A Planted Technology seat bracket for the Subaru WRX, second generation on the VB chassis, 2022 onwards. Part number SB401.
The current WRX, and one of the newest cars Planted make a bracket for. The previous VA generation takes SB206.
What is different about the VB
It sits on the Subaru Global Platform with a bigger 2.4 turbo flat four, and for the first time in a long while there is no STI version. Subaru have said the model is not returning in this generation, which makes the standard WRX the only one there is.
That matters practically: there is no factory bucket seat option to consider keeping, as there was on previous STIs. The standard seat is what you have.
Why a WRX gets seated
On loose surfaces the car moves under you constantly and the standard seat lets you move with it. Once a harness goes in that becomes the limiting factor, because the harness holds you to a seat that is itself shifting.
Side airbags, occupancy sensing and powered adjustment on higher specifications. Tell us the specification.
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 Subaru WRX. 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.
