The Manthey Performance Kit unlocks the full potential of the Porsche 911 GT3 for the racetrack. Developed through a collaboration between Porsche and racing experts Manthey, it delivers sharper handling, faster cornering, and an unforgettable adrenaline rush. The Manthey Performance Kit isn’t just for professional drivers. Thanks to the kit’s enhanced handling and performance capabilities, it even helped Porsche factory driver Kévin Estre achieve a blistering lap time of 6:55.737 minutes on the Nürburgring Nordschleife. This transformation is achieved through the addition of 14 high-performance race parts that enhance suspension, aerodynamics, brakes, and other accessories. Years of racing experience, countless simulations, and extensive testing on the Nürburgring ensure each component is optimized for peak performance.

A Breakdown Of The 911 GT3 Manthey Performance Kit

Manthey Racing offers performance kits for several models:

• GT4

• GT4 RS

• 911 GT2

• 911 GT3

• 911 GT3 Touring

• 911 GT3 RS

In this post, we’ll go over the performance upgrades you get with the kit for the standard GT3. A sculpted front spoiler strategically placed flaps, and underbody enhancements that boost downforce on the front axle by 30%. A redesigned rear diffuser with extended fins and a larger carbon fiber wing (featuring a distinctive Manthey logo) increases downforce at the rear by 45%.

A meticulously tuned suspension system with fully adjustable 4-way dampers allows for fine-tuning based on track conditions and driver preferences. Slightly stiffer springs (+10% front, -7% rear) optimize handling and balance. Lightweight components contribute to a more responsive driving experience.

The optional Manthey lightweight wheels shave off 16.1 pounds (7.3 kg) per set, noticeably improving suspension response and overall control. These wheels come in a variety of stylish finishes to complement your GT3. Porsche recommends pairing the Manthey Performance Kit with Michelin Sport Cup 2 R tires for optimal performance.

Carbon Aerodiscs on the rear wheels smoothen airflow, further improving aerodynamic efficiency. Upgraded steel-sheathed brake lines provide a more direct pedal feel and quicker response times (developed and tested by Manthey on the legendary Nürburgring Nordschleife). Optional racing brake pads deliver consistent performance across temperature ranges, minimizing wear, and reducing rotor damage.

Two red towing loops are included for racetrack use (must be removed for public roads). Illuminated door entry guards boast a sleek carbon fiber finish with the Manthey logo. LED door projectors cast a Manthey logo onto the ground when exiting the vehicle. The kit is compatible with both the standard 911 GT3 wheels and the optional lightweight Manthey wheels.

The Manthey Performance Kit transforms the 911 GT3 into a true track weapon. While the $60,500 may seem steep, shaving off precious seconds at the track should help justify the steep asking price. With its factory-approved meticulously crafted aerodynamic upgrades, precision handling, race-ready components, and lightweight options, this kit empowers drivers to exploit and experience the full potential of their 911 GT3 and push their limits on the racetrack.
