Complete fitting kit: side mounts included. These frames come with their own side mounts, so any side mount bucket seat bolts straight to them. You only need the seat and the frame, with no separate side mounts to buy.
This listing is for a matched pair of M2 Motorsport direct fit sub-frames for the Honda S2000 AP1, one driver-side and one passenger-side in a single purchase. Part number M2-20274-S000, the same frame as the individual listing, bought together for a full interior seat swap.
The AP1 S2000 (1999 to 2003, F20C 2.0-litre 9000rpm roadster) is a narrow-cockpit car that benefits considerably from a lower, more centred seating position. The pair listing also covers the AP2 (2003 to 2009), which uses the same floor mounting.
For full specification and vehicle-specific notes, see: M2 Honda S2000 AP1 Direct Fit Sub-frames.
Steel, black powder coat, 290mm side mount holes. Compatible seats: Recaro, OMP, Sparco, Bride, Corbeau, Cobra, Takata, MOMO and others. Choose fixing type at checkout.

Will this fit my car?
This frame is made for the Honda S2000 AP1. 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 M2 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.
