Black Aluminium Door Threshold Side Sill Protectors

Protect your Porsche's interior while restoring the original factory appearance with these OE Match Black Aluminium Door Threshold Side Sill Protectors Manufactured to replicate the original factory specification, this complete kit includes both the left-hand and right-hand door threshold protectors, providing a factory-style appearance while protecting the painted door sills from everyday wear.


Fits:

  • Porsche 911 1965-1968 2.0L / 912 SWB (F)
  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)  

Diagram ref no 33

Finished in black anodised aluminium, these threshold trims protect the painted door sills from scuffs, scratches and everyday wear while adding a smart, factory-correct finishing touch to the cabin. Ideal for restoration projects or replacing worn original trims, they help preserve both the appearance and value of your classic Porsche.

Kit Contents

This complete OE Match kit includes:

  • 1 × Left-hand black aluminium door threshold side sill protector.
  • 1 × Right-hand black aluminium door threshold side sill protector.

A convenient and cost-effective way to replace both sill protectors together for a consistent factory-fresh appearance.

What Do the Door Threshold Side Sill Protectors Do?

Door threshold protectors are designed to shield one of the highest wear areas of the vehicle.

Their primary functions include:

  • Protecting the painted door sill from scratches and scuff marks.
  • Reducing wear caused by entering and exiting the vehicle.
  • Providing a durable protective surface over the sill panel.
  • Enhancing the appearance of the interior door opening.
  • Delivering the original factory-style finish expected on early Porsche 911 models.

These trims not only improve appearance but also help preserve the bodywork beneath.

Why Do Door Threshold Protectors Fail?

After years of regular use, the original sill protectors can become damaged through constant foot traffic and exposure.

Common causes of deterioration include:

  • Scratches and abrasion from footwear.
  • Dents caused by impacts or heavy objects.
  • Fading or wear of the black anodised finish.
  • Corrosion from trapped moisture.
  • Distortion during removal or previous repairs.
  • Loose or damaged mounting points.

Worn threshold trims can significantly detract from the appearance of an otherwise well-maintained or restored interior.

When Should They Be Replaced?

Replacement is recommended when:

  • The aluminium trim is scratched, dented or corroded.
  • The original finish has faded or worn away.
  • The protectors have become loose or damaged.
  • Completing a full interior or body restoration.
  • Repainting or repairing the door apertures.
  • Returning the vehicle to factory-correct specification.

Replacing worn sill protectors provides an immediate improvement to the appearance of the vehicle while protecting newly painted bodywork from future damage.

Manufactured from premium automotive-grade EPDM rubber, the protector strips are engineered to withstand repeated foot traffic, UV exposure, moisture, road salt and temperature extremes without cracking, hardening or fading. Precision-extruded to replicate the original Porsche profile, they provide direct OE-style fitment and are supplied as a pair, making them ideal for complete restoration projects or replacing worn, damaged or missing originals.

What This Product Does:
  • Protects the door entry and threshold areas from scuffs and scratches.
  • Helps preserve the painted finish of the side sills.
  • Reduces wear caused by repeated entry and exit.
  • Restores the original appearance of the door opening.
  • Provides a cushioned protective surface.
  • Resists moisture, dirt and everyday abrasion.
  • Provides factory-style fitment and finish.
  • Forms an essential part of the vehicle's door entry trim system.

Symptoms Of Wear Or Failure:
  • Cracked, split or hardened rubber.
  • Loose or detached protector strips.
  • Faded or deteriorated appearance.
  • Missing sections of the rubber strip.
  • Exposed painted door thresholds.
  • Increased scuff marks and scratches on the sill.
  • Shrinking or distorted rubber.
  • Poor fit against the bodywork.
  • Reduced protection from everyday wear.
  • Diminished originality during restoration.

Why Replacement Matters:
  • The door entry protector strips are continually exposed to foot traffic, moisture, sunlight and daily wear. Over time, the rubber can harden, crack or become detached, reducing its ability to protect the painted threshold from abrasion and damage.
  • Worn or missing protector strips leave the door entry area vulnerable to scratches, paint damage and corrosion, particularly on classic Porsche models where preserving the original bodywork is essential. Damaged trim can also detract from the appearance and value of the vehicle.
  • Replacing worn or damaged rubber door entry protector strips restores the original level of protection while maintaining the authentic factory appearance of the interior and bodywork. The OE Match replacements provide factory-style fitment, premium EPDM rubber construction and long-lasting durability, making them the ideal solution for Porsche restoration, repair and preventative maintenance.

The carpet retainer secures and finishes the edge of the carpet where it meets the door opening. It helps hold the carpet neatly in place, protects the carpet edge from wear, and provides a clean aluminium trim finish along the inner sill / doorway area.

Carpet retainer just inside the door - Black finish (ribbed)
This Carpet Retainer is an OE-style interior trim strip designed to secure and finish the edge of the carpet along the door sill area in classic Porsche models. Designed for left or right-side fitment, the retainer integrates seamlessly with the vehicle’s interior trim and is typically used in pairs for a complete installation.
Sold each.

Fits:
Porsche 911 1965 - 1989
Porsche 964 >>1990

This OE match carpet retainer is a direct replacement for the original Porsche sill trim strip used in 911 and early 964 models. Installed just inside the door opening, it holds the edge of the interior carpet firmly in place while providing a clean, finished transition between the carpet and door threshold.

Manufactured in a black ribbed finish, this version replicates the factory appearance used in many models, offering both durability and period-correct styling. The ribbed aluminium construction ensures strength while maintaining a lightweight design.

This trim strip secures the carpet edge along the sill, preventing lifting, fraying, or movement. It also enhances the visual finish of the interior by covering raw carpet edges and providing a neat, factory-correct appearance.

Function
Secures carpet edges along the door sill
 Prevents carpet movement, lifting, or fraying
 Provides a clean and finished interior edge
 Protects carpet from wear at entry points
 Enhances interior appearance with OE-style trim

Carpet retainers are exposed to frequent foot traffic and can become scratched, loose, or corroded over time. A worn or missing retainer can allow the carpet to shift or fray, detracting from the interior’s appearance. Replacing it restores both functionality and the original factory look.

When to replace
  Carpet edge is loose or lifting
  Retainer is scratched, bent, or corroded
  During interior restoration or carpet replacement
  Missing or incorrectly fitted trim strip
  Visible wear in door entry areas

  • Damaged or missing sill covers leave the painted door aperture vulnerable to wear and corrosion while detracting from the appearance of the vehicle. On restored or concours-quality cars, worn sill trim can significantly reduce the overall presentation and value of the interior.

Why Replacement Matters:

  • A worn or missing sill protector leaves the door threshold vulnerable to scuffs, scratches and corrosion, particularly on classic Porsche models where preserving the original bodywork is essential. Damaged trim can also detract from the vehicle's appearance and originality, reducing its overall presentation and value.
  • Replacing worn or damaged door threshold side sill protectors restores the factory finish while protecting the painted sill from further wear. The OE Match replacements provide precise OE-style fitment, premium-quality construction and long-lasting durability, making them an excellent choice for Porsche restoration, repair and preventative maintenance.

Plastic Expansion Rivet for Door Sill Step Plate
This Porsche Genuine OE Expansion Rivet is a factory plastic push-type fastening clip designed for securing the door sill step plate / threshold trim. Commonly referred to as a plastic rivet, expanding rivet, or trim clip, this component is widely used in classic Porsche models for fastening interior and exterior trim panels.
Sold individually, Typically multiple required per vehicle

Fits:
Porsche 911 1965 - 1973
Porsche 914 1970 - 1976

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.

About Side Sill Trims

Porsche Side Sill & Step Trims | Precision Interior & Exterior Finishing Components

Side sill and step trims are the finishing touch that bridge style and protection in your Porsche’s design. These trims protect the lower door openings and sill areas from scuffs, scratches, and dirt while adding a polished, premium appearance to your interior and entryway. Over time, constant use and exposure to the elements can cause damage or fading — making replacement essential for maintaining your Porsche’s visual and structural integrity.

At Design911, we supply high-quality side sill and step trims crafted to meet or exceed original specifications. Manufactured from durable materials such as aluminium, stainless steel, or carbon fibre, our trims ensure perfect fitment, long-term protection, and an elegant aesthetic.

Whether you’re restoring a classic 911 or upgrading a modern Cayenne, our sill trims combine functional protection with refined Porsche styling.

What Do Side Sill / Step Trims Do?

Side sill and step trims serve both protective and aesthetic roles in your Porsche, combining practicality with design excellence.

  • Prevent corrosion and wear in high-traffic entry points.

A properly fitted sill trim maintains the sleek, premium appearance Porsche interiors are known for while safeguarding bodywork.

Damaged or faded sill trims not only detract from your Porsche’s appearance but can also allow moisture to penetrate, leading to corrosion or further wear.
