A Planted Technology seat bracket for the Mazdaspeed 3. Part number SB183.
In this country that car is the Mazda 3 MPS. Same car, different badge, and if you have an MPS this is your bracket. Send us the registration and we will confirm it.
Send us the year as well
This listing does not carry one, and Mazda built the MPS across two generations, the BK and the BL, which do not share a floor. We are adding the year data to the listing. In the meantime a registration takes us a minute and saves you ordering the wrong part.
Why the seat matters on this car in particular
The MPS puts a great deal of torque through the front wheels and it is famous for what that does to the steering. A driver who is bracing against the seat with their arms is not steering the car cleanly, and on a car that already fights you under power that costs real time. Being held in place by the seat rather than by the wheel is the whole point.
