Air pressure difference can cause the rear screen to pop out of its seal / opening, especially if spinning or heading backwards.
These restraints are the solution to this problem. Laser cut from aluminium and CNC bent with a durable black anodised finish.

Please Note
For glass applications we recommend applying a thin layer of foam between the restraint and the glass.

About Roof Spoilers & Skins

Roof Skins & Roof Spoilers - Exterior Styling & Aerodynamic Upgrades

Roof skins and roof spoilers play a crucial role in a vehicle’s exterior styling, aerodynamics, and high-speed stability. Designed to enhance airflow over the roofline, these components reduce lift, improve downforce balance, and give your Porsche a more aggressive, motorsport-inspired appearance.

At Design911, our Roof Skins & Roof Spoilers category offers precision-engineered upgrades designed to replace or enhance factory components, delivering improved performance, durability, and visual impact for road and track-focused vehicles.

What Do Roof Skins & Roof Spoilers Do?

Roof skins and roof spoilers optimise airflow across the roof and rear of the vehicle.

Core Functions:

  • Improve aerodynamic efficiency and airflow management
  • Reduce rear-end lift at higher speeds
  • Enhance vehicle stability and handling
  • Update exterior styling with a sportier profile
  • Support balanced downforce when combined with rear spoilers or wings

These components are especially valuable for performance-oriented Porsche models driven enthusiastically or on track.

Why Do Roof Skins & Roof Spoilers Fail?

Factory roof skins and roof spoilers can degrade or underperform over time due to:

  • UV exposure causing fading or material breakdown
  • Age-related cracking or warping
  • Adhesive or mounting point failure Insufficient aerodynamic performance at higher speeds
  • Outdated styling compared to modern Porsche designs

Plastic and composite factory components are particularly prone to wear, making upgrades both a functional and aesthetic improvement.

Why Upgrade Your Roof Skin or Roof Spoiler?

Upgrading delivers measurable benefits in both performance and longevity.

Upgrade Advantages:

  • Enhanced aerodynamic efficiency and reduced lift
  • Improved high-speed stability and driver confidence
  • Stronger materials such as carbon fibre or reinforced composites
  • Motorsport-inspired styling upgrades
  • Improved resistance to heat, UV, and environmental wear

Performance roof skins and roof spoilers from Design911 are engineered for precise fitment and long-term durability.

Highlights

  • Porsche-specific roof skins and roof spoilers
  • Designed for aerodynamic efficiency and styling enhancement
  • High-quality materials including carbon fibre options
  • Ideal for road, fast-road, and track-focused builds
  • OEM-fitment or performance-upgrade solutions
