A Planted Technology seat bracket for the Acura TSX, second generation, 2009 to 2014. Part number SB276.
In this country that car is the Honda Accord of the same period, the CU. Acura was Honda’s North American badge and the TSX is the European Accord sold under it, which is why the naming is back to front from a UK point of view.
The first generation TSX takes SB178. Send us the registration and we will confirm.
The V6 and the estate
Two things this generation gained that the first did not: a 3.5 V6 option, and a Sport Wagon. The estate in particular is rare and has a small devoted following.
What the swap gains you
The standard seat is built for a comfortable executive saloon. It is well made and it gives you nothing to brace against, which becomes obvious as soon as the car is driven properly.
If the car covers distance rather than laps, ask us about padded or reclining options instead of a hard shell.
Side airbags throughout. 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 Acura TSX. 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.
