We're back at Lime Rock Park!! There is a lot of nuance to this track which i was looking forward to working on. I burned up a set of Goodyear Supercar 3R's faster than expected last event so I was forced to run my Falken RT660 autocross tires on the track. These tires had one autocross day on them. After 2 sessions I felt a terrible vibration... inner edge of the rears delaminated in 3 spots. No curb strikes or anything, just failed due to being driven hard. Never run these tires on the track even though they are marketed as a track tire.
