XC3 Bucket Seat Floor Mount Adapter - BMW M2 G87 M3 G80 M4 G82
Achieve the perfect low-slung, race-ready driving position in your vehicle with the XC3 Engineering Bucket Seat Floor Mount Adapter. The standard factory seats in the G8X platform are heavy, bulky, and sit too high for optimal circuit track use—especially when wearing a helmet. This premium floor mount adapter provides an ultra-low, structurally reinforced foundation that bolts directly to the factory chassis floor tracks.
Precision CNC-machined in the UK from premium 6082-T6 billet aluminum, these adapters offer vastly superior tensile strength and rigidity compared to lower-grade steel or flexible universal rails. Finished in a sleek black anodized coating with a laser-engraved logo, the adapter tracks adjust to handle side-mount seat widths from 365mm to 405mm, lowering your center of gravity and unlocking maximum chassis feedback.

FAQ
Q: Is this product sold as a full car set or individually per seat?
A: These billet floor mount adapters are priced and sold individually per side (Driver Side or Passenger Side). If you intend to swap out both front factory seats for track buckets, you must select and add both the driver and passenger side kits to your cart.
Q: Can I mount my original factory seat belt receptacle to this bracket?
A: Because the factory seat belt buckle is physically attached to the moving OEM seat frame, you will need to pair this adapter with our optional XC3 Seat Belt Mounting Bracket to securely retain your road-legal 3-point seat belt or secure lap-belt harness provisions.
Q: Does this fit both manual and electronic factory car chassis floors?
A: Yes. The underlying floor pan footprint and bolt dimensions remain identical across all G8X models regardless of whether the stock seats were manual or fully electronic, allowing this adapter to bolt down flawlessly.
