How to Fit Sparco and Corbeau Reclining Seats into an M2 Motorsport Frame
Upgrading your car’s seating with Sparco or Corbeau reclining sports seats is a great way to enhance comfort, support, and driving position. However, ensuring a secure and low-mounted fitment can be challenging, especially when using aftermarket frames.
At GSM Performance, we highly recommend using M2 Motorsport fitting frames for installing Sparco and Corbeau recliners. These frames are vehicle-specific, providing the lowest possible seating position while making installation straightforward and secure.
In this guide, we’ll break down:
✔ Why M2 Motorsport frames are ideal for aftermarket seats
✔ How the M2 Motorsport frameworks
✔ How to fit Sparco and Corbeau reclining seats using adapter plates
✔ Potential fitment issues and solutions
Why Use M2 Motorsport Fitting Frames for Reclining Seats?
The M2 Motorsport frame is one of the best solutions for mounting aftermarket reclining or fixed-back seats because it is:
- Vehicle-Specific – Designed for a range of cars including Honda Civic, Nissan GTR, Mitsubishi Evo, VW Golf, and Toyota models, ensuring proper fitment.
- Super Low Fitment – Offers one of the lowest possible seating positions, perfect for taller drivers needing extra headroom.
- Pre-Drilled for Easy Install – Features factory-matching bolt points, making installation quick and secure.
Unlike universal frames, the M2 Motorsport frames fit directly to your car’s floor pan, aligning with factory bolt points for a stable and secure mounting solution.
How the M2 Motorsport Frame Works
The M2 Motorsport fitting frame is a 3-in-1 mounting system that provides:
- A vehicle-specific base frame that bolts directly into the factory floor mounting points.
- Pre-installed sliding runners for easy forward and backward seat adjustment.
- Side mount bolt points for installing fixed-back bucket seats without additional brackets.
For side-mounted bucket seats, installation is straightforward as the side mounts bolt directly onto the frame. However, for base-mounted reclining seats like Sparco and Corbeau recliners, an adapter plate is required to align the seat’s narrower bolt pattern with the wider M2 frame base.
Adapting M2 Motorsport Frames for Base-Mounted Recliners
Since M2 Motorsport frames are designed primarily for side-mount seats, their base width is too wide for direct installation of recliners. To resolve this, adapter plates are used to:
- Attach to the M2 sliding runners
- Provide correct bolt spacing for Sparco and Corbeau reclining seats (345mm wide bolt pattern)
- Ensure a strong and flush fitment
Without these adapter plates, the bolt holes will not align properly, making secure installation difficult.
How to Fit Sparco Reclining Seats onto an M2 Motorsport Frame
Sparco reclining sports seats, such as the Sparco R100, are compatible with M2 Motorsport frames using the adapter plate method.
How to Fit Corbeau Reclining Seats onto an M2 Motorsport Frame
Corbeau reclining seats, such as the Corbeau SVR, also use the 345mm bolt pattern required for M2 Motorsport frames. However, fitment is slightly more complicated due to the larger reclining mechanism on the side of the seat.
Potential Fitment Issues & Solutions
🔹 Seat belt mounting points may interfere with the Corbeau reclining mechanism.
🔹 To fix this, use the 291mm forward bolt pattern on the Corbeau seat to move the seat further back, creating clearance.
🔹 If seat belt mounts still cause interference, removing the mount from the frame may be necessary (this does not affect safety).
Recommended M2 Motorsport Frames & Accessories
When fitting Sparco or Corbeau reclining sports seats onto an M2 Motorsport frame, the M2 Motorsport Adaption Brackets are an essential component. These brackets solve the bolt pattern mismatch, allowing reclining seats to be securely and safely installed.
Why Use M2 Motorsport Adaption Brackets?
- Designed for Reclining Seats – Aligns with the 345mm bolt pattern of Sparco and Corbeau recliners.
- Strong & Secure Fitment – Ensures stable mounting onto M2 Motorsport frames.
- Versatile Compatibility – Works with multiple M2 Motorsport seat frames for different vehicle models.
- Easy Installation – Simply bolt onto the sliding runners, providing a flush mounting point.
Without these brackets, Sparco and Corbeau recliners cannot be directly mounted to an M2 Motorsport frame due to bolt spacing issues. By using these adaptation brackets, you ensure proper seat alignment, safety, and adjustability for an optimal driving position.
