Do you think that's damper thing or simply the lowering of .04"?
The same size tyres are used ZCP v non-ZCP.

As the wheels are wider front and rear this means the tyre sidewall is a different shape (the tyres are stretched out more) which makes them feel stiffer - you will notice a slight deterioration in low speed ride quality because of this.

The change in sidewall profile also changes the feel of the steering and the responsiveness to steering inputs.
