Perfect late fall day with temps in the 50s. Ideal for fast times. Was in 58s several times with best being 58.34. First time trying the Nankang CS-R tires-- for a 200 treadwear, they were fantastic. Been running Goodyear Supercar 3Rs, which are 100 TW and are awesome, but wear so quickly. Perhaps that's the cost of getting a sub 58! Can try next year. 

Recent suspension upgrades from Tarrett (see set-up below) really helped straight line braking stability, turn-in and overall balance throughout the corner. Highly recommend them to anyone with a 981 GT4.
