These sub-frames are the fitting hardware for installing a base-mount sport seat into a Honda Civic EK. SKU 00499092 at £72.50.
The EK is the sixth-generation Honda Civic three-door, produced from September 1991 to March 2001. If your car is a different generation (EG before 1991, or EP3 from 2001 onwards), the mounting points differ and you would need the sub-frame for that generation.
The frames are handed, so choose driver side or passenger side at time of order. Two orders for a full two-seat build.
Bolt pattern is 345mm x 271mm. Compatible with Sparco, OMP, and Corbeau base-mount seats on that pattern. All three brands work with these frames.
Fore-and-aft adjustment requires the Sparco sliding runners, available separately. Without them, seat position is fixed at the sub-frame height. The runners raise the seat slightly, which is worth checking against your headroom before adding them.
Have you written anything about this exact product?
Yes, we have covered this exact product: Budget Bucket Seats For A Honda Civic EK: What Fits, And What It Costs. 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 Civic EK. 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?
It takes seats drilled 345mm x 271mm (the Sparco and OMP seat pattern). 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 Sparco 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 base-mount frame: the seat bolts down through its base, the simpler stack that suits seats with a flat bottom and keeps the install low-fuss. 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.
