An OMP direct fit subframe for the Ford Escort Cosworth. Part number HC778.
A Group A homologation special, built in small numbers, and worth a great deal of money. That should shape how you approach the whole job.
Reversible is the only sensible route
This frame bolts to the factory mounting points, so the original seats come out whole, go into storage and go back in when the car is sold. Nothing is cut and nothing is welded. On a car of this value and provenance, a floor that has been drilled is a permanent mark against it.
Store the original seats and every one of their fixings somewhere dry and label them.
If it is a competition car
Plenty of Escort Cosworths are still competing, and historic and rally class rules can be specific about seats and mounting. Tell us the class before you order anything and we will check the seat as well as the frame.
What else you need
Side mounts and the seat. Seat choice stays open. The 345mm by 271mm spacing covers Sparco, OMP and Corbeau base mount seats, and the frame also carries the 405mm by 290mm Recaro pattern, which a Sparco frame does not. Cobra use 291mm by 330mm and need multi hole side mounts.
Order twice for a pair. Talk to us first on this one.
Have you written anything useful for my car?
Yes: Custom Cages Ford Escort Roll Cages, and Pair of Corbeau PSR Sports Recliners Transform Our Customer's Ford Escort Mk1. 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 Ford Escort Cosworth. 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.
