To properly install a Cobra Monaco Pro onto an OMP sub-frame, side mounts are essential. Our top recommendations include the Endurance Motorsport Multi-Point M8 Side Mount Brackets for excellent adjustability, the QMS FIA-Approved Steel Side Mounts for a universal fit, and the Endurance Motorsport Steel M8 Side Mounts for a strong, rigid installation. These mounts widen the fitting points, ensuring a secure and safe connection to the OMP sub-frame without modifications.
Can I Install Cobra Monaco Pro Seats onto OMP Motorsport Base Plates?
A customer recently asked us:
“Can I install Cobra Monaco Pro seats onto OMP Motorsport base plates?”
The short answer is no, at least not when using base mounting. While the Cobra Monaco Pro is a popular bucket seat choice, it does not directly fit onto OMP sub-frames due to differences in bolt spacing and mounting points. However, there is a simple and effective solution—using side mounts.
This question came from one of our recent customers who struggled to fit a Cobra Monaco Pro onto an OMP vehicle-specific base frame. The reason? The base mounting points of the Cobra Monaco Pro measure 291mm across, while OMP sub-frames are designed for seats with a 345mm base mounting width. This size difference makes base mounting impossible without modifications, which we do not recommend as it could weaken the integrity of the sub-frame.
The good news is that the Cobra Monaco Pro features both base and side mounting points, allowing you to use side mounts that will align with OMP sub-frames perfectly. Below, we’ll break down the measurements of both products, explain how to install the seat properly and recommend the best side mounts for this setup.
Why Doesn’t the Cobra Monaco Pro Fit OMP Base Plates?
The main issue with installing a Cobra Monaco Pro onto an OMP base plate comes down to bolt spacing differences.
Seat & Sub-Frame Measurement Comparison
- Cobra Monaco Pro Base Mounting Points: 291mm width.
- OMP Sub-Frame Base Mounting Points: 345mm width (at the narrowest mounting points).
Because of this 54mm difference in width, the bolt holes on the seat and sub-frame do not line up, making base mounting impossible without custom fabrication or modifying the frame, which we strongly advise against.
Instead, the correct method is to use side mounts, which widen the mounting points and allow the seat to align with the OMP sub-frame correctly.
How to Properly Fit a Cobra Monaco Pro onto an OMP Sub-Frame
Since base mounting is not an option, the best way to fit the Cobra Monaco Pro onto an OMP sub-frame is by using:
- Side Mounts – These will attach to the side mounting points on the Cobra Monaco Pro, widening the fitting points to match the OMP sub-frame.
- Sparco 345mm-Wide Sliders – Using OMP or Sparco sliders ensures a perfect fitment and allows the seat to move forward and backward for adjustability.
- Adapting the Setup – By combining side mounts, sliders, and the OMP base frame, you get a secure, safe, and fully adjustable seat setup.
By using side mounts, the seat can be securely installed without requiring custom modifications, ensuring proper fitment and maintaining the strength of the sub-frame.

Final Thoughts – How to Properly Fit a Cobra Monaco Pro onto an OMP Sub-Frame
If you’re looking to install a Cobra Monaco Pro seat onto an OMP sub-frame, you cannot base mount it directly due to the different mounting widths. However, by using side mounts, you can ensure a perfect fit without any modifications.
The Correct Installation Method:
- Use side mounts to widen the mounting points.
- Attach the side mounts to the OMP sub-frame.
- Use a Sparco or OMP 345mm-wide slider for adjustability.
This setup ensures a secure, adjustable, and FIA-compliant installation, making it the best solution for track and motorsport use.
