Diagram Ref No 11

Application depends on the seat equipment: electric vertical adjustment is required. Left- or right-hand installation is suitable where specified for the fitted mechanism.

What This Product Does

Mounted below the seat’s leading edge, this panel hides the adjustment motor and surrounding mechanism. It finishes the lower assembly and helps limit incidental contact with the covered components. This is a trim cover, rather than a motor or adjustment mechanism.

Functions

• Conceals the motor and adjacent adjustment components.
• Reinstates the lower trim when the original panel is absent or damaged.
• Completes the seat assembly with a satin black finish.

Technical Details

• Brand: genuine Porsche.
• Part identification: 9285217600501C.
• Colour and finish: satin black.
• Location: lower front area of the seat base.
• Seat specification: electrically operated vertical adjustment.
• Installation: either front seat where the applicable mechanism is fitted.

Symptoms of Fault

• Visible cracking, damaged edges or fractured attachment points.
• A missing panel leaving adjustment components exposed.
• Trim movement or rattling when the seat operates.
• A cover that no longer sits correctly after seat work.

Why Replacement Matters

Renewing a missing or broken panel returns the lower seat area to a complete appearance and conceals the adjustment equipment. Inspect the attachment points and confirm the seat specification before fitting. A replacement cover does not correct faults in the motor, runners or electrical connections.

FAQs

Does it suit manually adjusted seats?
The supplied application specifies electric vertical adjustment; do not assume compatibility with manual seats.

Is it left- or right-specific?
Either side may accept this cover where the specified seat mechanism is present.

What should I check before ordering?
Match 9285217600501C against the removed panel and verify the vehicle’s production year and seat equipment.

Check fitment for your specific vehicle (model, year, engine) before ordering.

Front Seat Rail Support

OE Match front seat rail support for early Porsche 911 models. This replacement component is ideal for restoring an original seat installation where the existing support has become corroded, damaged or weakened.

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 11

The support forms part of the front seat mounting arrangement, providing the structure required to correctly locate and support the seat rail assembly.

Two supports are required per vehicle and they are sold individually.

What Does the Front Seat Rail Support Do?

The front seat rail support provides a secure mounting point for the seat rail assembly, helping correctly position and support the front seat within the vehicle.

A sound mounting structure is particularly important because the seat assembly is subjected to repeated loads whenever the vehicle is driven, as well as when the seat is adjusted or occupied.

Why Does It Fail?

On an early Porsche 911, age and corrosion are the main reasons for seat rail support replacement. These cars are now several decades old, and moisture trapped around the floor and seat mounting areas can cause deterioration of the original metalwork.

Replacement may be required because of:

• Corrosion or rust
• Cracked or weakened metal
• Damaged mounting points
• Previous poor-quality repairs
• Accident or floor pan damage
• Distortion around the seat mounting area
• Damage discovered during restoration

Corrosion is a recognised problem with these components; Design911 also offers a later stainless-steel alternative specifically intended to address the corrosion associated with the original carbon-steel design.

When Should It Be Replaced?

The support should be replaced if it is structurally weakened, heavily corroded, distorted or no longer provides a secure mounting point for the seat rail.

It should also be carefully inspected when carrying out:

• Floor pan restoration
• Front seat refurbishment
• Seat rail replacement
• Interior restoration
• Welding repairs around the seat mounting area

Any corrosion around the surrounding floor structure should be repaired before installing the replacement support.

Checks During Replacement

When replacing the seat rail support, also inspect:

• Seat rails and runners
• Surrounding floor pan
• Seat mounting points
• Mounting hardware
• Seat adjustment mechanism
• Opposite seat rail support
• Nearby metalwork for hidden corrosion

Correct seat positioning and alignment should be confirmed before completing any permanent restoration or welding work.

• Porsche 356C 1963-65

Although small, the headrest knob is a prominent interior component that contributes to both the appearance and functionality of your seats. Over decades of use, original knobs can become scratched, corroded, dented or lost during seat refurbishment. Replacing them with a quality OE Match component helps restore the authentic look of your Porsche interior while ensuring smooth and reliable headrest adjustment.

Manufactured from durable stainless steel, this replacement headrest knob offers excellent corrosion resistance, long-lasting durability and an attractive factory-style finish, making it ideal for concours restorations, sympathetic refurbishments and everyday classic Porsche ownership.

What Does the Headrest Knob Do?

The headrest knob forms part of the seat adjustment mechanism, allowing the headrest to be securely adjusted or removed when required. It provides a comfortable grip for operation while maintaining the clean, period-correct appearance of the seat.

Why Replace the Headrest Knob?

Years of regular use and exposure can lead to deterioration of interior hardware. Common reasons for replacement include:

• Scratched or worn finish
• Corrosion or surface pitting
• Dented or damaged knob
• Missing original component
• Seat restoration or upholstery replacement
• Completing a concours-standard interior refurbishment

Replacing worn seat hardware is an effective way to improve both the appearance and usability of your Porsche interior.

Features

• Precision manufactured from high-quality stainless steel
• Corrosion-resistant finish
• Factory-style appearance
• Durable construction for long service life
• Smooth operation of the headrest adjustment mechanism
• Ideal for restoration and refurbishment projects

Black headrest runner trim guides from OE Match for Porsche 911 and 912 seats. These replacement interior fittings are intended for renewing damaged or missing headrest trim during seat repairs or restoration.

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 34

What This Product Does
These trim guides finish the headrest runner openings in the seat backrest. They are individual seat fittings rather than complete headrests, seat runners or adjustment mechanisms.

Technical Details

• Supplied part reference: 90152119300.
• Colour: Black.
• The seat diagrams identify this component as a standard rosette.
• Four are recorded in each supplied diagram; this is an assembly quantity, not confirmation of pack contents.
• Application context: front seats up to 1968, from 1969 onwards, and 1970–73. The 1970–73 entry carries the note “-72”.
• Supplied legacy reference: Diagram ref no 34.

Symptoms of Fault

Detached trim or looseness around the headrest fittings warrants inspection. Check the surrounding fittings as well, rather than assuming the trim guide alone accounts for headrest movement.

Why Replacement Matters
Renewing damaged trim allows a localised seat repair without replacing the entire seat. Matching the existing fitting helps retain a consistent interior appearance during refurbishment.

FAQs

Can the existing seat be repaired?
Often, individual seat fittings can be renewed. Inspect the headrest and its mounting points to establish which components need attention.

What should I compare before fitting?
Check the original reference, seat specification and production-year notes. Confirm the colour and required quantity against the parts being removed.

Inner cover seat recliner mechanism. 
This OE Match inner cover is a replacement trim component designed for the seat recliner mechanism on classic Porsche 911 and 912 models 1968. It fits over the internal seat hinge mechanism and restores the original appearance and protection of the seat recliner assembly. This OE Match part is manufactured to replicate the original Porsche design for proper fit and period-correct interior restoration.
Sold as a pair for one seat - 2 pairs required per car

Fits:
Porsche 911 / 912 - 1968

Diagram ref no 26

The inner cover shields the seat recliner mechanism from dirt and debris while also improving the appearance of the seat hinge area. By enclosing the mechanism, it helps protect internal moving components and ensures the seat adjustment system operates smoothly without obstruction.

Replacing worn covers helps restore the original interior finish of classic Porsche seats and prevents further damage to the recliner mechanism.

Seat recliner covers are often exposed to wear from seat movement, UV exposure and aging plastics. Over time they may crack, break or become brittle, leaving the recliner mechanism exposed. Installing a new OE Match cover restores the original look of the interior and protects the seat adjustment mechanism from damage.

Replace the recliner mechanism cover if you notice:
•  Cracked or broken seat hinge covers
•  Missing trim around the seat recliner mechanism
•  Loose or exposed seat hinge hardware
•  During interior restoration or seat refurbishment

Knob For Seat Runner Adjustment, Black.
The OE Match Knob for Seat Runner Adjustment, Black is a replacement seat adjustment knob for early classic Porsche 911 2.0–2.4 models from 1963 to 1973.

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 24

The knob forms part of the manual seat runner adjustment mechanism and provides the hand-operated contact point used when releasing or adjusting the seat position. Finished in black, it is designed to replace an original knob that has become worn, cracked, damaged or missing.

As a small but frequently handled interior component, replacing a deteriorated seat runner knob helps restore both the function and appearance of the seat adjustment system.

What This Product Does:
The seat runner mechanism allows the seat to slide forwards and backwards so the driver or passenger can achieve a suitable seating position.

The adjustment knob provides a comfortable and secure surface for operating the seat runner release mechanism. When used, it helps disengage the runner locking system so the seat can be moved along its rails before locking securely into the chosen position.

Its functions include:

• Providing a convenient hand grip for seat adjustment
• Helping operate the seat runner release mechanism
• Allowing the seat to move forwards and backwards
• Supporting correct driving and passenger seating position
• Protecting the underlying adjustment lever or mechanism
• Restoring the original appearance of the seat hardware

Symptoms Of Wear Or Failure:
Seat adjustment knobs can deteriorate through repeated use, age and general interior wear. Common signs that replacement may be required include:

• Cracked or split knob
• Missing sections of the knob
• Loose fit on the adjustment mechanism
• Knob pulling off during use
• Worn or damaged mounting point
• Smooth or heavily worn surface making it difficult to grip
• Seat adjustment becoming awkward because the knob is missing
• Visible scratches, fading or deterioration
• Knob no longer remaining securely attached
• Exposed metal lever or adjustment mechanism

A stiff or jammed seat runner is not necessarily caused by the knob itself. The rails, locking mechanism and associated hardware should also be inspected if the seat is difficult to move.

Why Replacement Matters:

• Although small, the seat runner adjustment knob is the component the user directly handles when changing the seat position.
• A cracked, loose or missing knob can make the seat adjustment mechanism uncomfortable or difficult to operate and may leave the underlying lever exposed. Continued use of a damaged knob can also cause it to break completely or detach from the adjustment mechanism.
• Replacing the knob restores a secure gripping surface and makes routine seat positioning easier. Maintaining proper seat adjustment is important for achieving a comfortable and appropriate driving position and for allowing different drivers to correctly position themselves relative to the pedals and steering wheel.
• For classic Porsche restoration projects, a correct black replacement knob also helps restore the factory appearance of the interior and replaces a frequently worn detail.
