The lighter weight, fabulous gearbox, sweet motor, improved downforce, new-for-2021 antilock brakes and bespoke 18-inch Michelin race tires stand out as the most noticeable changes on the new GT3 Cup.

As you enter the GT3 Cup, you're met with a stripped interior, multifunction yoke-style steering wheel, a 10.3-inch color monitor, a six-point harness system and full roll cage.
