A Planted Technology seat bracket for the BMW 6 Series on the E24 chassis, 1976 to 1989. Part number SB091.
Thirteen years on one bracket, which tells you how little BMW changed the seat mounting across the run. The modern F13 6 Series takes SB390.
The M635CSi
BMW put the M1’s straight six into the E24 and produced one of the best looking fast cars of the eighties. Values have gone a long way and originality counts, particularly on the M cars.
The early E24s to 1982 are built on the E12 5 Series floorpan; later cars moved to the E28. Worth knowing when you are hunting parts, and worth sending us the registration if yours sits near that changeover.
Which decides the approach
The bracket picks up the factory mounting points so nothing is cut. E24 sports seats are worth money on their own and are getting genuinely hard to find, so store them and label the fixings.
Practical
E24s rust round the floors, the arches and the screen surround. Get the carpet up and look properly before you spend.
A period trimmed shell suits an E24 far better than a modern carbon bucket.
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 E24. 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.
