A Sparco direct fit sub-frame for the Peugeot 405. Part number 00499050-1718.
A sub-frame is what makes a seat swap a bolt in job. It picks up on the floor mounting points Peugeot already put in the car and gives the new seat a flat 345mm by 271mm base to sit on, so nothing is drilled and the seat load goes into structure designed to carry it.
Fitment
Base mount seats on the 345mm by 271mm pattern, which covers Sparco, OMP and Corbeau base mount shells. The old same brand only claim across this range was not right.
Side mount competition buckets need side mounts or adaption bars fitted above the frame.
Ordering
One frame per seat, handed. Choose RHD driver or RHD passenger and order twice for the pair.
Tell us the seat when you order. Frames in this range differ car by car between complete replacements and adaption bars, and the photograph is illustrative rather than a picture of the 405 part.
On a 405 the floor is the thing to check before you spend anything. Lift the carpet, look at the metal around the mounting points, and if it is soft, deal with that first. A frame can only feed load into sound structure.
Will this fit my car?
This frame is made for the Peugeot 405. 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.
