A Planted Technology seat bracket for the Mazda 3, third generation. Part number SB264.
The BM and BN cars, 2013 to 2018. We list three Mazda 3 brackets and none interchange: SB260, this one, and SB404 for the fourth generation. Send us the registration and we will name the part.
What changed with this generation
Mazda’s Skyactiv work, which took real weight out of the car and sharpened the chassis considerably. This is the generation where the 3 became genuinely good to drive rather than merely competent, and it is why they turn up at track days.
There is no MPS version of this generation. Mazda dropped the turbocharged model after the previous one, so if you are looking for a Mazdaspeed 3, that is an earlier car.
What the swap gains you
The standard seat is comfortable and offers very little laterally, which shows up quickly once you use the chassis properly.
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.
