GT3 is a global sports car racing category where manufacturers like Porsche, Ferrari, Mercedes, BMW, and Aston Martin build race-ready versions of their road cars. All cars are “BoP’d” (Balance of Performance), meaning officials adjust things like weight and power so no brand has an unfair advantage. Races can be sprint or endurance, and cars are driven by a mix of pro and amateur drivers.

GT4 race cars are pure-bred racing machines that balance raw power with precision engineering, built to thrill both drivers and spectators alike. Unlike the ultra-modified GT3 cars, GT4 vehicles are much closer to their street-legal counterparts, but don’t let that fool you—they are fierce, agile beasts designed to dominate the track. Each car is stripped of unnecessary luxuries and equipped with racing-grade components: roll cages, adjustable suspensions, and aerodynamic enhancements, all to optimize speed and control.

The Porsche 992 Cup car is a brutal, no-nonsense racing machine that demands absolute precision from those who dare to push it to its limits. Driving the 992 Cup car is like walking a tightrope, especially when it comes to braking. With no ABS to cushion your mistakes, the car forces you to be perfect. Even a slight miscalculation of brake pressure can lock up the wheels, sending the car skidding into corners with a screeching protest of tortured rubber. The massive brakes provide incredible stopping power, but you have to modulate them with surgical precision to avoid locking up and ruining your lap. It’s a dance of controlled aggression, balancing on the edge of disaster as you manage weight transfer and find the razor-thin margin between speed and grip. It’s the unforgiving nature of its handling that separates the best drivers from the rest.

IMSA is a major North American sports car racing championship. It features different classes racing on track at the same time, including top-level prototypes and GT cars. Events range from short sprint races to famous endurance races like the 24 Hours of Daytona and 12 Hours of Sebring. It’s known for close racing, multi-class strategy, and a festival-style atmosphere at events.

GTP is the top class in IMSA, featuring high-tech hybrid prototype race cars from manufacturers like Porsche, BMW, Acura, Cadillac, and Lamborghini. These aren’t based on any road car — they’re purpose-built for speed and endurance. They use hybrid power for extra boost and efficiency, and they race at major endurance events competing for overall wins.

The GR86 Cup is a one-make series where all drivers race identical Toyota GR86 cars. Because the cars are the same, races are extremely close and focus on driver skill rather than budget or engineering. It’s popular for young drivers learning race craft and for club racers wanting affordable but competitive racing.
