I found the stock PS2 19" had very good grip at the track...BUT the shoulder wear is concerning...& I was coming off the track at about 43.5psi hot..about 34.5 cold.....my tire temps were between 160-180F hot....the front tires really chewed up the outside shoulder...the little design on the shoulder is GONE..on both front tires....the rears actually look pretty good, but I also ran with MDM all day so I wasn't spinning them too much :>)

I would guess they wouldn't last more than a few more track days at best before cording the shoulder...
