Manthey has introduced a performance kit designed specifically for the Porsche 911 GT3 RS. The modifications aim to improve track handling through aerodynamic adjustments and mechanical refinements developed over a two-year period.
Why it matters
The kit is intended to push the boundaries of the vehicle's track capabilities by increasing downforce and refining suspension response. These improvements reflect a specialized effort to optimize the car for high-performance driving environments like the Nürburgring.
The kit generates over 1,000kg of downforce at 284km/h and increases front axle spring rates by 30% alongside a 15% increase for the rear. Additionally, the carbon fibre rear window panel offers a 25% weight reduction.
