Side Sill Seals
By OE Match
- Porsche 356A 1955-59
- Porsche 356B 1959-63
- Porsche 356C 1963-65
The kit includes four precision-formed aluminium strips that fit directly into the door sill areas on both sides of your Porsche 356. These threshold trims mount over the carpet at the lower door openings, offering a classic polished look that matches the vehicle’s original styling.
Fits:
Porsche 356 Speedster / Roadster 1950 - 1965
Diagram ref no 53 and 59
This kit includes two wide and two narrow aluminium strips to cover both door entry sills on your vehicle.
Threshold kit includes:
- 2 Wide aluminium strips (OE ref no 64455111700)
- 2 Narrow aluminium strips (OE ref no 64455111900 / 64455112000)
The aluminium door sill threshold strips serve both a protective and aesthetic function. They shield the painted door sill and interior carpet edge from scratches, shoe marks, and general wear during vehicle entry and exit. In addition, the metal finish restores the classic look and feel of a well-preserved or restored Porsche 356, providing a high-quality finishing touch to the cabin threshold.
Function
• Protects the door sill paint and carpet edges from abrasion.
• Provides a classic polished trim finish consistent with original Porsche design.
• Fits flush with the sill area for clean, restoration-ready aesthetics.
• Durable aluminium construction resists wear and moisture exposure common in classic cars.
Door sill areas on classic Porsche 356 cars receive heavy foot traffic, which can easily wear away paint, rust bare metal, and fray the carpet edge. Without proper threshold protection, dirt and moisture can also lead to corrosion over time. Installing this aluminium sill threshold kit restores classic styling, protects vulnerable surfaces, and preserves interior value - especially important for restorations or classic-car presentations.
Replace your door sill trims if:
• The existing aluminium strips are worn, dented, or corroded
• Paint or carpet edges show scratches and abrasion
• You’re performing an interior restoration or detailing refresh
• Moisture has caused rust or surface degradation around the sill area

Whether you are completing a concours restoration or replacing damaged original trim, this OE Match rocker panel moulding helps return your Porsche 356 to its authentic factory appearance.
What Does the Rocker Panel Moulding Do?
The rocker panel moulding is an exterior trim component fitted along the sill (rocker panel) beneath the doors.
Its primary functions include:
- Enhancing the classic styling of the Porsche 356.
- Providing a clean, factory-correct finish to the rocker panel.
- Concealing panel joints and fixing points.
- Helping protect the sill edge from minor scuffs and stone chips.
- Completing the authentic appearance of the bodywork.
- Maintaining the original Porsche design lines.
Although primarily decorative, the rocker panel moulding plays an important role in the overall presentation and originality of the vehicle.
Why Should the Rocker Panel Moulding Be Replaced?
After decades of use, original mouldings can deteriorate due
to age and environmental exposure. Common reasons for replacement include:
- Corrosion or pitting.
- Dents caused by road debris or incorrect lifting.
- Scratches and impact damage.
- Loss of shine through age.
- Distortion from previous repairs.
- Missing or damaged trim during restoration.
- General deterioration affecting the vehicle's appearance.
Replacing worn mouldings significantly enhances the overall finish of a restored Porsche 356.
When Should the Rocker Panel Moulding Be Replaced?
Replacement is recommended whenever:
- Restoring the vehicle to factory condition.
- Repainting the body.
- The original moulding is damaged or corroded.
- Trim has become loose or distorted.
- Completing a concours-quality restoration.
- Replacing missing exterior trim.
Installing new mouldings during body restoration ensures the finished vehicle achieves the correct factory appearance.

The OE Match mounting strip is a U-shaped metal mounting channel designed for the door step threshold rubber seal on Porsche 356 models. This component sits beneath the rubber door threshold seal and helps hold it securely in place along the door opening.
Sold each, 2 required per car (one for each door)
Fits:
Porsche 356 - 1950 to 1955
Porsche 356A - 1955 to 1959
Porsche 356B - 1959 to 1963
Porsche 356C - 1963 to 1965
U-shaped, metal threshold rubber seal mounting strip finished in stove enamelled, gloss black
Diagram ref no 26
The mounting strip supports the door threshold rubber seal and ensures it stays firmly attached to the body.
By holding the seal securely, it helps prevent movement, protects the sill area and contributes to a clean and finished appearance of the door opening.
Replacing worn or corroded mounting strips restores the proper installation of the threshold rubber and helps maintain the integrity of the door sill trim.
Function
• Seal Retention: Holds the door threshold rubber seal securely in place
• Mounting Support: Provides a metal channel for attaching the rubber step seal
• Body Protection: Helps protect the door sill area from wear and moisture
• Restoration Fit: OE-style design ensures correct installation in classic Porsche 356 models
Threshold mounting strips are exposed to moisture, road dirt and decades of use. Over time they may corrode, bend or lose their ability to hold the rubber seal correctly. Replacing them ensures the door threshold rubber remains properly secured and helps preserve the original appearance and protection of the door sill area.
Consider replacing the mounting strip if you notice:
• Loose or poorly fitted door threshold rubber seal
• Corrosion or damage to the metal channel
• Missing or bent mounting strips
• During interior or body restoration of a Porsche 356

OEMatch Side Sill Seals — Fit, Finish, Clarity
Side sill seals form a protective barrier along the door threshold and lower body, keeping water, grit and road debris away from the sill cavity and cabin. OEMatch supplies a selection of rubber sill seals for Porsche models suitable for restoration, repair and routine maintenance.
Available Types- Extruded EPDM profiles for continuous sill runs
- Pre-formed sill weatherstrips shaped for specific model contours
- Adhesive-backed edge seals and trim pieces for local repair
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original side sill seals.
OE (Original Equipment) refers to parts matching original specifications for the side sill seals and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM side sill seals engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Fitted along the sill flange and door threshold, these seals block moisture and contaminants, limit wind noise and support door sealing. Correct material resistance, section profile and secure attachment are important for lasting performance.
- Prevents water ingress and sill cavity corrosion
- Reduces wind noise and vibration at the door threshold
- Protects paint edges and interior trim from grit and moisture
- Supports consistent door sealing and cabin comfort
- Prolonged UV and ozone exposure causing hardening or cracking
- Repeated compression from door closing leading to fatigue
- Abrasion from trapped dirt and road debris
- Misalignment, damaged mounting channels or corroded sill flange reducing contact
Replacing degraded sill seals reduces the risk of water entering the bodywork and helps prevent corrosion that can spread to structural areas. New seals restore acoustic insulation and maintain door fit and weatherproofing, contributing to long-term preservation of Porsche body panels.
Advantages- Made from weather-resistant rubber compounds such as EPDM
- Retains flexibility and sealing contact across normal temperature ranges
- Available in pre-formed and extruded profiles to suit specific model contours
Fitting can appear straightforward but may require specific procedures such as correct positioning, sealing detail and careful reassembly to avoid panel damage. If you lack the right tools or experience, or if the vehicle includes hidden fasteners or sensors, seek professional installation. Recheck fasteners and seal compression after initial use.
