A Planted Technology seat bracket for the Nissan 300ZX on the Z31 chassis. Part number SB152-2.
Our title says 300Z and it should read 300ZX. We are correcting that.
We list the Z31 twice, this and SB152. Either page gets you a Z31 bracket, and we will confirm against your chassis number if you want certainty. The Z32 from 1990 is a different car and takes SB051.
The Z31 is the forgotten Z
It sits between the classic S30 cars and the Z32 that everybody wanted, and for years it was the one nobody bothered saving. The turbocharged 300ZX Turbo and the rare Shiro Special are the versions with a following.
That neglect is why survivors are scarce and why prices have started to move.
Practical
Forty year old Z floors deserve a proper look with the carpet up before you spend anything.
A period trimmed shell suits a Z31 better than a modern carbon bucket. Ask us.
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.
