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.
Fits:
- Porsche 928 S4 5.0L 1987-92

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
