I've put a handful of miles on the new SO4s. So far, they are really quiet, much quieter than the wornass Advans that were on it. The Z seems like a totally different car with that awful drone gone.

They have more grip too...but not like you would think. I don't do any corner-carving on the street. However, I could slide the front Advans simply by turning the steering wheel past halfway at a stop and taking off normally. The SO4s will not slide.

I'm perfectly happy with them at this point. I just hope they continue to be good tires as they wear in.

I got them from a locally owned auto service for about 1300 out the door.
