The Sparco sub-frame for the BMW 1-Series (part 00499080) is a vehicle-specific fitting frame for 1-Series models from 2005 to 2011. It bolts to the standard floor mounting points in place of the original seat runners and provides the 345mm x 271mm base mount bolt pattern used across the Sparco, Corbeau, and OMP base mount seat ranges.
These frames are universally sided, meaning one part covers both driver and passenger positions in a right-hand-drive car. Sparco’s sliding runner kit is recommended if fore-aft seat adjustment is needed. Without runners, the seat position is fixed. Construction is steel. Sold individually.
One point to note on the part code: 00499080 is the BMW 1-Series application. If you have seen variant codes with a dX or SX suffix, those suffixes refer to the Honda Integra fitment, not the 1-Series. The 1-Series frame is 00499080 without a suffix.
At £75.50, this sub-frame is in the lower half of the price range for Sparco’s car-specific fitting hardware. Because the 345mm x 271mm bolt pattern is shared with Corbeau and OMP base mount seats, these frames give access to a wider choice of sport seats than their Sparco branding suggests.
Have you written anything about this exact product?
Yes, we have covered this exact product: Top 5 reclining seat choices for your BMW 1-Series, 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 BMW 1-Series. 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.
