A Planted Technology seat bracket for the Audi A6 and S6 on the C7 chassis, 2011 to 2018. Part number SB348.
C7 is the chassis code and it is what to order on. The A7, S7 and RS7 of the same period share this platform but take SB342, so they are separate parts despite the relationship.
The C7 S6 is a V8
Twin turbocharged 4.0, with cylinder deactivation, in a large saloon or estate that weighs close to two tonnes. The RS6 Avant built on this platform is one of the fastest estates ever sold and is the reason most people know the generation.
What you are actually buying
Not weight saving. In a car this heavy a steel framed shell will not register on the scales, and it is worth being clear about that.
What changes is that you stop moving about, and in a two tonne car generating this much grip you move about more than the plush interior lets on.
The electronics
Powered adjustment in several planes, memory, heating, ventilation on some, side airbags and occupancy sensing. Tell us the specification before you order anything.
Have you written anything about this exact product?
Yes, we have covered this exact product: Top 5 reclining seat choices for your Audi A6 (97 Onwards), including our fitting guide, and Lexus Planted Technology Frames Updated For 2026. 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 A6/S6. 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.
