What This Product Does

This panel shields the rear underside against spray, dirt and debris thrown up during driving. As one component of the underbody linings, it also helps maintain the intended airflow beneath the car. 

Functions

  • Closes the rear underside lining area.
  • Reduces direct contact with spray and loose road debris.
  • Reinstates the original arrangement of underside panels.
  • Helps maintain the intended underbody airflow path.

    Technical Details
  • Brand: genuine Porsche.
  • Location: rear underside.
  • Each supplied diagram specifies one cover.
  • Assembly context: Boxster and Cayman underbody linings.

    Symptoms of Fault
  • Visible splitting, cracking or loss of panel sections.
  • A sagging panel making contact with the road.
  • Noise from insecure fasteners or damaged attachment areas.
  • A misshapen cover following an impact with a kerb or obstacle.
  • Debris or spray entering previously covered underside areas.

    Why Replacement Matters

Renewing a missing or damaged cover reinstates the intended underside coverage. A distorted panel may no longer sit correctly, while damaged fixing points can allow movement and rattling. Inspect the neighbouring supports and attachment hardware during replacement: the supplied diagrams identify brackets, nuts and screws as separate components, not as part of this cover.

FAQs

  • Is this the rear panel?
    Yes. Both supplied diagrams identify this component as a rear underbody cover.
  • Does the description confirm included fasteners?
    No fixing kit is specified. Supports and fasteners have separate entries in the diagrams, so confirm the required installation parts.
  • What can damage an undertray?
    Contact with road obstacles, debris or lifting equipment can damage the panel or its attachment points.
  • How do I confirm the correct application?
    Match reference 98750412900 to the vehicle's model, engine, production date and applicable parts diagram. The supplied Cayman S listing begins in 2005, while the Cayman diagram covers 2006–08; confirm the production details before ordering.

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The lining forms the complete section of the original underbody trim assembly. It covers the corresponding area beneath the vehicle, helping limit exposure of adjacent components to water, dirt and road debris while maintaining the intended arrangement of the factory underbody panels.

Functions

  • Restores the section of the underbody lining
  • Provides a barrier against dirt, water and road debris
  • Supports the original underbody panel layout
  • Replaces a cracked, distorted, loose or absent panel

Technical Details

  • Catalogue description: underbody trim, complete
  • Required quantity shown in the diagrams: 1
  • Recorded weight: approximately 1.106 kg

Symptoms of Fault

  • Visible cracking, splitting or sections missing from the lining
  • Loose edges or broken attachment points
  • Rattling or fluttering sounds when the vehicle is moving
  • A warped panel sitting below the surrounding underbody
  • Scraping caused by the trim contacting the road
  • Absent or damaged retaining nuts, screws or clips

Why Replacement Matters

A broken or missing lining exposes the surrounding underside to increased contamination and stone impact. Renewing the panel restores the original coverage and helps prevent loose trim from moving or dragging. Check the mounting locations, expanding nuts and panel bolts during installation, replacing damaged fasteners where necessary so the new lining can be secured correctly.

FAQs

  • Which side is this trim for?
    It is the complete underbody lining identified in the Porsche parts diagrams.
  • Is it listed for both pre-facelift and facelift vehicles?
    Yes. The supplied diagram data includes Cayenne 92A applications up to 2014 and from 2015 onwards within the stated 2010–17 coverage.
  • Are retaining clips and bolts supplied?
    The inclusion of fixings is not specified. Inspect the existing expanding nuts, screws and mounting points before installation.
