A Planted Technology seat bracket for the Nissan Sentra, third generation on the B13 chassis, 1990 to 1994. Part number SB384.
We list the Sentra across four generations and none interchange: this, 2000 to 2006 under SB082, 2007 to 2011 under SB106 and the B17 under SB411.
The SE-R is the one with the reputation
SR20DE, a limited slip differential, around 1,100kg, and a chassis that flattered the driver. American motoring press of the day compared it to a BMW 2002 and meant it. That is why a thirty five year old economy saloon still has a following.
Nissan sold closely related cars here under the Sunny name. If that is what you have, send us the registration and we will check rather than assume from the badge.
Weight is the argument
It is light, and a heavy steel framed shell gives back a real slice of that. Ask us about the lighter options.
Get the carpet up and check the metal round the mounting points, 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 Sentra. 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.
