Nice lap. I'm hoping to participate in Seat Time this year. I know you have to be in the advance group in SCCA to be approved and I missed the event last weekend to move up. I was a flagger at the last SCCA event at Jefferson and missed the chance to talk to you. Hope to see you out there later this year.
Open track day (Seat Time) at Summit Point last October on 315/30R18 Conti ECF. It's been a very consistent tire and very heat/pressure tolerant. In this video, the tires have ~12 track days at 3 different tracks and ~800 street miles. They're great lapping tires if you're not looking for a PB. The ECF is 2-3 seconds off my GY SC 3R times.
