A Planted Technology seat bracket for the BMW X1, second generation on the F48 chassis, 2015 onwards. Part number SB278.
The generation that changed drivetrain entirely
This is the important thing to check. The first X1, the E84, is rear wheel drive based on the 3 Series platform. The F48 moved to BMW’s UKL front wheel drive architecture, shared with the Mini and the 2 Series Active Tourer.
They are completely different cars. If yours is a 2010 to 2015 X1, this is not your bracket. Check the chassis code rather than the model name.
What the swap gains you
An X1 is tall and the standard seat is built for comfort rather than cornering. A shell holds you in place and sits you lower, though in a car of this height you will still be higher than in a saloon.
Before anything comes out
Side airbags, occupancy sensing and powered adjustment on higher specifications. Tell us the specification.
Handed, so order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: Lexus Planted Technology Frames Updated For 2026, and Customer Car: Subaru Impreza With Corbeau RRS Seats and Planted Technology Brackets. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is made for the BMW F48. Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, send us the registration and we will confirm before you order.
Which seats does it take?
Check the bolt pattern in the specification against your seat. The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on Planted frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
