I have recently noticed some strange handling in my S2000. Under acceleration it pulls slightly to the right. Under deceleration it pulls slightly to the left. It is not a very strong force, but is strong enough to notice. It is not related to braking. Tire pressure does not seem to be the problem as they check out ok at 32lbs all around.

Has anyone else noticed this behavior? The car used to be fine.

 

The deceleration part I'm not sure of. However, roads are normally sloped for water to flow off and that could be a factor in the car veering off to the right.
