A Sparco direct fit sub-frame for the Porsche 993. Part number 00499112-1725.
On a 993 the original seats are part of the car’s value, and that changes the calculation. A direct fit frame is a reversible installation: the factory seats and their runners come out intact, go into storage, and go back in when the car is sold or shown. Fabricating brackets and putting holes in the floor is not reversible and it will be noticed.
Keep the original fixings with the seats and keep them somewhere dry.
Fitment
Steel, on the 345mm by 271mm base mount pattern, picking up the car’s own floor mounting points. Sparco, OMP and Corbeau base mount seats all share that spacing.
A side mount competition shell needs side mounts or adaption bars over the frame.
Ordering
One frame per seat, handed. Choose RHD driver or RHD passenger and order twice for a pair.
Tell us the seat when you order, and confirm the model year with us. The 911 generations do not share mounting points, and this frame is cut for the 993.
Frames in this range are either complete replacements or adaption bars depending on the car. The photograph is illustrative.
Have you written anything useful for my car?
Yes: Fitting a Recaro Pole Position in a Porsche 993: brackets, rails and room for a tall driver, and Top 5 reclining seat choices for your Porsche 993, 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 Porsche 993 (993). 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.
