Cayman GT4 Arch Guards – Porsche 981/718 GT4/GTS Mudflaps & Fender Protection Kit
Track-Ready Protection for Your Porsche Cayman
While the Porsche Cayman GT4 and GTS models are born for performance, their wide fenders and sticky tires make them magnets for paint damage. Fortunately, this is where our Cayman GT4 arch guards step in. Engineered to defend your paint from chips, grime, and water spray, these splash guards are the perfect blend of function and form.
Not only do they add a more aggressive stance, but they also extend the lifespan of your lower bodywork — all while blending in seamlessly with OEM aesthetics.
Designed for 981 & 718 GT4 and GTS Models
Because Porsche’s fender shapes vary between generations, this kit is tailored specifically for:
-
Porsche 981 Cayman GT4 / GTS
-
Porsche 718 Cayman GT4 / GTS / T / S
-
Also compatible with base 981 and 718 Cayman models
Although the cars already have aerodynamic styling from the factory, these arch guards provide an added layer of practical protection without disrupting airflow.
What’s Included in the Kit
Each package contains:
-
2x front arch guards (driver + passenger side)
-
2x rear mudflaps / splash deflectors
-
Mounting hardware for direct fit
-
Step-by-step installation guide
These components are precision-molded for tight tolerance, ensuring the flaps sit flush with factory wheel liners and trim.
Built Tough with Performance in Mind
Made from high-grade TPE polymer or textured ABS plastic, these guards offer long-lasting resilience under all driving conditions. Whether you’re carving canyons, hitting track curbs, or battling winter roads, they’ll withstand everything the tires can throw at them.
Thanks to their textured black finish, they resist fading and scuffs while matching OEM bumper plastics.
What is TPE and why it matters for splash guards
Form-Fitting Aesthetics That Elevate Your Cayman
Although they serve a practical function, the Cayman GT4 arch guards also enhance the vehicle’s stance. Their sharp edges and discreet profile help visually widen the body, especially from side and rear angles.
Furthermore, they work flawlessly with both stock and aftermarket aero parts like:
-
Carbon side skirts
-
Rear diffusers
-
Wider wheels and flares
Because of their clean lines, many customers say they look factory-installed — and often go unnoticed unless pointed out.
Protects Where It Matters Most
These guards were engineered to intercept flying debris before it hits vulnerable areas like:
-
Lower doors
-
Rocker panels
-
Rear quarter arches
-
Carbon or painted side skirts
Moreover, by reducing the amount of grime and water sprayed along the body, they also cut down on post-drive cleaning and detailing work.
Whether you’re tracking the car or just navigating rainy roads, these guards are a smart investment that pays off over time.
Easy, Reversible Installation
Fortunately, you don’t need to be a mechanic to install this kit. Because the guards use factory mounting points, installation takes under an hour with basic tools.
Tools Required:
-
Phillips screwdriver
-
Trim removal tool (optional)
-
Cleaning cloth and alcohol wipes
Install Time:
-
~20–30 minutes per axle
-
No cutting, drilling, or glue required
If you ever wish to return the car to stock, the guards can be removed without leaving any marks.
Pairs Well With Other Porsche Upgrades
To complete the ultimate exterior protection and aesthetic package, consider pairing these arch guards with:
With all these installed, your Porsche looks sharper and stays cleaner — even on aggressive drives.
Why These Over Generic Mudflaps?
While other universal flaps claim broad fitment, they rarely complement Porsche styling. These arch guards were CAD-modeled specifically for the GT4/GTS body lines, ensuring:
-
A precise factory-style fit
-
No sagging, flapping, or uneven gaps
-
Seamless integration with fender curvature
-
Durable performance on and off track
As a result, this is the best OEM+ solution for drivers who want to protect their investment without compromising design.
