“OK. PSS vs. PS4S. I used both of these on my 2011 GT500. In general the PS4S is an modest upgrade over the PSS. Slightly better dry grip. Bigger improvement in wet grip. Better grip when not warmed up yet. I did not that the PS4S is more sensitive to very cold (below freezing) temperatures, so I put the GT500 away a little sooner for winter. For my GT350, I switched to the A/S 3+ (275/35/R19 front, 285/35/R19 rear) and have been really liking them. I am sure they are slower on a track, but on the street they just grip and scoot on corners or straight aways (slightly less grip on a hard launch - but haven't tried launch control yet). It is very nice not having to worry about rain or cold. Still plan to put her in storage before the first snow to avoid the salt.”
