A Planted Technology seat bracket for the Lexus SC400. Part number SB160-5029.
The same bracket as our SC 300 and SC 400 listing under SB160, listed separately here so an SC400 owner finds a page naming their car.
SC400 or SC300, and it matters for the build
The SC400 has the 1UZ V8 and was automatic only. The SC300 has the 2JZ-GE and could be had with a manual, which is why the SC300 is the one people convert and the SC400 is the one people keep as a cruiser.
Both are the Toyota Soarer Z30 in Japan. If yours is an imported Soarer, send us the chassis number, because the Japanese cars had specifications never sold here including the turbocharged 2JZ-GTE.
Parts are the practical issue
Good SC and Soarer interior parts are getting genuinely hard to find. The bracket picks up the factory mounting points so the originals come out whole. Store them somewhere dry.
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 car-specific, so match the vehicle in the product name to your exact car and generation. If you are unsure, 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.
