A Planted Technology seat bracket for the BMW F80 M3. Part number SB120-F80 M3.
The SB120 design covers a wide span of BMWs, starting with the E92 3 Series coupe and carrying through the F22, the M2 and the M240i, because BMW kept the same seat mounting arrangement across them.
We list it separately against each of those cars so that an M3 owner searching for an M3 bracket finds one. Same part, listed where people will look for it.
What the F80 needs
It is the first turbocharged M3 and it makes its torque low down, which makes it easier to unstick than the naturally aspirated cars before it. Feeling that early is the difference between catching it and not, and you cannot feel it through a seat you are sliding around in.
The carbon buckets
Optional from the factory, excellent, and worth real money. If yours has them, tell us what you are trying to solve first, because there are owners who would do better keeping them.
Side airbags and occupancy sensing. 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 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.
