A Planted Technology seat bracket for the Subaru WRX and STI from 2015, and the XV Crosstrek fourth generation 2013 to 2017. Part number SB206.
Two quite different vehicles on one base part number, which follows from Subaru’s platform sharing. There is also an XV Crosstrek specific version under SB206-4935, so if you have the crossover rather than the WRX, check that listing too and send us the registration.
The VA WRX
This is the generation where the WRX finally stopped being an Impreza. Subaru split the model line, gave the WRX its own body and put the FA20 turbo in it, while the STI kept the older EJ257.
That matters when you are ordering: a 2015 WRX and a 2015 STI have different engines but the same floor, so both take this bracket.
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.
Side airbags and occupancy sensing throughout. Handed, so order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: Top 5 reclining seat choices for your Subaru Impreza WRX/STI, including our fitting guide, and Lexus Planted Technology Frames Updated For 2026. 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/STI (2015+) / XV Crosstrek [4th Generation] (2013-2017). 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.
