A Planted Technology seat bracket for the Toyota Celica All-Trac GT-Four, 1990 to 1993. Part number SB253.
The ST185. All-Trac is the North American name and GT-Four is the one used elsewhere, and it is the same car.
A homologation special with a complicated history
Toyota won the World Rally Championship with this car, and then were excluded from the sport for a year in 1995 over an illegal turbo restrictor on the ST205 that followed it. The ST185 is the honest champion and it is the one collectors want.
Values reflect that. Originality counts, so the bracket picks up the factory mounting points and nothing is cut. Store the original seats and every fixing somewhere dry and label them.
If you are competing
Historic class rules are frequently specific about seats and mounting. Tell us the class before you order anything and we will check the seat as well as the bracket.
The non four wheel drive Celica of the previous generation takes SB191. Check which you have.
Have you written anything about this exact product?
Yes, we have covered this exact product: The Best Bucket Seats and Sports Recliners for the Toyota Celica GT4, 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 Toyota Celica All-Trac GT-Four (1990-1993). 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.
