A pair of PCI Racing sliding sub frames for the Honda S2000 AP1 and AP2, 1999 to 2010. Part number SM-AP1-S1-X2.
Both sides in one order, handed for driver and passenger.
Wide or narrow
This is the wide version. PCI make these mounts in a wide and a narrow, and which you need depends on the seat rather than the car: a broader shell needs the wide mount to sit square, a narrow competition bucket sits better on the narrow version.
Tell us the seats you are fitting and we will confirm before anything ships. This is the most common mistake on S2000 mounts and it takes two minutes to avoid.
The slider
The seats move fore and aft after installation. PCI’s S1 slider bolts to the base with four bolts where a conventional slider uses two, which they rate as twice as strong as two bolt mounting.
If you want the lowest possible fitment, the adjustable mount sits lower. In an S2000, with the roof and usually a roll bar to clear with a helmet on, that is worth weighing up.
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.
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. 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.
