What is Bushing Compliance or Deflection?
In short, compliance is a bushings tendency to allow movement due to the force applied to it. Thus it is complying with the force and direction exerted upon it. The bushing can also distort from the twisting motion of normal suspension movement. Generally, compliance and deflection are bad because they do not allow your cars suspension system to work positively 100% of the time. Poly bushings are designed to hold their shape, resisting compliance under load much better than the OEM rubber parts. This reduced bushing deflection helps maintain a more precise suspension geometry resulting in improved handling.
