Why XC3 Engineering Bucket Seat Bases Are the Smart Choice for BMW Enthusiasts
When you're pushing your car to the limit—on track or fast road—driver position is everything. Confidence in your seat translates directly to confidence behind the wheel. That’s where XC3 Engineering’s Bucket Seat Bases come in.
Crafted with precision in the UK and engineered for BMW chassis compatibility, these bases offer a rigid, bolt-in solution for securely mounting aftermarket racing seats such as Recaro, Sparco, Bride, and Cobra.
🔧 Built to Fit. Built to Last.
XC3 seat bases are not universal; they're purpose-built for BMW platforms, ensuring a perfect fit without compromise. Whether you're installing them in an F80 M3, E92 M3, or a track-prepped M2, you'll benefit from a base that mounts directly to the factory seat bolts with zero cutting, welding, or guesswork.
Key Features:
-
CNC Machined – Strong, precise, and built for hard use
-
Black Anodised finish – Durable and corrosion-resistant

XC3 bases are sold individually to suit driver or passenger side, giving you flexibility depending on your build stage. Whether you're going full race car or just want a more planted feel during spirited drives, these bases offer a clean, professional-grade foundation.
And yes—XC3 bases are compatible with sliders if you prefer adjustable seating.
