Direct fit subframes for the Porsche 911 991, locating on the factory seat mounts, so nothing is cut. Part number SU-PO-CA-1.
This is the Cayman frame
The 991 shares its floor mounting arrangement with the Cayman, so the same frame fits. We list it separately under the 991 with a suffixed code, because that is the car people look for and very few would think to search for a Cayman part.
It is the same physical frame, not an adaptation. If you have been told there is no direct fit frame for a 991, this is the answer.
Think about position before you think about the seat
The frame replaces the standard runners and picks up the floor points already in the car. It sets your seat height and how far back you sit, and in a 911 the standard driving position is already good, so any change to it should be deliberate rather than incidental.
If you are chasing helmet clearance, the frame does most of that work. If you are chasing lateral support, the seat does. Tell us which it is and we will point you at the right end of the problem.
The runner is included
Cobra supply the sliding runner with the frame at no extra cost, unlike Sparco, Planted, OMP, Recaro and Corbeau.
Built around the Cobra seat range. Base mount at 291mm x 330mm. Priced per frame, which fits one seat.
Have you written anything useful for my car?
Yes: Top 5 reclining seat choices for your Porsche 911 991, including our fitting guide. Those are written around the same car, from real fittings and customer questions, so they are worth a look before you decide.
Will this fit my car?
This frame is made for the Porsche 911 991. 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?
Cobra design each tailored frame around a particular seat, so check the Compatible seats tab above for the designed pairing. Other seats with a matching bolt pattern can work as cross-compatible components rather than a designed set, so ask us before mixing brands.
Do I keep fore-and-aft adjustment?
Yes, and unlike most brands the sliding runner comes included with a Cobra frame, in the price. That changes the like-for-like comparison against other makers, where the runner is a separate part on top. Our guide to sliding runners covers how they work.
Base mount or side mount, and does it matter?
This is a base-mount frame: the seat bolts down through its base, the simpler stack that suits seats with a flat bottom and keeps the install low-fuss. Our guide on base mount versus side mount explains the whole fitting stack.
