A Planted Technology seat bracket for the Audi 4000, 1980 to 1987. Part number SB185.
In this country that car is the Audi 80 of the B2 generation. Same car, different name for the North American market.
The connection worth knowing
The B2 platform is what the Ur-Quattro was built on, and the 4000 quattro shares a great deal with it including the four wheel drive system. That is why a modest looking eighties saloon has more of a following than the badge suggests, and why parts knowledge crosses over.
If you have a B2 Audi 80, 90 or Coupe, send us the registration and we will confirm the fitment.
Practical
The bracket picks up the factory mounting points so nothing is cut, which matters as these become collectable in their own right.
Forty year old Audi floors deserve a proper look with the carpet up before you spend anything.
A period trimmed shell suits a car of this age better than a modern carbon bucket. Handed, so order twice for a pair.
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 4000. 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.
