These sub-frames are the fitting hardware for the Ford Fiesta ST180, the 1.6-litre turbocharged ST variant produced from 2013 to 2018. SKU 00499109-ST180.
The ST180 has different floor mounting points from the standard Mk6 and Mk7 Fiesta. Using the standard Fiesta sub-frames in an ST180 will not give correct alignment, which is why this variant exists as a separate product.
Bolt pattern is 345mm x 271mm. Compatible with Sparco, OMP, and Corbeau base-mount reclining and bucket seats. These frames are the correct floor hardware for the ST180 regardless of which of those three seat brands you are fitting.
The frames are handed, so driver side and passenger side are different. Choose the side at time of order. For a full two-seat build, order twice. At £77.50 per frame, a full interior swap comes to £155.
Steel construction. The frames fix directly to the ST180’s OE floor mounting points with no drilling required for the frame fixings.
Have you written anything about this exact product?
Yes, we have covered this exact product: Top 5 reclining seat choices for your Ford Fiesta ST180, 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 Ford Fiesta ST180. 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.
