Sebring, FL — As Historic Sportscar Racing readies for its season-opening Spring Fling at Sebring International Raceway, it has adjusted the schedule to run from Wednesday, March 31 though Friday, April 2 so that competitors and fans can take in the full event and still be home for the Easter holiday weekend. The early entry discount deadline is March 17.
The HSR Spring Fling includes the first 2021 rounds of the B.R.M. Chronographes Endurance Challenge in a special Friday doubleheader schedule. The one-hour Vintage and GT Classic (GTC) B.R.M. Endurance Challenge kicks off Friday’s schedule at 8:30 a.m. EST. The opening race will be followed by the Historic, Prototype and GT Modern (GTM) 60-minute endurance challenge at 1 p.m. EST that afternoon.

The WeatherTech Sprint Series is another highlight of the HSR Spring Fling schedule with the usual twin race lineup bolstered by a third bonus race on Friday. After Thursday’s first round of WeatherTech Sprints, two more races will be run for all Groups on Friday.
The event schedule also includes back-to-back feature races closing out Thursday’s on-track activity. The Sasco Sports International/American Challenge race goes green Thursday at 3:30 p.m. EST and will be followed at 4 p.m. EST by the HSR Stoner Car Care Global GT race. Get the full provisional schedule.
One of the must-see race cars confirmed for the event is the awe-inspiring 2005 Audi R8 LMP of Travis Engen. A prime example of the Audis that anchored the manufacturer’s dominating LMP1 dynasty, Engen has driven the car to many HSR victories at Sebring.

Another entry is the fast and loud 1970 Ford Mustang Boss 302 entered by Carlus Gann and Vintage Race Car Restorations. The Trans-Am styled Mustang has been driven to several HSR victories in recent years, including a 2019 Sasco Sports overall and American class victory at Barber Motorsports Park in the hands of Motorsports Hall of Famer Bill Elliott.
And Robert Blain, who’s twice earned Run Group or prototype class overall victories in the HSR Classic Daytona presented by IMSA classic 24-hour race, will bring his 1975 March 75S to the Sebring event.
The HSR Spring Fling is the lead-in event for the April 21-25 HSR Mitty at Michelin Raceway Road Atlanta.
