Crew Chief Track Notes & Degradation Profile

At 92°F track surface, thermal degradation is manageable on the Goodyear Hard compound. The tight Turns 1 & 2 hairpin demands heavy trail braking, loading the right-front tire with significant slip angle. Laps 20–25 exhibit a +0.72s pace delta compared to sticker tires.
