What are the differences between the Porsche GT3 and GT3RS?

[VanJasper]

GT3 and GT3RS are high-performance models in Porsche's 911 series, with the GT3RS being a more powerful variant compared to the GT3. The differences mainly lie in three aspects: exterior, interior, and engine. 1. Exterior The GT3RS features more exaggerated aerodynamic components. While the bumper design is largely similar, the GT3RS has a larger front splitter and uses a lightweight carbon-fiber plastic front hood with two NACA cooling ducts. Additionally, the GT3RS has aerodynamic lines on its front hood and roof, which are absent on the GT3. A prominent brake cooling vent, first introduced on the GT2RS, is also present on the GT3RS. The entire exterior design is optimized for aerodynamics and downforce balance. As a track-focused sports car, the GT3RS uses lightweight forged alloy wheels with center-lock nuts. Compared to the GT3, the GT3RS has 20mm wider front and rear tires, with the rear wheel size increased by one inch. The GT3RS is equipped with Michelin Cup 2 tires, sized 265/35ZR20 at the front and 325/30ZR21 at the rear. The front brake discs measure 410mm in diameter, while the rear discs are 390mm, paired with 6-piston front and 4-piston rear calipers in yellow. To ensure sufficient air intake, the engine intake is relocated to the front of the rear fenders, unlike the GT3, which uses a ram-air intake on the engine hood. The GT3RS has a larger and taller rear wing compared to the GT3, featuring an adjustable lightweight mount for customizable downforce on different tracks. The rear bumper vents and diffuser on the GT3RS also differ from the GT3, offering superior aerodynamic performance. 2. Interior The GT3RS interior does not excessively strip out features but implements effective weight-saving measures. It includes lightweight bucket seats, a roll cage, and the removal of metal door handles for further weight reduction. 3. Engine The GT3RS shares the same 4.0-liter flat-six naturally aspirated engine as the GT3 but produces 21 more horsepower and 10Nm more torque, totaling 470Nm. These are the key differences between the Porsche GT3 and GT3RS. The 911 lineup includes various models such as the Carrera, Carrera S, GT3, GT3RS, GT2RS, etc. All Porsche 911 models feature rear-mounted engines with horizontally opposed configurations.
