You dont notice it too much as a driver. Sure you'll feel the potholes and speed bumps a little more (you'll have to take them slower too) but it isnt a "oh my god thats awful". Of course this is purely subjective so I might be wrong

As a passenger you notice it a lot. I used to whinge about the ride in Rally Slag, noticing the difference between our cars, til I got mine done and hardly noticed it. Handling improves ten fold too.
