Ok so I know the 660 is fairly new.
That being said I’ve run the ps4 on my focus rs for a while and love the tire. This spring I decided to try the 660 on the rx8 as I’ve been using A extreme Summer tire instead of a actual track tire.
So after the first weekend of testing the 660 I can say the grip on the rx8 is amazing. I spent two full days at gratten raceway this past weekend.
Let’s say I was able to really push the car much farther than I thought. It hit a high of 47 so the track temp was cold and still was able to keep a very good amount of grip.
So here is the question. Since it does no good to compare a tire on a awd car to a rwd anyone care to take a stab at how the ps4 would stack up on the rx8? I’m think of trying them next time on the car. They do cost more But I’ve never dared stray away from them on my rs because they seem so good and seem to last.

 

I use the PS4S as my rain tire on my RX-8. They are phenomenal in the rain, but I'll say the breakaway characteristics in the dry are a bit abrupt. I'm told the Continental has better breakaway characteristics and is as good (or slightly better?) in the wet. The PS4S isn't going to hold up as well in dry conditions as the Falken so it would not be my first choice on a racetrack.

 

Awsome thanks that’s what I was wondering it’s very hard to compare a awd car that really goes in the direct you point it as long as your on the gas to a rwd. I may even go to the falcons for my rs next time as I do t drive it in the rain either unless I’m caught in it as a afternoon rain shower in that case just slow down.
