If your in a warmer area go with the MPSC .......if it's cool go with the Toyo's...
MPSC are bad when it's cold ....During the spring I wanted to change from the MPSC...now it's realy hot and they work great.

Hi Tom,
I will try 2F and see how that goes...I still have too much understeer (although I like some).
Z06,
My thoughts exactly, if it was Sept. I would have stayed w/ the Toyos.
Thanks,
Jim

Jim: Stock sways? I cheated and used the RS adjustable sways on my 993 to get rid of the understeer and have even bigger adjustables on the 964 (25/22).

Hi Tom,
I was thinking about that .....if I tightened the rear it would help w/ the push and would help with the tire rub also. I will do that when I install new studs this weekend.
Thanks!

I was about a second faster on Toyos, which I attribute to confidence from the increased feedback, but there are always other factors involved, especially temperature. I think my fast lap on the RA-1s it was about 20 degrees cooler outside w/ less humidity.
Anyway, I have bought two sets of Toyos since and won't go back (see my signature).

Are you running full-depth or shaved Toyos?
Thanks for the feedback, the cards are stacking in the Toyo's favor!

I'll never have another set of MPSC's. They're simply too much of a PIA. For me its very simple. Hoosiers for racing and qualifying. Toyos for all other track duty.

It's very easy to get the MPSC's dialed in. Get their handout. In it, they describe the method. I followed it and it worked like a charm. I am going by memory but this is what I remember.
You want 32 front and 36 rear hot pressures. Start with at least 25 front and 28 rear. Go out for 8 or so hot laps and come in the hot pits, jump out and bleed the pressures down to 32/36 if required. Then go out and try again. The next morning check the cold pressures and that should be your starting pressures for that ambient temperature.
After you get the pressures dialed in, get a pyrometer and set up your camber..........
It is a job to get any tire dialed in and you should spend the time doing it. It will pay dividends in both better performance and longer life. Not only that but using a scientific method to achieve your goal makes it much easier, and you will also learn alot about tires and suspension setup.

Nice Mitch, well thought out. and well said as usual.
Don't forget one thing folks, if your car weighs less than 2700lbs you will likely NOT ever get your Cups dialed in and will no doubt spend lots of time spinning.
These tires when cold have little to no feedback and let go with a treacherous abruptness. Ask me how I know!

Also, if I'm not mistaken you're from Florida, so perhaps you've never had the opportunity to drive these tires in cold weather. They are truly frightening in those kinds of conditions, regardless of how you set them up.
