Planted Technology seat brackets for the Porsche 997. Part number SB017-4957.
Planted’s own SB017 listing covers the 996, Boxster, 997, Cayman and 991 together, because Porsche kept a common seat mounting arrangement across the water cooled cars. We break that out per model so a 997 owner has a 997 page to find. Same bracket.
The 997 in two halves
Gen 1 cars to 2008 have the M96 and M97 engines. Gen 2 from 2009 brought direct injection and a different engine architecture, and reputations and values differ sharply between them. If you are buying or building one, that distinction matters more than almost anything else about the car.
The GT cars
997 GT3, GT3 RS and GT2 came with factory bucket seats that are worth serious money in their own right. If yours has them, tell us what you are trying to achieve before you spend anything.
Practical
Airbags, occupancy sensing and powered adjustment on most. Tell us the specification and we will work through it.
Have you written anything useful for my car?
Yes: Top 5 reclining seat choices for your Porsche 997, including our fitting guide, and Lexus Planted Technology Frames Updated For 2026. Those are written around the same car, from real fittings and customer questions, so they are worth a look before you decide.
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.
