Best Carbon Fiber Upgrades for Porsche 718 Boxster & Cayman: Fenders, Wings & Aero

The Porsche 718 Boxster and Cayman are precision sports cars with a devoted enthusiast following — and carbon fiber upgrades are a natural extension of their performance character. Our 718 products are consistently among the most viewed on the site. Here’s what 718 owners are buying.

Most Viewed: RS-Style Carbon Fiber Fenders

The RS-style carbon fiber front fender set for the Porsche 718 Boxster and Cayman is one of the most viewed products on our site for this platform. Inspired by the GT4 RS wide-body design, these fenders add width and visual aggression to the 718’s front end — transforming the standard 718 into a GT4 RS-inspired build without the GT4 RS price tag.

Best for: Porsche 718 Boxster, 718 Cayman, 718 GTS (981 and 982 chassis)

1. RS-Style Carbon Fiber Front Fenders

The RS-style fenders are the defining upgrade for the 718 platform. They replace the OEM front fenders with wider carbon fiber units that add visual width and a more aggressive stance. The design references the 718 GT4 RS wide-body — one of the most visually dramatic Porsches ever produced. Available for both 981 (2012–2016) and 982 (2016+) chassis.

2. GT4-Style Carbon Fiber Rear Spoiler / Wing

The GT4-style carbon fiber rear spoiler is one of the most popular upgrades for the 718 Cayman. It adds a high-mounted wing that references the GT4’s factory aero package — adding real downforce and visual drama to the Cayman’s rear end. Available for 981 and 982 chassis in gloss and matte finish.

Best for: Porsche 718 Cayman, Cayman S, Cayman GTS (981/982)

3. Carbon Fiber Front Splitter

A carbon fiber front splitter adds front-end downforce and sharpens the 718’s front fascia. Works particularly well in combination with the RS-style fenders for a complete front-end transformation. Available for standard and GTS bumpers.

4. Carbon Fiber Rear Diffuser

A carbon fiber rear diffuser adds aerodynamic function and visual depth to the 718’s rear bumper. The Cayman’s rear end responds particularly well to a diffuser — the mid-engine layout means the rear bumper has a clean, uncluttered design that a diffuser enhances without looking out of place.

5. Carbon Fiber Mirror Caps

Mirror caps are a popular entry-level upgrade for 718 owners. The Porsche’s prominent door mirrors make carbon fiber caps one of the most visible detail upgrades on the car. Easy to install and immediately impactful.

981 vs 982 Fitment

Most carbon fiber exterior parts are chassis-specific between 981 and 982. Always confirm your chassis before ordering. The GT4 and GT4 RS have different bumper profiles than the standard 718 — confirm trim level as well.
