Corbeau direct-fit sub-frames for the Honda Civic EJ9, built from 1996 to 2000. Part code HONDACIVICEJ9.
The EJ9 is the base-specification 6th-generation Civic, and it is a favourite platform for lightweight club motorsport and autocross. Kerb weight in some configurations is around 1005kg, and the wide availability of VTEC engine swaps and a strong aftermarket make it a practical starting point for a dedicated track car. Many EJ9 builds are going in that direction rather than remaining road conversions, and a proper seat is a core part of that setup.
These sub-frames are specific to the EJ9 floor geometry. They bolt to the original floor mounting points without modification. Corbeau-seat-specific bolt pattern. Both driver and passenger positions covered.
Price is for one sub-frame set. Seat is not included.
Have you written anything useful for my car?
Yes: Budget Bucket Seats For A Honda Civic EK: What Fits, And What It Costs, and Honda Civic FK8 Type R with Sparco Evo XL & TRS Red Harnesses. 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 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 Corbeau frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
