An OMP direct fit subframe for the Ford Fiesta Mk5 ST150. Part number HC845-ST150.
ST150, not the standard Mk5
The ST takes its own part within the HC845 family. The standard Mk5 is listed singly and as a pair, and the parts are not interchangeable.
Check the car rather than the badge on the boot, which is the easiest thing on a Fiesta to have been changed.
Why the ST gets seated
It is quick enough that the driver ends up bracing rather than steering. Once you are holding yourself in place with your left leg against the tunnel, that leg is not available for braking, and that is the real cost of a seat that does not hold you.
The ST150 is also a common first competition car, so a good number of these frames go into builds where the seat is the first proper motorsport part the owner buys.
The frame
Steel, base mount, on the mounting points Ford already put in the floor. Nothing is drilled and the standard seats come out whole.
Two bolt patterns, 345mm by 271mm for Sparco, OMP and Corbeau and 405mm by 290mm for Recaro, from multi-hole clusters at each corner.
Sold singly and handed. Order twice for both sides.
Have you written anything useful for my car?
Yes: Top 5 reclining seat choices for your Ford Fiesta Mk6, including our fitting guide, and Top 5 reclining seat choices for your Ford Fiesta ST180, including our fitting guide. 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 Fiesta Mk5 ST150. 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.
