In Historic Sportscar Racing (HSR), the cars are the stars and the spectators are treated to prior winners of great events such as the 12 Hours of Sebring, 24 Hours of LeMans and 24 Hours of Daytona. Events are as educational as they are adrenaline-inducing as fans are exposed to pieces of history at the track. HSR events represent fast-paced, wheel-to-wheel racing. To keep competition close, cars are generally grouped according to age and engine size for racing. HSR features several separate series, which range from the heart-pumping GTP/Group C Series featuring GTP prototypes to the Hawk Performance Endurance Series presented by B.R.M., which includes historic production and prototype sports cars. Perhaps the best part of HSR events is the open feeling experienced by spectators; unlike other series, fans can stroll through the paddock to view the cars and talk with the drivers. Often, racing legends are on hand driving cars they previously raced.
