There's something about a Porsche 911 with aerodiscs on its rear wheels that gets us in the mood to head to the closest racetrack. Soon, the 992.2-generation GT3 will be available with the distinctive add-ons as part of the forthcoming Manthey performance kit, which includes a bunch of other hardcore track-focused hardware.
With the Manthey modifications, the 2026 Porsche 911 GT3 benefits from myriad aero upgrades, significantly increasing the coupe's downforce. The underbody turning vanes are 39 inches longer than the regular GT3, with the Manthey kit's roughly 59-inch section providing more efficient downforce. This also introduces a cover for the trunk floor to complete a seamless surface underneath. Other aero-minded alterations include an extended front lip, canards, and longer rear diffuser fins. Along with larger, curved end plates, the GT3's standard swan-neck rear wing is wider and fitted with a Gurney flap. Overall, Porsche says the Manthey-spec GT3 can generate between 782 and 1190 pounds of downforce.
