A Planted Technology seat bracket for the Mercedes SLK, 1996 to 2004. Part number SB117.
The R170, and the car that popularised the folding metal roof on an affordable two seater.
Which is the practical constraint
The roof folds into the boot, and the mechanism takes up a great deal of room behind the seats. That limits how far back a seat can travel and how much you can recline into, more than it would in a soft top.
Tell us your height and the seat you are considering and we will check it clears everything before you order, because this is a car where a shell that fits on paper can foul the mechanism in practice.

The R170 floorpan is what the Chrysler Crossfire was built on, which is worth knowing if you are hunting for parts.
The AMG
The SLK32 AMG with the supercharged V6 is the version worth building, and it is rare.
Side airbags are fitted. 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 Mercedes SLK. 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.
