A PCI Racing adjustable seat mount for the Porsche 911, 1999. Part number SM-911-A1.
The low option. PCI’s adjustable mount gives the largest range of adjustment and the lowest possible seat fitment in their range, at the cost of the seat no longer moving on rails.
In a 911 that trade usually makes sense for a track car and less sense for a road car. You already sit fairly low, but a competition seat on a slider adds height back, and if you have a cage or a harness bar in you will feel it with a helmet on.
Not a one time setting
The hardware interlocks into the slots in the seat base, so the position can be changed later with one tool without taking the mount out of the car. If you change seats in two years you are not starting again.
If the car is shared, the sliding sub frame is the version to buy.
Construction
Laser cut and CNC formed from one piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, five and six point sub belt mounting locations built in.
Before you order
Confirm the generation with us. The year on this listing is the fitment, and 911 generations do not share mounting points.
Side mount, handed, order twice for a pair. Keep the factory seats, they are worth money.
Have you written anything useful for my car?
Yes: Top 5 reclining seat choices for your classic Porsche 911, including our fitting guide, and 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. 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 PCI frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Base mount or side mount, and does it matter?
This is a side-mount frame: the seat hangs between side brackets bolted through its flanks, the motorsport-style stack that gives fine height and angle control. Our guide on base mount versus side mount explains the whole fitting stack.
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.
