A Planted Technology seat bracket for the Audi A5 and S5, second generation, 2016 onwards. Part number SB347.
Built on the B9 platform alongside the A4 of the same period, which takes SB375. The first generation A5 and S5 takes SB166.
What the second generation S5 changed
Audi dropped the supercharged V6 for a turbocharged one, which moved the power delivery lower down and made the car feel considerably stronger in the mid range. It also lost some of the linearity the supercharged car had, which owners of both will argue about at length.
The RS5
Twin turbo V6, four wheel drive, and quick enough that the standard seat is the limitation on track. Audi offered better bolstered seats on the RS, so tell us what yours has before you spend.
Plan the electronics
Side airbags, occupancy sensing and powered adjustment, with memory on higher specifications. Taking a seat out without dealing with that lights up the dashboard. Tell us the specification before you order.
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 Audi A5 S5. 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.
