.

Normal operation. It's too easy to say its the car. It typically isn't unless something is broken.

It's one of two things.
1) Just going into the turn too fast. Not enough grip for front wheels to turn car.
2) More throttle shifts weight to the back off the front wheels, which decreases front wheel grip. i.e. gas = more understeer.

Oh yeah, 2) is not to be confused with power oversteer, where a LOT more throttle is applied to the rear wheels they slip and lose traction causing oversteer.

This is exactly correct. Try going around an on-ramp at a moderate speed. Hold the wheel in the same spot. Hit the gas. You should notice the front end will start heading towards the outside of the corner. Take your foot off the gas and the car will dive towards the inside. This is normal and it is how the car was designed. 90% of the cars on the road will do this.
