Porsche 981 Cayman GT4
The Dive Planes for the Porsche 981 Cayman GT4 are specifically designed to increase front-end downforce, increase the high-pressure airflow to the factory intake duct, and to keep drag increase minimal.
These units are constructed from 1.5mm thick pre-preg, autoclaved cured, 2x2 twill carbon, with a matte clear finish.
Dive planes also referred to as canards, allow you to shift the aero balance forward, possibly aiding you and your setup in balancing out a large rear wing or diffuser.
Kit Includes
• Dive Plane x 4 (Upper x 2, Lower x 2)
• 3M VHB Tape (4 Pieces, 1 for each Dive Plane)
• Install Template
• Hardware Kit, Includes All Hardware for Install

Front splitters are very effective at producing front end downforce without increasing drag significantly. They do this by creating a large pressure delta between the top and bottom surfaces. We then incrementally improved the front splitter by adding design tweaks to the underside of the splitter to improve flow with our carbon splitter diffusers.
The splitter is produced from a carbon thermoplastic, which is the same material used in high forms of Motorsports. The material is not brittle, so no more issues with cracking like carbon fiber and ABS. It will not grab and bend under the car like aluminum units either. It is a great splitter material.
The air dam is used to bring the splitter flat with the vehicle's underbody and improve performance further. The air dam is produced with pre-preg carbon fiber and is cured in an autoclave for reduced weight and improved strength.

• Carbon Spill Plate (2)
• Carbon Front Air Dam

Porsche Front Spoilers & Bumpers | Aerodynamic Styling & Performance Enhancement
Front spoilers and bumpers play a crucial role in your Porsche’s aerodynamics, cooling, and visual design. They’re not just about appearance — they help reduce front-end lift, channel airflow to radiators and brakes, and improve stability at high speeds. Whether you’re restoring, replacing, or upgrading, a precision-designed front spoiler ensures both form and function work in perfect balance.
At Design911, we offer a wide range of high-quality front spoilers and bumpers crafted for exact fitment and superior finish. Designed to match manufacturer-level standards, our selection includes parts for classic air-cooled 911s through to modern 992, Taycan, and Cayman models. Each spoiler is engineered to enhance aerodynamic efficiency, cooling performance, and the distinctive styling that defines every Porsche.
Whether you’re replicating a classic GT look, improving track performance, or refreshing worn components, Design911 supplies front spoilers and bumpers that elevate your Porsche’s performance and aesthetics.
What Do Front Spoilers and Bumpers Do?
Front spoilers (also called splitters) and bumpers are more than exterior styling elements — they are key aerodynamic devices designed to manage airflow and stability.
Core Functions:
- Reduces
aerodynamic lift to improve high-speed handling.
- Directs
airflow to radiators, brakes, and intercoolers.
- Improves
cooling efficiency under performance driving conditions.
- Protects
key front-end components from debris and road damage.
- Enhances vehicle appearance with a sportier, more aggressive stance.
For performance-oriented Porsche owners, upgrading to a well-designed spoiler or bumper can significantly enhance aerodynamic balance, making the car more composed and predictable on both road and track.
Why Do Front Spoilers and Bumpers Fail or Degrade?
Front spoilers are constantly exposed to road debris, impacts, and environmental wear. Over time, they can lose integrity, affecting both aesthetics and aerodynamic performance.
Common Causes of Failure Include:
- Impact
damage from curbs, stones, or speed bumps.
- Cracking
or chipping due to low ground clearance.
- UV
and weather damage causing discoloration or fading.
- Corrosion
or fatigue of mounting brackets or hardware.
- Misalignment or distortion from poor installation or age.
A damaged or poorly fitted front spoiler not only affects vehicle handling but can also compromise airflow to vital cooling systems, making timely replacement essential.
Why Replace or Upgrade Your Porsche Front Spoiler or Bumper?
Replacing or upgrading your Porsche’s front spoiler ensures optimal aerodynamics, cooling efficiency, and design integrity — while restoring or improving the car’s distinctive road presence.
Key Benefits:
- Restores
aerodynamic stability and downforce balance.
- Improves engine and brake cooling efficiency.
- Enhances
front-end protection against debris and damage.
- Precision
fitment for seamless integration and clean lines.
- Lightweight
construction for improved performance.
- Available in fiberglass, polyurethane, and carbon fiber.
Upgrading your spoiler or bumper also allows for personalisation — whether you prefer a classic look inspired by 911 RSRs or a modern GT aesthetic.
Highlights:
- Premium-quality Porsche front spoilers and bumpers.
- Designed for aerodynamic efficiency and visual appeal.
- Lightweight yet durable materials for long life.
- Direct-fit design ensures easy installation.
- Available for 911, Cayman, Boxster, Panamera, Taycan and more.
