A Planted Technology seat bracket for the Subaru Impreza, fifth generation on the GK and GT chassis, 2017 to 2023. Part number SB416.
By this point the Impreza and the WRX are separate cars
Which is the thing to check. Subaru split the model lines properly, and the fifth generation Impreza is a naturally aspirated family car on the Subaru Global Platform. The WRX of the same period is a different vehicle.
If yours is turbocharged, this is very likely not your bracket. Send us the registration and we will point you at the right one.
What the SGP gave it
A considerably stiffer shell than the outgoing car, which is genuinely noticeable and is why these handle better than the modest power suggests. It is a decent chassis with a sensible engine on top.
Why people fit shells
Club events where four wheel drive and low running costs matter more than power, or a high mileage car with a tired seat. Those want different things, so tell us which.
Side airbags and occupancy sensing throughout. Tell us the specification.
Have you written anything useful for my car?
Yes: Top 5 reclining seat choices for your Subaru Impreza WRX/STI, including our fitting guide, and Lexus Planted Technology Frames Updated For 2026. Those are written around the same car, from real fittings and customer questions, so they are worth a look before you decide.
Will this fit my car?
This frame is made for the Subaru Impreza 5th 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.
