A Planted Technology seat bracket for the Audi A6 and S6 on the C4 chassis, 1994 to 1997. Part number SB111.
There is also a second C4 listing under SB111-1. Send us the registration and we will tell you which of the two your car takes.
The name changed, the car did not
Audi renamed the 100 as the A6 in 1994 without changing the car underneath. So a 1993 Audi 100 and a 1994 A6 are effectively the same vehicle, and the C4 S4 from 1991 became the C4 S6 in 1994 with no meaningful change.
If you are researching what others have fitted, search on Audi 100 as well. There is considerably more information under the older name.
The S6 Plus
Rare, V8 powered, Audi’s own motorsport division built them, and the estate version is one of the great sleepers. If yours is one, tell us, because originality is worth real money on those.
Practical
Thirty years old. Get the carpet up and check the metal before you spend.
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 [C4 Chassis] (1994-1997). 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.
