Product Description

This Akrapovic Rear Carbon Fiber Diffuser adds aggressive, race‑inspired aerodynamics to the Porsche 718 Cayman GT4 RS / Spyder RS, enhancing both rear‑end styling and performance. Handcrafted from high‑quality, race‑proven carbon fiber and finished in matte weave, it complements the lines of the GT4 RS and coordinates perfectly with Akrapovic exhaust systems. Lightweight yet incredibly stiff, this diffuser sharpens rear airflow, adds visual presence, and reduces overall mass over the stock component, making it a compelling upgrade for both track enthusiasts and street‑driven performance cars.

Fitment Notes

  • Designed for Porsche 718 Cayman GT4 RS (982) & 718 Spyder RS — model years 2022 – present. 

  • Works seamlessly with Akrapovic Slip‑On and Evolution exhaust systems — matches the OEM exhaust aesthetics and mounting points. 

  • Track and high‑speed driving applications highly benefit from the lighter, stiffer design.

Included

  • Matte‑finish carbon fiber rear diffuser panel tailored to the 718 Cayman GT4 RS / Spyder RS.

  • Replaceable rubber protectors on lower edges to guard against track‑surface abrasion. 

  • All necessary mounting hardware for direct installation on compatible vehicles.

Product Specs

  • Material: Hand‑laid, race‑proven carbon fiber — optimal strength‑to‑weight ratio. 

  • Finish: Matte carbon fiber weave for a stealth performance look. 

  • Weight Savings: Approx. 2.4 kg reduction vs. stock diffuser panel.

  • Design Intent: Aerodynamically optimized to smooth rear airflow and lend a more aggressive rear appearance. 

  • Complementary Products: Designed to visually pair with Akrapovic exhaust systems for a cohesive upgrade package.

Product Features

  • Race‑Derived Construction: Built from lightweight carbon fiber with racing pedigree, reducing mass behind the rear axle for improved dynamics.

  • Enhanced Aerodynamics: The diffuser’s sculpted profile helps manage airflow under the rear of the vehicle, enhancing stability at speed — ideal for aggressive road driving or track use.

  • Matte Finish Look: A purposeful, non‑gloss finish that visually cues performance intent and pairs well with carbon‑trim or matte exterior accents. 

  • Durable, Track‑Ready Design: Integrated rubber protectors on the lower leading edges help prevent abrasion from track curbs or uneven surfaces.
