Undertray Repair Support Kit – Strong, Cost-Effective Undertray Fix
Has your Porsche belly pan or bottom plate developed broken
or cracked mounting supports? This is a common issue we regularly see in our
Design911 workshop. Over time, road debris, speed bumps, improper jacking, and
general wear can cause the original undertray mounting points to snap or
weaken.

Repair kit for diagram ref no 27
Instead of replacing the entire belly pan – which can be expensive – our heavy-duty Porsche belly pan repair support kit provides a simple, strong and long-lasting solution.
What These Repair Supports Do
The original plastic mounting tabs on Porsche undertrays are
prone to failure. When they break, the belly pan can sag, vibrate, or become
loose, affecting:
• Underbody protection
• Aerodynamics
• Cooling airflow management
• Overall vehicle stability at speed
Our 3D laser-printed nylon repair supports reinforce and replace the failed mounting points. They restore secure attachment of the bottom plate to the chassis, preventing further damage and eliminating rattles or movement.
Why Upgrade to This Repair Kit?
Cost Saving Alternative
A brand-new Porsche belly pan or undertray panel can be costly. This repair kit
allows you to fix only the damaged support areas instead of replacing the full
panel.
Stronger Than Original
Manufactured from high-strength, flexible 3D laser-printed nylon, these
brackets are designed to be more durable than the factory mounting tabs. They
resist cracking, vibration fatigue, and road impact stress.
Workshop-Proven Solution
Developed after repeatedly seeing broken undertray supports in our own
workshop, this kit is a practical, real-world tested fix trusted by Porsche
specialists.
Complete Installation Hardware Included
Each set includes 8 nuts, bolts and washers per side, ensuring secure fitment
and straightforward installation.
Ideal For:
• Porsche owners with cracked or broken undertray mounts
• Vehicles with sagging belly pans
• Performance or track cars exposed to higher underbody stress
• Preventative upgrades when replacing or servicing the under

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

- 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.
