About Fibre Glass

Fibre Glass for Porsche

Fibre Glass parts for Porsche models from Design911, typically used for lightweight panels, body repairs, and styling upgrades where outright originality is less critical than function and cost-effectiveness.

A Quick Look at Fibre Glass

Fibre Glass parts are typically chosen for lightweight panels or cost-effective body repairs, often on track builds or classic restorations. Real-world reasons include replacing corroded metal panels, reducing weight, or repairing damage where originality isn’t the priority.

Choosing the Right Fit for Your Porsche

Where Fibre Glass is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons to choose Fibre Glass parts include replacing rusted steel panels, repairing damage after impacts, or reducing weight on track-focused or modified Porsche builds.
  • Common issues with Fibre Glass parts include cracking, star-crazing in paint, inconsistent panel gaps, edge chipping, and mounting points needing reinforcement, especially if preparation or fixings are poor.
  • Watch for real-world symptoms such as rattles, panels that move at speed, or paint micro-cracks around fasteners, and address mounting strength and alignment before final paint.
  • Test-fit Fibre Glass parts on the car before painting, reinforce critical mounting points where needed, and use a bodyshop familiar with composite panels to achieve the best finish.
  • Expect some adjustment compared with OEM metal or plastic panels; allow time for trimming, shimming, and trial fitting to achieve acceptable gaps and shut lines.
  • Always confirm you are happy with the fit and look of the part before committing to colour-matched paint, as painted parts are usually not returnable.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Exterior Styling / Spoilers — Owners change exterior styling parts to update the look, improve aerodynamics, replace damaged trim, or match a specific Porsche style (OEM, GT, or motorsport-inspired). Brand and material choice matter for fitment, finish quality, and how well parts integrate with factory mounting points and any sensors where applicable.

  • Many exterior styling parts arrive unpainted; always dry-fit them on the car and check clearances and fixing points before committing to paint.
  • After installation, recheck clearances and fasteners after some mileage to catch any rubbing, rattles, or movement early.

Rear Spoilers / Aerofoil — Rear spoilers and aerofoils are fitted to change the look, restore damaged originals, or add downforce and stability where appropriate. Choice of design (ducktail, GT-style wing, active spoiler replacement, etc.) affects stability at speed, weight, and how the part interfaces with the decklid, hinges, and any existing mechanisms.

  • Inspect mounts and brackets carefully; reinforce backing areas where necessary so the spoiler remains stable at speed and does not stress the panel.
  • Consider overall aero balance; large rear wings may require complementary front aero to avoid making the car feel light at the front axle.

Air Ducts & Vents — Air ducts and vents are changed to restore cracked or missing trims, improve cooling to brakes, radiators, or intercoolers, or to alter the look of the car. Correctly designed and fitted parts help ensure airflow goes where intended without adding unnecessary drag or noise.

  • Check that ducts and vents match the bumper and undertray design for your Porsche so mounting points, clips, and hose connections line up properly.
  • Keep duct paths clear of debris and make sure no edges rub on adjacent panels, which can cause paint damage or whistles at speed.

Lighting — Lighting components are replaced or upgraded for better visibility, fresher appearance, reliability, or to meet local regulations. On older Porsches, new lenses and housings also help refresh a tired exterior and reduce issues like condensation and poor beam output.

  • Look out for condensation inside lamps, cracked or cloudy lenses, flickering bulbs, warning lights on the dash, and earth faults that cause unusual lighting behaviour.
  • When upgrading to LED or different-style lamps, ensure compatibility with the vehicle’s electrical system and local road-legal requirements.

Fog/Drive Lamps — Fog and driving lamps are changed to restore low-mounted forward lighting in poor weather, repair stone or impact damage, or upgrade output for night and performance driving. Correctly specified and aligned units improve real-world visibility without adding glare.

  • Check lenses and housings for cracks, moisture, and corrosion, and inspect brackets and wiring near the bumper for damage or chafing.
  • When upgrading, replace seals and confirm that bumper ducting is not directing water into the lamp area to help prevent repeat failures.
