APR Performance Rear Diffuser - AB-545050

If you're looking to enhance the aerodynamics of your Porsche 981 Cayman or Porsche 981 Cayman GT4 (2015-2016), the APR Performance Rear Diffuser (AB-545050) is a game-changer. This high-quality component is designed to seamlessly integrate with your factory rear bumper, effectively reducing lift and drag while improving overall stability at high speeds.

Why Choose the APR Performance Rear Diffuser?

The AB-545050 is constructed using pre-preg carbon fiber materials, ensuring a lightweight yet robust design. Formed in an autoclave at high temperatures, this diffuser not only offers significant weight savings but also exceptional durability. It’s molded to fit perfectly with your vehicle's underbody, making installation straightforward and hassle-free.

How It Works

As your Porsche moves forward, it displaces air, creating a low-pressure vacuum at the rear. The APR Performance Rear Diffuser channels high-speed airflow from underneath the car, helping it transition smoothly into this vacuum. This process enhances downforce and allows other aerodynamic components, like wings, to perform more effectively. You'll notice improved handling, especially during spirited driving or on the track.

Key Features

  • Pattern: 2x2 twill weave for a sleek finish
  • Material: Made from 3K pre-preg carbon fiber for strength and lightweight performance
  • Coating: UV-stable clear coat to protect against the elements
  • Mounting: Comes with pre-drilled holes for easy installation
  • Hardware: Includes stainless-steel machine screws, washers, and nuts for secure mounting

Fitment

APR Racing Applications

Here is a brief overview of some of the most popular APR racing components.

Front Air Dams

APR Performance has created a top-of-the-line front air dam. Front air dams are added to the front bumper to increase your car’s stability when driving at high speeds, as well as reduce front end lift.

APR Wing

An APR wing increases high-speed stability while simultaneously providing rear-end downforce.

APR Performance offers two different kinds of wings, allowing customers to choose between GT Series Adjustable Wings or GTC Series Adjustable Wings. The primary difference between the two is that the GT Series comes in three configurations: single element, dual element or swan neck configurations.

APR Splitter Rods

APR splitter rods reinforce the Front Wind Splitter, which reduces front-end lift and optimizes high-speed stability.

Rear Deck Spoilers

APR Performance rear deck spoilers fine-tune any downforce balance. As the name suggests, rear deck spoilers are integrated into the rear deck of your car.
