it will be largely down to the springs and tyres used.
on my 17" Bridgestones running factory MK5 GTI suspension, I tend to find the car a little crashy and hard on the road.
On Pirelli Nero Rosso's, I found the car buttery smooth, grip a plenty and drove they way I thought it always should have.
If your car has been lowered, find out what springs, Otherwise go back to stock springs it will help some.
Lastly, try the likes of Toyo proxies 4. They should give you your supple ride you are after.
