SKU 00499044 is the steel base-mount sub-frame for the Vauxhall Corsa C, covering the December 2000 to 2005 production run. It bolts into the Corsa C’s floor mounting points in place of the standard seat runners and accepts any base-mount sport seat using the 345mm x 271mm bolt pattern from Sparco, OMP, or Corbeau.
One detail specific to this application: the Corsa C sub-frame requires Sparco sliding runners as part of the installation. Unlike some sub-frames that position the seat directly, this setup uses the runners between the frame and the seat to complete the mounting. The runners are SKU 0049306 for a single or SS0049302-X2 for a pair. Factor them into the build budget alongside the sub-frame.
Both driver and passenger sided versions are listed for RHD cars. This listing covers one sub-frame.
Corsa Cs appear regularly in Rallycross, autocross, and entry-level circuit racing, and they are a common choice for road-to-track builds where the owner wants a sport seat without committing to a full cage installation. The base-mount approach suits this use: the build remains reversible and the car can be returned to standard without permanent modification.
At £75.50 for the sub-frame, plus runners if needed, this is a straightforward fitment for a popular small track car.
Will this fit my car?
This frame is made for the Vauxhall Corsa C. 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.
