A Sparco direct fit sub-frame for the Honda Civic EP3. Part number 00499093-1704-EP3.
The EP3 is one of the most commonly seated cars we deal with, and the reason is the standard driving position. Honda put the driver high in that car, and the single most effective thing a bucket seat does in an EP3 is get you down. A direct fit frame is what makes that a bolt in job rather than a fabrication project.
Fitment
Steel frame carrying the 345mm by 271mm base mount pattern. Sparco, OMP and Corbeau base mount seats all use that spacing, so the frame is not limited to Sparco seats whatever older copy on this range said.
Side mount competition buckets do not sit on the frame on their own. They need side mounts or adaption bars in between, which is the usual route in an EP3 because most people fitting one are going to a fixed back shell.
Ordering
Sold singly, one frame per seat, and handed. Choose RHD driver or RHD passenger at the top of the page and order twice if you are doing both sides.
Tell us the seat when you order. Frames in this range are either a complete replacement frame or adaption bars fitted to the existing runners, and that is decided by the car. We confirm which before it ships.
If you are running a harness as well, say so. Seat height in an EP3 changes where the shoulder straps need to anchor, and getting the seat in first and the belts second is the wrong order.
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 made for the Honda Civic EP3 (EP3). 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.
