GT4 America - Round 4 & 5

The Pirelli GT4 America Series brings Rounds 4 & 5 to Sebring International Raceway in Sebring, Florida. This event features two 60-minute sprint races that showcase GT4-homologated cars across three competitive classes. Approximately 30 entries compete in the Silver, Pro-Am, and Am divisions, with classifications based on FIA driver rankings.

Race Format and Competition

The weekend schedule includes two test sessions followed by practice sessions, qualifying, and two sprint races. Each 60-minute race tests driver skill and team strategy at one of America's most challenging circuits. Teams from organizations including Skip Barber Racing, ProSport Competition, JMF Motorsports, Archangel Motorsports, Heart of Racing Team, FASTMD Racing with Remstar, and Random Vandals Racing bring their GT4 machinery to compete.

Both races stream live on SRO's GT World YouTube channel and Twitch, providing fans worldwide access to the action. The competition features manufacturers such as BMW, Porsche, Toyota, and Aston Martin, with teams pushing their GT4 cars to the limit.

Sebring International Raceway

Sebring International Raceway measures 3.74 miles with 17 turns that combine long straights, high-speed corners, and technical slow-speed sections. The circuit surface mixes asphalt and concrete, including original concrete from 1941 when the site served as Hendricks Army Airfield, a B-17 training base during World War II.

Circuit Characteristics

The track demands balanced car setups. Turn 17 stands out as a high-speed, bumpy right-hander that significantly affects lap times. This corner is wide enough for three cars and directly impacts speed down the front straight. The bumpy surface throughout the circuit creates unique mechanical challenges for teams and tests driver adaptation.

The demanding nature of Sebring pushes both machines and drivers. Teams must optimize their GT4 cars for the mixed surface conditions while maintaining reliability. Driver changes during pit stops add another strategic element to the 60-minute races.

Historic Racing Venue

Sebring International Raceway holds the distinction as America's oldest road racing circuit. The first race occurred on New Year's Eve 1950. The venue hosted the inaugural 12 Hours of Sebring in 1952, and in 1959, it welcomed the first Formula One race held in the United States.

The facility operates more than 300 days per year with private testing, club events, corporate activities, and driving schools. This active schedule maintains Sebring's position as a cornerstone of American motorsports.

Fan Experience

Sebring offers open access to paddocks and garages, allowing fans close proximity to the teams and cars. Autograph sessions and fan zones provide opportunities for interaction with drivers and crew members. The atmosphere combines professional racing with accessible fan engagement.

Technical Challenge

GT4 America competitors face unique demands at Sebring. The bumpy surface requires suspension setups that balance compliance with performance. High-speed sections test aerodynamic efficiency while technical portions demand mechanical grip. Teams work to minimize pit stop times while ensuring smooth driver changes.

The GT4-homologated cars represent various manufacturers, each with distinct characteristics. Teams must extract maximum performance from their platforms while managing tire wear and fuel consumption across the 60-minute race distance.

What Makes This Event Special

Rounds 4 & 5 at Sebring International Raceway combine historic significance with modern GT4 competition. The challenging circuit reveals driver talent and team preparation. Weather conditions can add unpredictability, with temperatures, humidity, and potential storms influencing race strategy.

The sprint race format delivers close competition from green flag to checkered flag. Multiple classes racing simultaneously creates varied battles throughout the field. Each race offers points crucial for championship standings, raising the stakes for every lap.

This gt4-america event at Sebring represents a significant test for all competitors. The combination of circuit history, technical demands, and competitive depth makes these races essential viewing for sports car racing fans. The return to traditional sprint racing format emphasizes pure speed and strategy at one of motorsports' most respected venues.
