A Planted Technology seat bracket for the Porsche 996, Boxster, 997, Cayman and 991, 1998 onwards. Part number SB017.
This is the base part for the modern water cooled Porsches
Five model lines across two decades on one design, which follows from Porsche keeping a common seat mounting arrangement through the water cooled era. Suffixed versions cover the 997 under SB017-4957, the 991 under SB017-4958 and a second 991 under SB017-4960-1.
Four listings on one family. Send us the registration or the model year and we will name the part, because working that out from the titles is not reasonable.
The Boxster and Cayman are worth calling out
They are mid engined and the 911s are rear engined, and they still share this mounting arrangement. If you have a 987 Cayman S or a Boxster Spyder, this family is where you are looking.
The GT cars
996 GT3, 997 GT3 and the RS versions came with factory bucket seats worth serious money. Tell us before you spend.
Airbags and occupancy sensing throughout. Tell us the specification.
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 Porsche 996 / Boxster / 997 / Cayman / 991 (1998+). 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.
