There's definitely a little bounce (feels like up front) when the road has a bump or two. Vertical motion then little aftershocks as it were. That's the best way I can describe it.When you said 'bouncy' that means (to me) up and down motion of the suspension. If that is happening, something is wrong. If the G8's ride feels edgy like over seams and sharp transitions in the pavement, that is what us PPV users have experienced and will decrease with break-in miles. As mentioned - new springs do settle in but should be minimal with quality products.
