Porsche Cayman GT4 (981) - ALU wheels – Sold as pair

Set of lightweight carbon fiber rear wheel covers for improved downforce.

Fits:

• Porsche Cayman GT4 3.8L 2015-16

Aero discs play a crucial role in streamlining the airflow around the rear wheels, preventing turbulence that can adversely affect the efficiency of the rear wing.

Carbon fiber Aero discs are made with pre-preg carbon fiber, cured in autoclave. The set is fully reversible and requires no cutting or modifying of any original parts. It supports an OEM+ look, with stunning carbon fiber appearance in a variety of finishes, all providing great UV protection.

It is compatible with stock 981 GT4 - ALU wheels.

Choose between a matte and gloss carbon fiber finish. Decals are offered in 4 basic colors: Black, Red, Yellow and White, or you can opt for a completely bespoke color. Please write the desired color in the Cart comment section.

The design can also be changed to any other design or deleted.

Installation Process

The installation process of the Aero discs is straightforward and can be done by any car enthusiast. It comes with detailed instructions to ensure a smooth and hassle-free installation.

Each Aero Disc assembly consists of several components: the visible carbon fiber disc on the wheel face and the hidden mounting mechanism located within the central wheel opening.

To install the Aero Disc assembly:
1. Insert the base from the back of the wheel into the central wheel opening.
2. Fit the centering ring from the front of the wheel into the wheel cap recess.
3. Secure the base and hub together using the provided nut and washer.
4. Install the custom wheel cap to complete the assembly.

What Rear Wheel Aero Discs Do

Rear wheel aero discs are used in motorsport and high-performance applications to reduce turbulence generated by open wheel spokes.

Core Functional Benefits

• Reduce aerodynamic drag around the rear wheels
  
• Improve high-speed stability by smoothing airflow
  
• Increase aerodynamic efficiency, especially on fast straights
  
• Support better flow toward the diffuser and rear wing
• Provide a sleek, flush carbon fibre appearance
• Enhance the GT4’s already effective downforce platform

On a mid-engine Porsche like the 981 Cayman GT4—where aerodynamic precision is crucial—rear aero discs help stabilise the car at speed and improve overall aero balance.
