It's not yet out in the states though so it's only a promise of something good as they can't afford to screw it up. My guess is that you should probably stick with the MPSS for now. Keep an eye on the pressure at the track and that will minimize any greasiness. 35 lbs max right after you come off the hot laps.

Now that's helpful. My first track day with the M2 I set cold temps at about 32 and pretty much left it alone. Noticed definite greasyness as I got faster throughout the weekend but didn't put 2 and 2 together. I'll definitely pay more attention next time. You say 35 hot all around? |
There might be some debate over the exact target number. 35#s or other. Definitely want even temps all around when hot. You'll likely find that if you start at even temps cold then when you come off the track the fronts will be higher than the rears and the left side will be higher than the right since most tracks run clockwise.
