What actually fits and what to expect before you start
Upgrading the seats in a Ferrari 348 for track or race use is very different from fitting seats to most modern performance cars. The 348 was never designed with aftermarket racing seats in mind, and there are no true bolt-in solutions available. Every successful installation follows the same pattern: narrow fixed-back seats, very low mounting, and some level of bespoke fabrication.
This guide explains what has been proven to work in real Ferrari 348 track builds, why the car is so restrictive, and what customers should realistically expect before committing to a seat upgrade.
Why the Ferrari 348 is difficult for seat fitment
The 348 cockpit combines several challenges that stack against easy seat installation. The cabin is narrow, the transmission tunnel is wide, and the roofline is low. On top of that, the factory seat rails and bases are tall, placing the original seats high in the car.
Once the OEM seats are removed, it becomes clear that the original mounting system does not translate to universal aftermarket frames. There are no manufacturer-approved subframes available from Sparco, OMP, Recaro, Cobra, or other major brands. Every documented track or race build involves removing the factory rails entirely and starting again.
As a result, seat fitment in a Ferrari 348 is not a plug-and-play exercise. It is a packaging problem that must be solved with the right seat choice and the correct installation approach.
Starting With The installation Methods And Techniques
What type of seats can realistically be used
Only fixed-back racing seats are viable for track or race use in the Ferrari 348. Reclining seats are generally unsuitable due to their width, height, and the additional bulk of the reclining mechanism. In practice, they interfere with the transmission tunnel, door cards, or roofline long before a usable driving position is achieved.
Seats that have been successfully fitted in modified Ferrari 348 builds are all narrow-shell competition seats. Examples documented in real-world builds include older narrow Sparco shells such as the Pro 2000, compact versions of the Sparco Sprint, and earlier OMP competition seats. These seats share the same key traits: controlled external width, relatively thin base cushions, and compatibility with side mounting.
Modern wide shells, XL sizes, and large halo-style seats generally do not fit without significant modification. In the 348, shell width is often the limiting factor rather than padding or upholstery.
Why the OEM seat rails are not reused
In almost every Ferrari 348 track or race build, the factory seat rails are removed completely. Retaining them nearly always results in the seat sitting too high, especially once a helmet is worn.
The original rails add unnecessary height and are incompatible with side-mounted racing seats. For this reason, race builds prioritise mounting the seat as low as physically possible, often directly to the floor structure using custom solutions.
This approach mirrors what Ferrari themselves did with the 348 Challenge cars, which used fixed-back OMP seats mounted directly to the chassis with bespoke brackets rather than adapting the road car hardware.

Seat Types That Work Best In The RS200
How seats are actually mounted in a Ferrari 348
Because there are no direct-fit frames, Ferrari 348 racing seats are mounted using fabricated solutions. Common approaches include welded or bolted steel crossbars, custom aluminium or steel side plates, or direct floor mounting with reinforced spreader plates.
The seat itself is typically mounted using FIA-approved steel side mounts, which are then attached to the custom floor solution. Sliding rails are rarely used. When they are, they tend to be heavily modified low-profile versions, and clearance remains extremely tight.
This type of installation work is normal for race-prepared 348s and should be expected rather than avoided
Seat position, angle, and clearance
To achieve a workable driving position, seats in the Ferrari 348 are usually mounted very low and with a noticeable rearward recline. It is common for the shell to sit between floor pressings rather than on top of them to gain precious millimetres of headroom.
Clearance around the transmission tunnel and door cards is one of the biggest constraints. Inner bolsters often contact the tunnel, while outer shoulders can foul the door trim. Solutions seen on track builds include slight seat offset towards the door, replacing door cards with flatter panels, or minor trimming of seat shell bolsters on race-only cars.
These modifications are standard practice in competition builds and are not considered unusual in this chassis.

Seat belts and harness considerations
The factory seat belts in a Ferrari 348 are mounted to the original seats rather than the floor. Once those seats are removed, alternative belt mounting solutions are required.
Common approaches include floor-mounted anchors using reinforced points, harness bars, roll cage crossbars, or eye-bolt anchors in the rear bulkhead. Many track cars retain the original three-point belts for road use and add clip-in harnesses for circuit driving.
All belt and harness mounting must be properly reinforced and installed to motorsport standards for safety.
Ferrari 348 Challenge cars as a reference point
Ferrari 348 Challenge cars provide the best factory reference for correct race seat installation in this chassis. These cars ran fixed-back OMP racing seats mounted directly to the floor with bespoke brackets. There was no attempt to retain road car hardware or provide adjustability beyond what was necessary.
Modern track builds follow the same philosophy. Narrow FIA-approved seats, mounted low, with purpose-built brackets, are the proven approach.
What this means for customers
There is no guaranteed bolt-in racing seat solution for the Ferrari 348. Any installation will require a narrow fixed-back FIA-approved seat, removal of the OEM rails, and bespoke mounting work carried out by a professional race fabricator or motorsport workshop.
Because installation methods vary and tolerances are tight, seat fitment cannot be guaranteed without physical measurement and test fitting. This is not a flaw in the products, but a reality of the chassis.
Our recommendation
For Ferrari 348 track or race builds, the approach is clear. Choose narrow fixed-back FIA seats only. Expect bespoke installation work. Involve a professional motorsport workshop, and always test-fit before final mounting.
We are happy to advise on shell dimensions, seat suitability, and known successful options based on real-world builds. To do this accurately, we will always ask for driver height and build, intended use, and whether a roll cage or harness bar is fitted. This allows us to give realistic advice and avoid false expectations from the outset.
