Those that have lifts will have changed out there shocks. They should be able to help with an opinion. I agree with Bax though, the shocks are a good aspect of the VX. Some have had trouble, I for one have not (Knock, Knock). I've cavitated other performance shocks (In my sports car) while being on the road only and the VX shocks do exactly what they promise.. They help keep the wheels on the road.
I did notice a ride quality difference when I sold my '99 and started to drive the my '00. I believe it's the lower profile tire albeit on the 18" rims there is much less "Jounce" in the ride. That may open a a new option for you..
