BMW M Carbon Fiber Bucket Seats, Bespoke Leather
CarbonXtreme Global First Release.
Made to Order. Fully Bespoke. One Owner. One Design.
The flagship of the line: a fully custom carbon bucket seat, designed around you and built one to one. Any leather, any quilting, any finish you can envision, on a dry carbon shell.
Not Sure Which BMW M Carbon Bucket Seat Tier Fits You?
- Choose OEM Spec for the factory OEM color palette in OEM Merino leather, at the most accessible price.
- Choose Heritage Fabric for vintage Heritage Pattern fabric centers in houndstooth, tartan and check.
- Choose Bespoke Leather (this page) for a fully bespoke, one-of-one build with a dedicated designer.
A Bespoke Build, Not a Configurator
Bespoke Leather is our highest tier. You are not picking from a dropdown. A dedicated designer works with you one to one, from the first reference to the final stitch, to build a seat that is exactly what you have in mind. Your leather. Your quilting. Your stitching and piping. Your colors and finish. Whatever you can describe, we work to make real. The seats pictured here are real bespoke builds, shown as examples of what is possible, not a fixed menu.
The Listed Price Is a Starting Reference
Because every Bespoke Leather build is unique, the price shown here is a reference for a standard bespoke build. Certain premium hides, rare or exotic leathers, or complex one-of-one design requests may carry an additional cost. If they do, we quote it to you clearly and in writing, and nothing is made until you approve. No surprises, no pressure.
How It Works
- You place your order to begin. This reserves your build slot and starts the conversation.
- Your dedicated designer reaches out to understand exactly what you want, with references, materials, and finishes.
- We confirm the design, the materials, and any additional cost with you in writing before production.
- We build, quality-check, and send you photos for your approval before shipping.
This is how it should be at this level: considered, unhurried, built once and built right.
Fitment and Installation
Confirmed fit for BMW M2, M3, M4, M5 and M8 across G80, G82, G87, F90, G90, F92 and F93, plus F80, F82 and F87. On G-chassis M2, M3 and M4, installation is seamless and direct. On F-chassis cars (F80, F82, F87), the original seat adjustment module and seat control module are removed from your factory seats and carried over to the new seats during installation. Many other shared BMW platforms can also be fitted, including the M SUVs (X3M, X4M, X5M, X6M, XM), the Z4 G29, and the Toyota GR Supra A90. For these and any other model, contact us with your model and year for the specific installation procedure. Installation should be handled by a qualified workshop.
Seat Climate
Every seat is heated as standard. Active ventilation is available as an upgrade (+$800), integrated with the factory comfort-seat ventilation protocol so you control it from your vehicle's infotainment system. For non-M chassis or models without a factory ventilation option, tell us your model and year to confirm availability.
Side Airbags and Shipping
These seats include built-in side airbags, matching factory safety specification.
Shipping options after production:
- Air Freight: $1,450 | Est. 10 to 15 business days
- Sea Freight Express (recommended): $700 | Est. 14 to 22 business days
- Sea Freight Standard: $500 | Est. 33 to 42 business days
Seats ship in wooden crates. Final delivery is truck-based and requires a forklift to offload at the receiving address. To ship straight to your installer, enter the shop address as the shipping address at checkout. Import duties and customs clearance are included in the shipping rate, with no additional fee. Components carrying BMW-branded elements may ship separately, at no additional cost, for compliance reasons.
Made to Order Status
This is a made-to-order, built-to-design commission, processed on a first-ordered, first-built basis. Bespoke builds take a little longer than our standard tiers. Your designer confirms the exact timeline with you before production.
Add Personalized Illuminated Headrest Logo
An illuminated tri-color emblem on the headrest is included. Want your name, initials, or chassis code instead? It is part of the bespoke conversation, or add our Custom Illuminated Headrest Logo Add-On ($449).
Early Launch Pricing
We are in the early launch phase of this build. Current pricing reflects an early-launch offer, and we reserve the right to adjust pricing as we move out of this phase. If we lower the price within 30 days of your purchase, we will refund you the difference.

FAQs
Please read our FAQs page to find out more.
Will these fit my BMW M?
If your model is on our compatibility list and you can share your model and production year plus a few photos of your current seats, the answer is yes. These are confirmed for the BMW M2, M3, M4, M5 and M8 across the G80, G82, G87, F90, G90, F92, F93, F80, F82 and F87 chassis. Many shared BMW platforms also fit, including the M SUVs (X3M, X4M, X5M, X6M, XM), the Z4 G29, and the Toyota GR Supra A90. We confirm fitment with you before production starts — no VIN needed, just your model and year.
Is installation different on G-chassis versus F-chassis?
Yes. On the current G-chassis M2, M3 and M4, installation is seamless and direct. On F-chassis cars (F80, F82, F87), your installer transfers the original seat adjustment module and seat control module from your factory seats to the new seats during installation. For any other BMW platform, send us your model and year and we will give you the specific procedure. Installation should always be handled by a qualified workshop.
Is seat heating included? What about ventilation?
Heating is included as standard on every seat, matching OEM specification. Active Ventilation is an optional upgrade (+$800) — the factory does not offer ventilation on these seats, so we integrate it with the factory comfort-seat protocol, controlled from your vehicle's infotainment system. On non-M chassis or models without a factory ventilation option, tell us your model and year to confirm availability.
Do these seats have side airbags?
Yes. These seats include built-in side airbags, matching factory safety specification. Installation should always be carried out by a qualified workshop, and you should follow your local road and insurance rules.
What is the difference between the three tiers?
OEM Spec is the factory OEM color palette in German-imported OEM Merino leather, at the most accessible price. Heritage Fabric adds custom non-OEM colors, two-tone block designs, and vintage Heritage Pattern fabric centers — you choose a pattern family on that page. Bespoke Leather is a fully bespoke, one-of-one build with a dedicated designer. Compare them here: OEM Spec · Heritage Fabric · Bespoke Leather.
How customizable are the seats, and can I match my interior?
Very. On OEM Spec you choose from the factory color palette in OEM Merino leather, with no color discrepancy against the rest of your factory interior. On Heritage Fabric you choose a pattern family (Houndstooth, Tartan & Check, or Stripe & Weave) along with custom colors and two-tone designs. On Bespoke Leather, a dedicated designer builds a one-of-one specification with you; the listed price is a reference, and certain leathers or design requests may carry an additional cost.
Production, shipping, and what is in the crate?
These are made to order, built on a first-ordered, first-built basis — contact us before ordering for the current timeline. You receive two complete front bucket seats, each supplied as a full replacement assembly with its own structural frame, bottom slider mechanism, and complete seat body. Shipping options after production: Air Freight $1,450 (Est. 10–15 business days), Sea Freight Express $700 (Est. 14–22), or Sea Freight Standard $500 (Est. 33–42). Seats ship in wooden crates; final delivery is truck-based and requires a forklift to offload. To ship straight to your installer, enter the shop address as the shipping address at checkout.
Where does it ship from, duties, and returns?
Import duties and customs clearance are included in your shipping rate, with no additional fee. Components carrying BMW-branded elements may ship separately, at no extra cost, for compliance reasons. As a made-to-order build, orders accept a 30-day cancellation window before production lock; once production begins, orders are non-refundable. We are in the early launch phase — if we lower the price within 30 days of your purchase, we refund you the difference.
