Good race. I was affiliated with the BFG/Busby GTP Team in the 80s, fielding 2 Porsche 956/962s, after years running a non-competitive Lola T616, and always enjoyed Daytona and Sebring, along with the other IMSA tracks.
I remember the Busby Team. I saw them race many times. I used to live in Florida and went to Daytona and Sebring every year even when the final race was a 3-hour race at Daytona. Also went to other IMSA races in Tampa, Ft Lauderdale and Miami.
