The BMW G87 M2 has quickly established itself as one of the most driver-focused modern M cars, and with that has come a growing demand for purposeful, weight-conscious interior solutions that match the performance of the chassis.
The release of the Karbonius G87 M2 Carbon Rear Seat Delete Closeout Kit answers that demand with a system engineered specifically for enthusiasts who want more than a cosmetic change. This is a complete interior transformation that removes unnecessary bulk, reduces rear cabin weight, and replaces the factory rear seat with a precision-fit carbon structure that looks native to the platform.
Now available through IND, this is the first dedicated carbon closeout system for the G87 developed with true OEM-level fitment and motorsport functionality in mind.
Why the Rear Seat Delete Makes Sense on the G87 M2
The G87’s compact dimensions, wide track, and S58 powerband make it uniquely responsive to weight reduction and distribution changes.
Removing the rear seat provides measurable and real-world advantages:
- Reduced overall vehicle mass
- Improved rear weight balance
- Sharper transitional response
- Increased usable storage for track equipment
For customers who regularly attend HPDE events, time attack sessions, or canyon drives, the rear seat is rarely used but always carried. Replacing it with a structural closeout turns unused space into a functional extension of the car’s performance focus.
Just as importantly, it changes the visual identity of the interior. The rear cabin becomes an extension of the driver’s environment rather than a passenger compartment.
Engineering and Construction
Karbonius manufactures each G87 closeout in Spain using Italian-sourced pre-preg carbon fiber, a process chosen for its strength, consistency, and extremely low weight.
Every kit is:
- Factory serialized
- Production dated
- Built with exacting tolerances
The system consists of a complete 4-piece panel architecture designed to install using OEM mounting points with no permanent chassis modification.
Key construction features:
- Pre-preg 2x2 3K carbon fiber
- V-pattern weave for a symmetrical motorsport aesthetic
- UV-stable clear coat for long-term durability
- Fully reversible installation
The result is a structure that integrates into the vehicle as if it were designed as a factory CSL-style option.
Functional Gains Beyond Weight Reduction
While weight savings are the headline benefit, the usability improvements are equally significant.
The closeout system:
- Creates a dedicated storage area for helmets, tools, and track gear
- Prevents cargo movement under hard driving
- Improves cabin organization for track use
- Reinforces the driver-focused layout of the G87
For dual-purpose street and track cars, this turns the rear interior into a functional performance space rather than unused volume.
Developed From Proven G8X Experience
Karbonius’ work on the G8X platform did not begin with the G87.
The success of the G82 M4 carbon rear seat delete system established the foundation for:
- Panel alignment and mounting strategy
- Long-term durability
- OEM-quality fitment standards
That experience carries directly into the G87 version, resulting in a more refined and better integrated solution from the outset.

With our finishing touches
First IND Development Car Appearance – Bimmer Invasion Florida
As a brand-new release for the platform, this product will make its first appearance on an IND development vehicle at Bimmer Invasion Florida this April.
Link to our G87 M2 build: https://ind-distribution.com/blogs/news/the-race-to-auratium-building-ind-s-g87-m2-in-four-weeks
Our G87 M2 will feature a custom-configured version of the Karbonius closeout, demonstrating how the production system can be integrated into a fully developed chassis.
The focus of this release remains the product itself, its engineering, its fitment, and the transformation it delivers for G87 owners.
The IND vehicle serves as a real-world example of how the system can be executed at the highest level.
The custom configuration will be revealed publicly for the first time at the show.
OEM Integration With Motorsport Intent
One of the defining characteristics of Karbonius components is their ability to deliver race-inspired function without compromising factory-level refinement.
In the G87, that balance is critical.
The closeout:
- Follows the factory interior geometry
- Maintains proper panel transitions
- Installs using original mounting locations
- Can be returned to stock if desired
This allows customers to build a more focused car without permanently altering the chassis.
Now Available at IND
The Karbonius G87 M2 Carbon Rear Seat Delete Closeout Kit is now available through IND.
For customers attending Bimmer Invasion Florida, this will be the first opportunity to see the system installed in a fully developed G87 build.
For everyone else, this release marks the next step in transforming the G87 M2 into a more focused, purpose-built driver’s car.
