The Seat Ibiza Mk3, in its 6L chassis form (2002 to 2008), is the generation that includes the Cupra sport variant, which has become a popular track day and motorsport platform. OMP’s HC814 subframe is the vehicle-specific frame for the 6L floor mounting points. It is the correct frame for this generation, not for the earlier Mk2 or the later Mk4 (6J), which have different floor geometries.
Steel construction, powder-coated black. The HC814 drops into the factory floor mounting points in place of the standard seat runners, without drilling. Both bolt patterns are supported: 345mm x 271mm for OMP and Sparco base-mount seats, and 405mm x 290mm for Recaro. That covers the four main seat brands without needing a different subframe for each: Corbeau, OMP, Recaro, and Sparco base-mount seats are all compatible.
Sold as a single. For driver and passenger seats, order two. Available in RHD driver side and RHD passenger side.
Before ordering, confirm which seat you are fitting so we can check the correct bracket between the subframe and the seat. The bracket varies by seat model, and sorting that upfront avoids a second order. No bolts supplied beyond the standard floor hardware already in the car.
Have you written anything about this exact product?
Yes, we have covered this exact product: Customer Car: BMW E39 With Bucket Seats Fitted Using Planted Technology Subframes, and Seat Ibiza MK3 6L with Corbeau seats. 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 Seat Ibiza Mk3 6L. 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) and 405mm x 290mm (the Recaro seat pattern). 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 OMP 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.
