The incredible Lightweight Bucket Seats from Porsche adorn many vehicles from the 918 to the GT3, GT2, GT4, T and many other models if so equipped. 

We created this adjustable lumbar support for our vehicles out of necessity. Not only for the driver but the passenger who agreed to that 6 hour journey as our co-pilot. Typically these are quite comfortable seats but on longer journeys, a little lumbar support goes a long way to comfort the back of you and your co-pilot. 

These install in a minute for each side, adjustable for height (lower back, small of back, etc)

The air bladder is adjustable via a simple and lightweight ball pump and once the desired support is obtained, the ball pump can be removed and the hose and check valve tucked into the seat for an invisible install. Or just keep the ball for adjustment at anytime.

Foam cushion for the front seat backrest (inner).

Sold individually; fits either side.

Porsche Motorsport Backrest padding inserts for the driver racing bucket seat
It allows drivers to adjust the thickness and ergonomic fit of the seat's back support during track configurations
• Thickness: 20 mm
• Application: Porsche Motorsport bucket racing seats

Fits:
Porsche 992.1 GT3 CUP 4.0L Model 2021

Diagram ref no 04

What This Product Does

This padding component sits in the backrest of the Porsche Motorsport racing bucket seat. Its specified thickness contributes to the driver's ergonomic fit when configuring the seat for track use. It is backrest padding, not a replacement bucket seat.

Functions

• Cushions the driver's back within the racing seat.
• Provides a 20 mm padding option for configuring back support.
• Allows replacement of the backrest padding as a separate seat component.

Technical Details

• Brand: Porsche Motorsport.
• Thickness: 20 mm.
• Application: driver backrest in Porsche Motorsport bucket racing seats.

Symptoms of Fault

Inspect the padding if it has become compressed or shows visible deterioration. Confirm that the backrest insert is responsible for an unsuitable seating feel before replacing other components.

Why Replacement Matters

Replacing deteriorated backrest padding addresses cushioning wear without requiring a complete seat replacement. Check the insert position and thickness against the intended driver seating configuration; shoulder, rib and sitting-cushion inserts are distinct components.

FAQs

Is this a complete racing seat?
No. This component is the 20 mm backrest padding insert.

What should be checked before fitting?
Confirm the bucket-seat application, required backrest thickness and relevant part reference. Do not substitute a shoulder insert solely because it belongs to the same seat assembly.

Before ordering, confirm compatibility with your vehicle's model, production year and engine.

Diagram ref no 06

What This Product Does

This insert provides padding at the front of the driver seat. It is an individual component within the seat assembly, rather than a complete seat or a full padding set.

Functions

• Provides cushioning in the front seat position.
• Allows renewal of the corresponding padding component without replacing the complete seat.

Technical Details

• Porsche part number: 9F1881441E.
• Application designation: Porsche MOTORSPORT 
• Position: Front, within the driver seat assembly.
• Insert specification: S 40MM.

Symptoms of Fault

Collapsed or visibly deteriorated seat padding can indicate that the insert needs inspection. Check the affected component before deciding which seat part requires renewal.

Why Replacement Matters

Renewing damaged padding addresses cushioning wear while retaining the existing seat assembly. Match the Front position and S 40MM specification; shoulder, rib, backrest and sitting-cushion inserts are separate components.

FAQs

Must the complete seat be replaced?
Not necessarily. An individual padding insert can be renewed when the remaining seat components are serviceable.

How should the correct insert be identified?
Compare part number 9F1881441E, the Front position and S 40MM specification with the applicable driver-seat diagram.

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

What This Product Does

This insert provides padding at the pelvic area within the Cup driver's seat. It is an individual seat component rather than a complete seat, seat shell or adjustment mechanism.

Functions

• Provides cushioning around the driver's pelvic area.
• Allows renewal of this padding component without replacing the complete seat.

Technical Details

• Porsche part number: 9F1881441T.
• Size designation: S.
• Specified thickness: 30MM.
• Assembly location: driver seat, pelvic area.

Why Replacement Matters

Renewing worn seat padding can address cushioning-related comfort issues while retaining the existing seat assembly. Confirm the S designation and 30MM specification against the required insert; shoulder, rib, backrest and sitting-cushion padding are separate components.

FAQs

Does a padding repair require a complete replacement seat?
Not necessarily. Individual padding components can be renewed where the remaining seat assembly is suitable for continued use.

What should be checked before fitting?
Confirm the vehicle application, seat assembly and part number, together with the required padding size and thickness. Follow the manufacturer's fitting instructions.

The insert provides padding at the rib area within the driver seat assembly. It is a separate seat component rather than a complete seat, shoulder pad or sitting cushion.

Functions

• Provides cushioning around the driver's rib area.
• Allows the rib padding to be renewed as an individual seat component.
• This specialized foam insert allows racing drivers to customize the fitment of their bucket seat around the rib cage/torso area for optimal support, safety, and comfort under high G-forces.

Technical Details

• Part number: 9F1881441P.
• Application: motorsport driver seat.
• Size designation: S.
• Specified padding thickness: 30MM.
  
  

Symptoms of Fault

Collapsed padding or reduced cushioning can indicate that the seat insert needs inspection. Confirm which padding component is affected before selecting a replacement.

Why Replacement Matters

Renewing a worn insert addresses localised cushioning deterioration without replacing the entire seat. Match the part number, size designation and thickness to the required driver seat configuration; shoulder, backrest, pelvic and sitting pads are distinct components.

FAQs

Is this a complete driver seat?
No. It is the rib-area padding insert within the driver seat assembly.

Does this replace the shoulder padding?
No. The exploded diagram identifies shoulder inserts separately from the rib insert.

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

Porsche Motorsport Shoulder padding inserts for the driver racing bucket seat
Custom modular padding adjustment for racing bucket seats to alter driver snugness and impact absorption at the shoulders.
• Size / Thickness: Size S / 30 mm
• Application: Porsche Motorsport bucket racing seats

Fits:
Porsche 992.1 GT3 CUP 4.0L Model 2021

Diagram ref no 01

What This Product Does

The insert provides padding at the shoulder area of the driver's seat. It is an individual component within the seat assembly, rather than a complete seat or seat shell.

Functions

• Provides shoulder-area cushioning within the driver seat.
• Allows renewal of the specified padding component without replacing the complete seat.

Technical Details

• Porsche part number: 9F1881441K.
• Application: driver-seat shoulder padding
• Size designation: S.
• Specified thickness: 30MM.

Symptoms of Fault

Collapsed or visibly damaged padding can indicate that the shoulder insert needs inspection. Check the insert itself before attributing discomfort or reduced cushioning to other seat components.

Why Replacement Matters

Renewing a worn insert addresses deterioration in the shoulder padding while retaining the existing seat assembly. Match the part number, size designation and thickness to the required seat configuration.

FAQs

Can the padding be replaced without changing the whole seat?
Individual padding components can be renewed as part of a seat repair, provided the remaining assembly is suitable for continued use.

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

Porsche Motorsport Sitting cushion padding insert for the driver racing bucket seat
Used in Porsche Motorsport track cars to customize the ergonomic fit and seating height for the driver.
• Size / Thickness: Size S / 40 mm
• Application: Porsche Motorsport bucket racing seats

Fits
Porsche 992.1 GT3 CUP 4.0L Model 2021

Diagram ref no 05

What This Product Does

This insert provides padding at the sitting cushion within the driver’s seat assembly. It is an individual seat component, rather than a complete seat or seat shell.

Functions

• Provides cushioning in the seat’s sitting area.
• Allows renewal of the specified padding component during seat refurbishment.

Technical Details

• Manufacturer: Porsche.
• Part number: 9F1881441G.
• Specification: S 40MM.
• Application: MSPORT driver-seat sitting cushion.

Symptoms of Fault

Collapsed seat padding or reduced cushioning can indicate that the sitting cushion needs inspection. Loose rails, adjustment faults and electrical warnings concern other seat components and should not be attributed to this insert without diagnosis.

Why Replacement Matters

Renewing deteriorated cushion padding addresses seating comfort without necessarily replacing the entire seat. Match the existing insert’s specification and part number before selecting a replacement; shoulder, rib, backrest and lumbar padding are separate components within the assembly.

FAQs

• Is this a complete driver seat?
  No. It is the S 40MM sitting cushion padding insert only.
• Can the cushion be renewed separately?
  This insert is listed individually within the driver-seat assembly. Inspect the remaining seat components to establish the work required.
• Does the fitment cover every 992?
  The supplied application identifies the 992.1 GT3 CUP 4.0L 2021–24. Compatibility with other 992 variants is not established.
