The Genuine Porsche Front Bumper Corner Panels (Part Numbers: 99150557300 and 99150557400) are original equipment exterior bodywork components designed for selected Porsche 911 (991.1) Turbo, GT3 RS models.

Fits:

  • Porsche 991.1 Turbo 3.8L (520 Bhp) 2014-16
  • Porsche 991.1 Turbo S 3.8L (560 Bhp) 2014-16

Diagram Ref No 18

These position-specific corner panels form part of the front bumper covering and trim assembly, providing the correct finishing and supporting arrangement at the corresponding left-hand and right-hand bumper corners.

The two available versions are:

99150557300 – Left-Hand Front Bumper Corner Panel

99150557400 – Right-Hand Front Bumper Corner Panel

The Porsche 991.1 front bumper is made up of several individual components, including the main bumper cover, air inlet grilles, air guides, spoiler sections, retaining plates and associated mounting hardware.

The corner panels form part of this assembly and help complete the intended bumper construction.

Manufactured to Porsche's original equipment specifications, each corner panel is shaped to match its designated mounting position and the surrounding bodywork components.

Correct fitment is important for maintaining the original alignment and appearance of the bumper assembly.

On high-performance Porsche 911 models such as the Turbo, GT3 and GT3 RS, the front bumper incorporates carefully designed air inlets, trim sections and aerodynamic elements.

Although these corner panels are not primary aerodynamic devices, they form part of the factory bumper construction and help maintain the intended arrangement of neighbouring components.

The front bumper is exposed to stones, road debris, kerb contact, parking impacts and general wear.

Over time, corner panels may become scratched, cracked, distorted or detached because of minor impacts, damaged retaining points or previous incorrect repairs.

A damaged corner panel may no longer sit correctly within the bumper assembly, potentially leaving uneven gaps or allowing unwanted movement.

Replacing a damaged panel with a Genuine Porsche component helps restore the original bumper configuration, maintain correct component alignment and preserve the factory appearance of the vehicle.

What This Product Does:
The front bumper corner panel is a bodywork component fitted within the designated left-hand or right-hand section of the front bumper assembly.

Its primary function is to complete the corresponding bumper corner arrangement and provide the intended interface with surrounding trim and mounting components.

The panel forms part of the original bumper construction and must remain correctly positioned to maintain secure fitment.

Its main functions include:

  • Completing the front bumper assembly: Provides the specified corner component for the original Porsche bumper.
  • Maintaining correct panel alignment: Helps preserve the intended positioning of neighbouring bumper parts.
  • Supporting secure trim installation: Works with the relevant retaining hardware and surrounding components.
  • Providing a finished bumper corner: Maintains the correct exterior bodywork configuration.
  • Preserving factory styling: Supports the original front-end appearance of the Porsche 991.1.
  • Maintaining left- and right-hand symmetry: Provides the correctly shaped component for each side.
  • Supporting bumper refurbishment: Allows damaged corner sections to be replaced individually.
  • Reducing unwanted component movement: Helps maintain the specified fit when correctly secured.
  • Supporting neighbouring aerodynamic components: Maintains the original assembly arrangement around the front spoiler and air inlet sections.
  • Preserving original construction: Provides the factory-designed component for the applicable bumper configuration.

Symptoms Of Wear Or Failure:
The front bumper corner panel does not contain moving mechanical or electrical parts.

Damage is generally identified through physical deterioration, incorrect fitment or insecure mounting.

Common signs of a damaged front bumper corner panel include:

  • Visible cracking: Impact damage or mechanical stress may cause cracks.
  • Broken mounting points: Damaged attachment features may prevent secure installation.
  • Loose corner panel: The component may move within the bumper assembly.
  • Uneven bumper gaps: A distorted panel may no longer align correctly with neighbouring trim.
  • Scratches and scuff marks: Road debris or minor contact may damage the surface.
  • Distorted panel shape: Collision damage or incorrect handling may deform the component.
  • Partial detachment: Damaged fasteners or retaining points may allow the panel to separate from the bumper.
  • Missing corner panel: Previous damage or repairs may leave the assembly incomplete.
  • Rattling noises: An insecure panel may vibrate against adjacent bodywork.
  • Damaged retaining hardware: Broken rivets or missing fasteners may compromise attachment.
  • Visible impact marks: Damage may be apparent after kerb or parking contact.
  • Poor fitment following bumper removal: Incorrect reassembly may leave the corner panel improperly positioned.
  • Gaps around surrounding trim: A damaged mounting interface may affect the fit of nearby bumper components.
  • Abrasion marks: Movement against neighbouring panels may create surface wear.
  • Damaged edges: Cracked or broken edges may prevent the panel from seating correctly.
  • Evidence of previous accident repairs: Non-original fasteners or distorted mounting surfaces may indicate an incorrectly repaired assembly.

Why Replacement Matters:
Replacing a defective front bumper corner panel helps maintain the original fitment and appearance of the Porsche 991.1 front bumper.

A cracked, distorted or partially detached panel may no longer provide a secure connection within the bumper assembly.

Continued use with damaged mounting points may allow additional movement, potentially affecting neighbouring trim components.

Where the main bumper cover remains serviceable, replacing the individual corner panel can provide a targeted repair without replacing the entire bumper assembly.

Installing a Genuine Porsche replacement Front Bumper Corner Panel helps to:

  • Restore correct bumper fitment: Replace a damaged component with the specified original part.
  • Maintain factory panel alignment: Help surrounding bumper components sit in their intended positions.
  • Restore exterior appearance: Replace cracked, scratched or missing corner sections.
  • Improve mounting security: Renew panels with broken retaining features.
  • Reduce unwanted movement: Address loose components that may vibrate during driving.
  • Prevent further trim damage: Repair defective mounting interfaces before surrounding components deteriorate.
  • Support front bumper repairs: Provide the correct part during bumper refurbishment.
  • Maintain original bumper construction: Preserve Porsche's intended assembly arrangement.
  • Support accident restoration: Replace damaged parts following minor impacts.
  • Preserve factory styling: Maintain the distinctive front bumper design of the applicable Porsche model.
  • Avoid unnecessary bumper replacement: Renew an individual component where the main bumper remains undamaged.
  • Maintain Genuine Porsche quality: Use a factory-specified replacement component.
  • Support long-term exterior maintenance: Restore secure and correctly aligned bodywork.

Replacement is recommended when the panel is cracked, distorted, missing or unable to remain securely attached.

If the surrounding bumper structure or mounting hardware is damaged, those components should also be repaired or replaced.

What This Product Does:

  • Provide aerodynamic shaping at the front bumper corners
  • Help guide airflow around the front of the vehicle
  • Support stability and reduce turbulence at speed
  • Protect the lower bumper edges from minor scuffs and road debris
  • Restore factory bumper appearance and correct OEM fitment

Symptoms Of Damage Or Wear:
  • Cracks or breaks from kerb/parking impact
  • Scratched or heavily worn black finish
  • Missing spoiler after accident repair
  • Loose fitment, rattling, or broken mounting tabs
  • Uneven appearance between left and right sides

Why Replacement Matters:
  • Restore OEM front-end styling and clean bumper lines
  • Maintain correct aerodynamic trim fitment
  • Prevent loose parts from vibrating or coming off at speed
  • Protect the bumper corners and surrounding trim
  • Improve overall vehicle presentation and resale condition
