The Volkswagen Golf Mk4 (1998 to 2004) remains a popular track car, particularly the 1.8T and V6 variants, and OMP’s HC780-Golf-Mk4 subframe fits its floor without modification. The Mk4 shares a platform with the Audi A3 8P, but the seat mounting points differ between the two, so the A3 frame is not interchangeable with this one.
Steel construction, powder-coated black. Drops into the factory floor mounting points. Both bolt patterns supported: 345mm x 271mm for OMP and Sparco-sized seats, 405mm x 290mm for Recaro-spaced seats. 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.
When ordering separately from a seat, tell us which seat you are fitting so we can confirm the bracket between the frame and the seat. No bolts supplied.
Have you written anything about this exact product?
Yes, we have covered this exact product: Top 5 reclining seat choices for your Volkswagen Golf Mk6, including our fitting guide, and Top 5 reclining seat choices for your Volkswagen Golf Mk5, including our fitting guide. 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 Volkswagen Golf Mk4. 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.
