The Porsche 911 GT3 RS (992 chassis) represents the absolute pinnacle of street-legal, track-focused performance. Powered by a motorsport-derived 4.0-litre naturally aspirated flat-six engine producing 525 PS and 465 Nm of torque, it screams to an incredible 9,000 rpm redline. Paired exclusively with a close-ratio 7-speed PDK transmission, and featuring a revolutionary central radiator concept alongside active DRS aerodynamics, this platform generates up to 860 kg of downforce.

JXL Performance supplies the elite aftermarket components required to maintain, tune, and optimise your 992 GT3 RS. Explore our full selection of upgrades by category:

To improve engine breathing and exhaust velocity, browse our Intake and Exhaust sections, and manage track temperatures with our Cooling upgrades. Fine-tune your chassis alignment with our Suspension options, optimise fitment using Wheels/Spacers, and maintain consistent deceleration with our Brakes components. For dedicated motorsport builds, explore our Engine Build and Drivetrain hardware, tailor your cabin with Interior seating, and adjust aerodynamic balance via our Exterior range. Keep your 9,000 rpm flat-six operating reliably using genuine-spec Service Parts. You can also browse our complete inventory in the Shop All Parts collection.
