A PCI Racing adjustable seat mount for the Honda S2000 AP1 and AP2, 1999 to 2010. Part number SM-AP1-A1.
This is the low one. PCI’s adjustable mount gives the largest range of adjustment and the lowest possible seat fitment in their range, and in an S2000 that is the whole argument: the roof is low, most of these have a roll bar behind the driver, and getting under both with a helmet on is the constraint.
What you give up
The slider. The seat is set at installation rather than moving on rails. In a single driver car that costs nothing, and most S2000s built to this level are single driver cars.
It is not permanent either. The hardware interlocks into the slots in the seat base, so the position can be changed later with one tool and without taking the mount out of the car.
If the car is shared, the sliding sub frame is the version to buy instead.
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.
Ordering
Side mount, for a competition bucket, bolting to the factory seat mounting points so nothing is drilled. Handed, order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: The 2026 Honda S2000 - A modern Revival Of An Iconic Roadster, and What Fibreglass Bucket Seats Fit In A Honda S2000?. 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 Honda S2000 AP1, Honda S2000 AP2. 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.
