A Planted Technology seat bracket for the BMW M240i. Part number SB120-M240i.
The SB120 design runs across a wide span of BMWs, starting with the E92 3 Series coupe and carrying through the F22, the M2 and the F80 M3, because BMW kept the same seat mounting arrangement. We list it separately against each car so owners find a page naming theirs.
Why an M240i gets built
It is the sensible person’s M2: the same B58 straight six family, rear wheel drive, a short wheelbase, and considerably cheaper. A great many owners conclude they have most of what the M car offers for a fraction of the money, and then spend the difference on tyres and track days.
The seat is where it shows
The standard sports seat is better than average and it still lets you move once the car is loaded up. In a short car that rotates readily, feeling that early is the whole game.
Side airbags, occupancy sensing and usually powered adjustment. Tell us the specification.
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 car-specific, so match the vehicle in the product name to your exact car and generation. If you are unsure, 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.
