Having had a MY16 on standard suspension 20" and now a MY17 with air and 21" wheels with the Pirelli PNCS, there is a significant improvement in terms of noise reduction between the 2. However the biggest improvement in terms of noise and refinement has been fitting 19" wheels.
I was suprised how much the ride and refinement improved when I fitted them, don't get me wrong there is still road noise on rough or poor surfaces but it's a noticeable difference. I did feel the air suspension a little coarse on the b roads I normally drive with the 21's, but with the 19" fitted it floats along like I had hoped it would. Even the wife noticed the improvement so it must be obvious!
