A Planted Technology seat bracket for the Mazdaspeed 6, 2006 to 2008. Part number SB327.
In this country that car is the Mazda 6 MPS. Same car, different badge. If you have an MPS, send us the registration and we will confirm.
Four wheel drive changes the argument
Unlike the Mazdaspeed 3, which sends everything through the front wheels and is famous for what that does to the steering, the 6 puts its 2.3 turbo through all four. That means it puts the power down cleanly and carries far more speed through a corner.
Which is precisely why the seat matters here. The torque steer problem is gone, so what limits you is grip, and high grip is what loads you sideways in the seat. A standard 6 seat is a saloon seat.
Rarity
Mazda built relatively few and they were never sold in large numbers here. Interior parts are getting hard to find, so keep the originals whole and store them somewhere dry.
Side airbags are fitted. 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 made for the Mazdaspeed 6 (1st Generation). 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.
