IMSA is great. I loved watching it at Lime Rock.
It is. Back in the early 80s, I drove BFG’s Porsche 962 doing tire testing, at Daytona, The Glen, Mid-Ohio, Laguna Seca, Road Atlanta, Lime Rock, Sebring, etc. I had a Class C SCCA license and couldn’t drive in wheel-to-wheel competition, but could do 180-200mph tire tests. Most fun I’ve had with my clothes on... lol.
