A Planted Technology seat bracket for the Subaru BRZ and Toyota GR86, second generation, 2021 onwards. Part number SB392.
One bracket for both, because they are the same car built in the same factory. The first generation takes the SB161 family.
What the second generation fixed
The 2.4 engine. The first car’s 2.0 had a well known flat spot in the mid range that the 2.4 largely removes, and the body is meaningfully stiffer. It is a better car in the ways owners of the first one complained about.
What has not changed is the philosophy: modest grip, light weight, and a car that rewards being smooth rather than brave.
Which is exactly why the seat matters
You cannot be smooth while holding yourself in place with your arms. On a car whose entire appeal is precision at modest speeds, a seat that moves under you costs more than it would in something faster.
Headroom is tight with a helmet on, so tell us your height. Side airbags throughout.
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 Toyota GR86. 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.
