A Planted Technology seat bracket for the BMW 1 Series, 2008 to 2011. Part number SB139.
The E82 and E88, which is the generation with the straight six and rear wheel drive, and the reason people care: the 135i, and beyond it the 1M. Small, quick, and driving the correct wheels.
The related part numbers
This is the base of the SB139 family. The M140i takes SB139-1, which is the later F20 generation. Different car, related design, and worth sending us the registration to separate them.
We also list an OMP subframe for the E87 hatchback, which is the same generation in a different body.
What the car needs
A 135i is short, stiff and rotates quickly, and the standard seat lets you move about while that is happening. The 1M came with better bolstered seats and they are worth real money now, so if yours is a 1M, tell us before you order anything.
Practical
A 1 Series is not large inside and the tunnel is substantial. Tell us your height and build.
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: Top 5 reclining seat choices for your BMW 1-Series, including our fitting guide. 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 1 Series. 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.
