Few cars transfer motorsport technology to the road like the 911 GT3 RS. The Manthey Kit takes that capability even further, sharpening aerodynamic efficiency, suspension set-up and braking performance for drivers who want to extract the very maximum on track.
Developed in close collaboration between the Porsche Development Centre in Weissach and Manthey in Meuspath, the package significantly increases downforce, delivering higher cornering speeds and greater stability under extreme conditions.
Aerodynamic revisions include a larger front spoiler lip, dive planes, a lightweight carbon-fibre rear window with a motorsport-inspired shark fin, roof fins for improved airflow, and a revised rear wing and diffuser. Together, these upgrades generate over 1,000 kg of downforce at 177 mph — all without increasing drag.
The semi-active coilover suspension is recalibrated to match the added load, while steel-sheathed brake lines provide sharper pedal feel and faster response. For vehicles equipped with Porsche Ceramic Composite Brakes, optional track-focused pads further reduce fade and enhance control.
A range of visual upgrades, from illuminated carbon door sills and decals to coloured towing eyes, allows owners to underline the unmistakable Manthey character.
