Hi..i already installed wayta cushion buffer as i received the package last week.
First off the installation is quite easy compared to amt buffer (installed on another car) due to its softness.

What i noticed is the knocking sound from my rear absorber has been eliminated, or i would say not so noticeable compared to before installing. Handling had been so much better, when going through uneven or bumpy road,the absorbing ability also improved as i'm using sport absorber.

So far i'm satisfied with this product.
