The Federal's disappointed at the track. They might work better as an autocross tire than a road course tire. Straight line acceleration is improved, and so is operating temps, but they do not hold lateral g's the way Hankook RS3's did. The Federal's have good value in cheap fun, but next time around I'll spend the extra coin.
Max G's I pulled at Lime Rock was 1.0 and holding .9x. RS3's would regularly hold 1.1x and peak 1.2-1.3 g's. Best laps were in the 1:09 range. I had more confidence in the steady state grip of MPSS.
I have pics, video, and data to upload when I get a chance. Another thing to note was that I never even came close to the scrub bar. I had bled all the way down to 28psi/26psi cold coming off at around 36psi hot and the tires were still way above the wear bar (-2.0/-1.7* camber). Things improved throughout the day the more I bled the tires down. This must be a function of the rounded sidewall and the lack of lateral grip? Can't say I wasn't pushing it...
