A Planted Technology seat bracket for the Honda Civic Si, 2002 to 2005. Part number SB043.
The Si of these years is the EP3, which in this country and in Japan is the Civic Type R.
Three cars, one shell, very different specifications
The American Si is the mildest. The UK Type R got a higher output K20 and, crucially, the Japanese JDM Type R got a different again engine, a limited slip differential as standard and a helical gearset. If yours is an import, send us the chassis number rather than the registration.
The Recaros
UK Type R cars came with Recaro seats and they are worth real money as prices on good EP3s climb. Store them and their fixings properly if they come out, and label them.
Note also that a factory Recaro will not bolt to standard side mounts.
The gearstick
Worth mentioning on an EP3: the dashboard mounted shifter means the centre console area is unusual, and it changes what clearance you have beside the seat. Tell us your build and we will check.
Have you written anything useful for my car?
Yes: Budget Bucket Seats For A Honda Civic EK: What Fits, And What It Costs, and Lexus Planted Technology Frames Updated For 2026. 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 Honda Civic SI (2002-2005). 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 Planted 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.
