Race Series

HSR provides an exciting venue for year-long sprint and endurance series events.  See below for a complete description of each of inter-series.

SPRINT SERIES

If it’s been raced on a road course, there’s a pretty good change you’ll see it in the WeatherTech Sprint Series!  These events are all-out sprint races, and are usually eight to twelve laps, depending on race venue and time allotment.

The WeatherTech Sprint Series features ten different groups of cars, grouped together by classes due to similar vintage and engine displacement to provide extremely close competition.  The groups vary from open-wheel formula cars, early 60’s vintage GT racers & more modern GT cars.

Providing spectacular wheel-to-wheel action, the WeatherTech Sprint Series is a crowd favorite.

ENDURANCE CHALLENGE

A key component to the heritage of sports car racing is the endurance event.  Great motorsports events such as the 24 Hours of Le Mans have been in existence almost as long as the automobile, and many of the race cars entered in HSR competition were originally campaigned in endurance racing.  To keep the spirit of endurance racing alive for these cars, their drivers and mechanics, HSR has created the Endurance Challenge, sponsored by B.R.M Chronographes.

Representing the only true historic endurance series in the United States, the B.R.M. Chronographes Endurance Challenge consists of five separate groups, Vintage, GT Classic, GT Modern, Historic and Prototype.  Cars are classed based on the model year and type of the race car.  The Endurance Challenge is a one hour endurance race, with a 5 minute required pit stop.

INTERNATIONAL/AMERICAN CHALLENGE

The Bob Woodman Tires International/American Challenge is open to all Foreign Production Sports Cars & Sedans (over 1.5L) and American GT Cars by invitation (Groups 2, 3, 5).  The BWIAC is a sprint race series featured at every HSR event weekend.  The BWIAC is a competitor and crowd favorite, as fans are dazzled by the on track action during each one of these races.  The overall winner receives a uniquelly designed trophy.

INTER-SERIES CHALLENGE

A throw back to the International Race of Champions (IROC).  Welcome to all competitors with existing race-prepared Porsche RS 2.7L through 3.0L race cars.  All championship eligible cars must compete with an approved safety system and stock make and model engine and transmission, with approved allowances for exhaust and intake modifications. The Inter-Series features sprint races at select race venues throughout the season.  The Champion of the Classic RS Cup is awarded a special edition B.R.M Chronographe.  Please see the Classic RS Cup Series Page for more information on Rules and Inter-Series Point Standings.
