A Planted Technology seat bracket for the Lexus GS 300, first generation, 1993 to 1997. Part number SB265.
In Japan this car is the Toyota Aristo, which we list separately under SB269. If you have an import rather than a UK GS, send us the chassis number and we will tell you which of the two you need.
The engine is the whole point
The UK and American GS 300 got the naturally aspirated 2JZ-GE. The Japanese Aristo could be had with the twin turbo 2JZ-GTE, which is the Supra engine, and that is why Aristos get imported and GS 300s largely do not.
If you are building one, knowing which engine you have decides a great deal about what the car will do and therefore what seat it deserves.
Giugiaro designed it
Which is why it still looks like nothing else Lexus have made. Original interiors are getting genuinely hard to find, so store what comes out somewhere dry.
Practical
Thirty years old. Get the carpet up and check the metal round the mounting points.
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 Lexus GS 300 [1st Generation] (1993-1997). 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.
