A Planted Technology seat bracket for the Honda S2000 on the AP1 chassis. Part number SB046.
The AP1 ran to 2003 and revved to 9,000rpm with the 2.0 F20C. The later AP2 takes SB107, and Honda dropped the limit slightly with the 2.2 engine while making the car considerably easier to drive quickly.
The AP1 is the one that bites
Early cars have a reputation for snap oversteer, and Honda revised the suspension in response. Whatever you make of the fairness of that, the practical point stands: an AP1 asks you to notice what the back axle is doing early and act on it.
You cannot do that while bracing yourself against a seat that is moving. On this car more than most, that is the honest case for a shell.
Getting the position right matters here
Honda got the standard driving position unusually right, so a badly chosen mount can make an S2000 worse. Tell us your height and be specific about what you want to change.
Roof down, so ask us about trims that shed water. Side airbags fitted.
Have you written anything about this exact product?
Yes, we have covered this exact product: Lexus Planted Technology Frames Updated For 2026, and Customer Car: Subaru Impreza With Corbeau RRS Seats and Planted Technology Brackets. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is car-specific, so match the vehicle in the product name to your exact car and generation. If you are unsure, 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 Planted frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
