Manthey is celebrating its 30th anniversary with two exclusive Porsche race cars, and just 15 examples of each will be built. The Porsche 911 GT3 Cup MR 30 and 718 Cayman GT4 RS Clubsport MR 30 made their debut at the DTM season finale at Hockenheim, combining three decades of motorsport experience with extensive performance upgrades.
The biggest mechanical change comes with the 911 GT3 Cup MR 30, whose water cooled flat six has grown from its original displacement to 4.2 litres, producing 560 PS. Power goes to the rear wheels through a sequential six speed gearbox, while revised aerodynamics, improved cooling, wider tracks and six way adjustable suspension further sharpen its track performance.
Recycled carbon fibre body panels and bespoke forged wheels also help reduce weight, with the wheels alone saving 3.8 kg.
The 718 Cayman GT4 RS Clubsport MR 30 retains its naturally aspirated 4.0 litre flat six, producing 500 PS. It receives extensive carbon fibre bodywork, revised aerodynamics, improved brake cooling and lightweight wheels that contribute to a 5.7 kg weight saving.
The Cayman is particularly significant because it represents the final evolution of Manthey’s decade long development programme for the mid engined platform in GT4 racing.
Both cars feature exclusive white and red anniversary liveries, commemorative badges and embroidered seat details. They are built for circuit use rather than public roads.
Order requests close on 30 October 2026. Cayman deliveries begin in November, while the 911 is scheduled to arrive in the first quarter of 2027. Prices have not been publicly disclosed.
With just 30 cars available worldwide, these anniversary models celebrate Manthey’s racing heritage while giving collectors and competitors a final opportunity to own the most developed versions of these two race car platforms.
