Porsche OEM 911 991 982 981 Carbon Fiber & Alcantara LWB Bucket Seats L+R
OEM Porsche Full Lightweight Bucket Seats (LWBs)—often referred to as the “918-style” seats—are the pinnacle of factory Porsche interior equipment. Found in the 991 GT3/RS, 911R, GT2RS, and the 718 (982) GT4/Spyder, they are a direct “plug-and-play” upgrade for the 981 and 991 generations.
Key Specifications (991 / 982 / 981)
Unlike the earlier folding versions, these are fixed-back shells designed for maximum rigidity and weight savings.
-
Construction: Full Carbon Fiber Reinforced Plastic (CFRP) with a visible gloss carbon weave on the rear.
-
Weight: Approximately 12kg (26 lbs) per seat.
-
Materials: Black Leather bolsters with Alcantara (Race-Tex) centers and embroidered headrest logos (GT3, GT4, Spyder, or Crest).
-
Adjustability: Electric height adjustment (up/down) via a toggle switch on the side; manual fore/aft adjustment.
Fitment & Installation Compatibility
These seats use the same rail dimensions across the 991, 981, and 718 (982) platforms.
| Model Series | Compatibility Note |
| 911 (991.1 / 991.2) | Direct fit for Carrera, Turbo, and GT models. |
| 718 / 981 (Boxster/Cayman) | Direct fit; highly popular for GTS and “S” models. |
| 992 / 718 GT4 RS | While they look identical, 992-generation seats use different airbag sensors and wiring pins. Ensure these are the 991/982 specific versions. |
Value Drivers for Inventory & Sales
If you are managing these for a client or listing them for your shop, these specific details significantly impact the market price (which often exceeds $15,000–$20,000 for a pristine pair):
-
Airbags & Occupancy Sensors: Genuine OEM units include integrated thorax airbags and the passenger-side weight sensor (PODS). This is the biggest advantage over aftermarket seats—no “Airbag Failure” lights.
-
Harness Ready: Pre-drilled for 6-point harnesses (Schroth or Porsche Motorsport).
-
Stitching Color: Most common is Platinum Grey or Guards Red. Custom “PTS” stitching (e.g., Acid Green or Shark Blue) carries a significant premium.
-
Seat Inserts: The Alcantara centers are Velcro-attached and can be easily swapped for “Pepita” (houndstooth) or Tartan fabrics for a classic look.
Professional Documentation Tip
When inspecting these L+R sets, check the outer bolsters carefully. Because they are deep and fixed-back, they often suffer from “entry/exit wear.” If the leather is pristine or has bolster protectors installed, the resale value is maximized.
