Planted Technology seat brackets for the Audi S4 on the B8 chassis. Part number SB098-1.
We list this alongside the A4 and S4 B8 listing under SB098, so that an S4 owner searching for an S4 bracket finds a page naming their car. Send us the registration and we will confirm exactly what your car needs before you order.
What the B8 S4 is
Audi dropped the V8 for this generation and fitted a supercharged 3.0 V6, which is lighter over the front axle and considerably more usable than the engine it replaced. It also gained the optional sport differential, which genuinely changes how the car behaves on the exit of a corner.
Why the seat matters here
It is heavy and it generates a great deal of grip. Nobody fits a shell to a B8 S4 for weight, because it will not register on the scales. What changes is that you stop moving about when the car is loaded up, which happens sooner than the comfortable interior suggests.
Before anything comes out
Side airbags, occupancy sensing and powered adjustment, with memory on higher specifications. 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 Audi S4 B8. 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.
