  1. Aerodynamics: The kit includes a range of carbon fiber aerodynamic components, including a front splitter, rear wing, and side skirts. These components are designed to reduce drag and improve downforce, which enhances the stability and handling of the vehicle at high speeds.
  2. Suspension: The Manthey Performance Kit also includes a set of bespoke KW Variant 3 coilovers, which are adjustable and offer improved handling and ride comfort. The suspension is also lowered by 30mm, which helps to improve the car’s center of gravity and reduce body roll.
  3. Brakes: It comes with upgraded brake pads and steel-braided brake lines, which help to improve the braking performance of the vehicle. The brakes are also cooled by an additional air duct, which helps to prevent brake fade during hard driving.
  4. Wheels and Tires: The 911 GT3 kit comes with a set of lightweight forged wheels, which reduce unsprung weight and improve the car’s handling. The wheels are wrapped in high-performance Michelin Pilot Sport Cup 2 tires, which offer exceptional grip and handling in both wet and dry conditions.
  5. Engine: It includes an ECU tune and a sports exhaust system, which increases the power output of the 4.0-liter naturally aspirated flat-six engine. The engine now produces 520 horsepower and 346 lb-ft of torque, which is a noticeable improvement over the stock engine.

Let’s take an even closer look at the Manthey Performance Kit for the Porsche 911 GT3:

According to Porsche, the modifications are focused on aerodynamics and chassis components. 

The new Performance Kit was developed in close collaboration between the Porsche engineers in Weissach and the Nordschleife specialists from Manthey in Meuspath. The Porsche Tequipment circuit-optimized components are sold through Porsche Centers.

The extensive changes to the aero package are what make the Manthey Kit for the 911 GT3 recognizable.

A larger spoiler lip and side flaps are fitted at the front of the car. In conjunction with the modified air guide elements on the underbody, they increase the downforce on the front axle.

The modifications at the rear are even more pronounced.

The swan-neck-supported wing of the 911 GT3 is wider, and now features a tear-off edge (Gurney). The end plates with their distinctive Manthey logos have also been enlarged, as has the wing’s angle of attack. The fins of the rear diffuser have been extended and are now made of CFRP. The aerodiscs on the rear wheels, which are also made of CFRP, further enhance the car’s aerodynamic efficiency.

The ultimate driving experience: Porsche Ice Experience

In collaboration with Manthey, Porsche has developed a special four-way coilover suspension for the 911 GT3 that can be adapted for use on the circuit.

The suspension struts can be adjusted to four positions, and rebound and compression can be tweaked without tools. The moderate changes to the spring rates (10 percent higher on the front axle, seven percent lower on the rear) contribute to improved on-the-limit handling, without making any compromises necessary when it comes to day-to-day usability.

A lightweight forged wheelset with 20- and 21-inch rims is available as an option for the Porsche 911 GT3. They reduce unsprung mass by a total of 7.3 kilograms. They are available in Brilliant Silver, Dark Silver, Neodyme, and (satin-gloss) Black. A set of brake lines with steel braids come as standard with the kit.

They guarantee a very precise pressure point and thereby ensure optimal modulation of the brakes. Special racing brake pads are available as an option for the 911 GT3 with the Manthey Performance Kit. Door projectors and illuminated door sill guards with the Manthey logo help to personalize the car visually. A towing loop is also included in the kit.

The 911 GT3 with the Manthey Kit was able to unleash its full potential on the Nürburgring Nordschleife, the traditional test laboratory for sports cars at Porsche.

With Porsche Works driver Kévin Estre at the wheel, the modified GT sports car ripped around the 20.8-kilometer course in Germany’s Eifel region in 6:55.737 – 4.19 seconds faster than the standard 911 GT3 did a year earlier. Both vehicles were equipped with the optional Michelin Pilot Sport Cup 2 R tires. The lap time was certified by a notary who was present on site.
