Guys.....hold on... This is the OP's 1st track event....he's not going to heat up the tires 8-10psi.
I suggest for your 1st de to start out with the cold psi for the GT3. This will work with the stock alignment settings. As you progress and get faster then you can start to play with alignment and tire pressures...depending on the tire you will be using.

Larry...LOL...before you know it this crowd will have the guy doing all sorts of cheater mods and running Hoosiers for his 1st track event. We don't want to scare him away from the crack out of the gate....let him start to fall on his own then we all can swoop in and spend his money.

That's a good approach. I tracked mine twice before having an alignment/setup done. It was nice to be able to feel the difference. Bar/seats/harnesses is a great way to go. The unexpected benefit is with the harnesses you are held snug and can relax and be lighter on the controls. Makes a big difference.

You definitely DO NOT want to go down. You will hurt the tires. They are not stiff enough to handle low pressures. They also have an issue delaminating if they get too hot. I was warned not to run high psi's for extended periods.
Bear in mind these tires, although pretty good, are definitely 5-7 seconds slower than a good track tire, all things being equal. They drift and howl, but are dual purpose in that they can operate in both environments. Personally I don't care for them on the track after normally running R comps. But they do make for good backup or rain tires.

I just did a test for Michelin on the PSS.. Granted it wasn't in a P car..
But i can tell you the tires is defiantly NOT 7 seconds off of a good track tire.. Or even a Slick!.. Not even on a long track.. I have seen similar performance to a "R comp" like a R888 actually...

We start much lower then 35 and the tires are feeling good before the end of the first lap..

I will say this, I've never met Leh but he is a legend. Somebody told me he crushed some sort of record at Roebling recently. Leh can out drive the crap out of me without a doubt but I bet I whip up on him if he's running SS

It was technically a 2:28.7 if that makes a difference ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Trust me, I was trying! Weird thing about them is when pushed on high speed turns, they drift. I got the crap scared out of me more than once in 1 and 17. Usually you can set a line and hold it with a rcomp. These tires allowed the car to slowly drift out more than planned, slowing down your ability to get back on the gas. It was almost like it was continually skipping a few inches at a time as you tracked through the corner. I slowed it way down after running over the exit curb on 1 a few times in a row.
You were out there that day in your rustang
And I thought you were on SS' too. What times were you knocking down? What did Ian manage on them? He was out there too right?
