A Planted Technology seat bracket for the Scion xB, 2004 to 2007. Part number SB018.
The first generation, which is the Toyota bB in Japan. The second generation from 2008 is a considerably larger car, so order on the years.
The boxy shape works in your favour
Unusually for a small car, headroom is not the constraint here. The tall roof and upright glass give genuinely good room, and a helmet is not the problem it is in a coupe.
Width between the door card and console is the real limit. Tell us your height and build and we will check what fits.
Why they have a following
They are light, cheap, remarkably practical and completely unlike anything else, which is exactly why people build them. A competition seat in an xB is usually part of a wider build rather than a track requirement, and there is no harm in that.
Because the car is light, ask us about the lighter shells.
Get the carpet up and check the metal, given the age.
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 Scion Xb (2004-2007). 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.
