A Planted Technology seat bracket for the Nissan 200SX on the B14 chassis, 1995 to 1998. Part number SB345.
Read this before you order, because the name is a trap
In this country, 200SX means the S13 or S14 Silvia: rear wheel drive, turbocharged, the drift car. The B14 is not that car. It is the North American 200SX, which is a front wheel drive Sentra coupe, and the two have nothing in common beyond three characters.
If you have a UK 200SX, this is the wrong bracket. Send us the registration and we will point you at the right one. We would rather sort that now than have you unbolt a seat and discover it.
What the B14 actually is
The SE-R version is the one worth building, with the SR20DE engine, and it is a light, cheap, well balanced little thing with a following in club events. It is closely related to the B13 Sentra, which takes SB384.
Practical notes
Light car, so a heavy steel framed shell gives back a real slice of what makes it quick. Ask us about lighter options, and check the metal round the mounting points with the carpet up 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 Nissan 200SX. 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.
