I confirm what everyone says about switch to 4s. Much quieter and a better ride. Car handles like new, guess rears were more worn than I thought. My impression is car handles better in my seat of the pants opinion, tho PZero's are supposed to be better!

 

All the journal write-ups I've seen favor the PS4s.

 

+1

And everyone I've interacted with who's moved to PS4s confirm. Admittedly, most people I've talked to have gone to the PS4s on RWD cars, namely M4s, coming from Contis.

My experience with the P-Zeros is only on my RS5, and now about 500 miles on my F-Type, so not very much.

I think it's just a matter of advancing technology.

 

I removed near new Pzero PZ4 from my SVR and went PS4S and the PS4S were vastly superior in every regard.

 

This is the best endorsement rather than after the oem's have worn down and then replaced.

 

Indeed, makes the most fair comparison. I sold the low mileage Pzero's that came with my car to switch to PS4S and 2nd that they are better in every way. Dramatically so. Only now with the lighter battery in the boot and 605 hp tune, I seem to have started to overwhelm even the 4S's in cooler weather. Still wouldn't have it any other way.

 

I switched from the P Zeros within the first couple of weeks to the Michelin Pilot Super Sports, and even they were a massive improvement in traction over the Pirellis.

 

I have PSS4s and they are awesome even better than the MPSS. Much quieter and smoother.
