Diagram ref no 29
It replaces earlier reference 99959152640 and is supplied individually.
This is a multi-use trim fastening clip, also used in other interior applications depending on model and configuration.
This expansion rivet is inserted into pre-drilled holes and expands when pushed into place, locking the door sill plate or trim strip securely to the bodywork.
It provides a firm hold while allowing easy installation and removal, making it ideal for trim components that may require periodic servicing or replacement.
Functions & Technical Role
• Trim fastening: Secures door sill step plates and threshold trims
• Expansion locking design: Expands inside mounting holes for secure retention
• Vibration resistance: Prevents movement, rattling, or loosening of trim
• Non-corrosive material: Plastic construction resists rust and environmental damage
• OEM precision: Designed to Porsche specifications for correct fit and grip
Fitment / Position on car
• Fitting position: Interior / body trim
• Location: Door sill step plates (threshold trims) / Rocker panel trim strips / Interior trim panels (various applications)
Trim clips are often overlooked but are critical for maintaining proper fit and finish. Over time, they can:
• Become brittle or break
• Lose tension and fail to hold trim securely
• Be lost during removal or restoration work
A worn or missing rivet can lead to:
• Loose or rattling sill trims
• Poor alignment of interior panels
• Reduced overall finish quality
Replacing with genuine Porsche OE rivets ensures secure trim mounting and preserves the original appearance of the vehicle.
