A Planted Technology seat bracket for the Audi A4 and S4 on the B8 chassis, 2008 to 2015. Part number SB098.
We carry the whole A4 run and none of the brackets interchange: B6 is SB097, B7 is SB093, this is SB098 and B9 is SB375. There is also an S4 specific variant under SB098-1.
What changed with the B8
Audi moved the front axle forward, which improved the nose heavy balance the earlier cars were criticised for. The B8 S4 also dropped the V8 for a supercharged V6, lighter over the front axle and considerably more usable.
It is still a heavy four wheel drive car that generates a great deal of grip, and that is what loads you sideways. Nobody fits a shell to a B8 for weight.
Check the seat type
Some A4s of this era split by whether the car has powered or manual seats, because the motors change the floor arrangement. Tell us which you have and we will confirm.
Side airbags and occupancy sensing throughout. 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, and Top 5 reclining seat choices for your Audi A4 B8, including our fitting guide. 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 A4/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.
