Hey man, no bounciness at all.
The stock svt suspension damped very well on the freeway, but this is even better.
the springs look like the rate is progressive, so it gives a compliant ride but also has the stiffness to resist bouncing in dips. The shocks damp out everything well, so there isn't any rebound either.
It does have a tad more harshness on really rough road than stock svt, but overall trade off is sooo much better.
