A Planted Technology seat bracket for the Acura NSX, 1991 to 2005. Part number SB003.
In this country that car is the Honda NSX.
The first mass produced all aluminium monocoque
Which is the thing to understand before anyone goes near the floor with a drill. Honda built the NSX with an aluminium structure, and aluminium does not behave like steel when you cut, weld or load it in ways it was not designed for.
This bracket picks up the factory mounting points so nothing is cut. On this car that is not a preference, it is the only responsible approach.
Think twice before changing the seats at all
Values have gone somewhere serious and originality counts heavily. Ayrton Senna was involved in developing the chassis, the driving position was obsessed over, and the standard seats are part of what the car is.
Tell us what the car is for before you spend. If it is a road car, we may well tell you to leave it alone. If it is a track build or a class with a seat rule, that is a different conversation and we will work it through properly.
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 Acura NSX. 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.
