A Planted Technology seat bracket for the Toyota Supra, 1993 to 1998. Part number SB023.
The A80, the Mk4. The Mk3 takes SB129 and the current car takes SB367.
Values decide everything about this job
A80 prices have gone somewhere genuinely absurd, and a manual twin turbo is in another bracket again. Original interiors are a large part of what a good one is worth, and a car with a drilled or cut floor tells a story it does not need.
This bracket picks up the factory mounting points so nothing is cut. Store the original seats and every fixing somewhere dry and label them. That sounds obvious and people still lose the bolts.
If it is a track car
Plenty of A80s are, and there is no shame in it. The standard seat was built for a grand tourer and the car generates far more grip than it was designed around, particularly once the 2JZ has been worked on.
Tell us what the car is for and we will suggest something that suits.
Handed, so order twice for a pair.
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 Supra. 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.
Is this bracket held in stock, or made to order?
Made to order rather than shelf stock, so budget 3 to 5 weeks from ordering to dispatch.
