This OE Match Interior Door Panels Cardboard Replacement Set is a pair of OE-style replacement backing panels designed for Porsche 911 and 964 models. These panels form the structural base of the interior door trim assembly.
Supplied as a left and right pair (SET OF 2), these replacement boards are ideal for full interior refurbishment or restoration of classic Porsche interiors.

These replacements are precision cut with the correct openings and mounting points for handles, switches, speakers, and trim attachments. The panels are supplied without vinyl covering, making them ideal for restoration projects, custom trimming, or reusing original upholstery material.

These replacement door panel boards provide the structural backing for the interior door trim assembly. They support the upholstery material and mounting hardware while restoring the correct shape, fitment, and rigidity of the door panels.

Function
• Provides structural backing for interior door trim panels
• Restores correct door panel shape and rigidity
• Supports attachment of handles, pockets, and trim components
• Eliminates sagging or warped original door cards
• Maintains proper alignment and fitment of interior trim

Original Porsche door panel backing boards often deteriorate due to age, moisture exposure, and repeated stress from door operation. Warped or weakened panels can cause loose trim, rattles, poor fitment, and an untidy interior appearance. Replacing the backing boards restores structural support, improves fitment, and helps maintain the original interior quality of the vehicle.

When to replace
•  Door panels are warped, sagging, or swollen
•  Interior trim no longer fits correctly
•  Moisture damage or deterioration of original backing boards
•  Loose mounting points or rattling door panels
•  During full interior restoration or retrimming
