Ford Mustang 1999 Fitment Guide With Cobra Monaco Pro Seats
At GSM Performance, we love seeing how our customers modify their cars using our range of racing seats and accessories. Recently, a customer visited our showroom to pick up a set of Cobra Monaco Pro steel-frame fixed-back racing seats for their 1999 Ford Mustang GT. They had a unique goal for their installation—fitting aftermarket bucket seats while retaining the factory electric seat controls. This would allow them to adjust the seat position with ease, combining the comfort of the original setup with the enhanced support and security of a motorsport seat.
After completing the installation, they shared their experience with us, providing details on the modifications required, the products used, and how well the setup worked. The result was a racing bucket seat that provided a much-improved driving position while keeping the electric adjustments fully functional. By adapting the factory seat frame with side mounts, they achieved a secure fit without losing the ability to fine-tune the seat position, something that’s not always possible with fixed-back bucket seats.
This guide will go through the details of their setup, covering the fitment process, the adjustments they made, and the specific products that made it all possible. If you’re considering a similar upgrade for your Mustang or any other performance car, this installation example provides valuable insights into how to achieve a high-performance seat fitment while maintaining everyday usability.
Customer’s Seat Setup & Fitment Inside the Mustang
Our customer wanted to install a racing seat while retaining the factory electric seat controls, allowing for smooth forward and backward adjustments. This would ensure comfort and practicality for both road and track driving.
Installation Process
- The factory seat cushions were removed by undoing the four bolts securing them to the original seat frame.
- Some modifications were needed to the frame, including grinding back two notches to allow the Endurance Motorsport side mounts to align with existing mounting points.
- The side mounts were then bolted onto the frame, providing the attachment points for the Cobra Monaco Pro seat.
- With the seat sitting higher due to the raised side mounts, the lowest setting was required. However, the seat’s shape caused interference, so the top half of the side mounts had to be trimmed to clear the plastic trim for the lap belts.
- Once installed, the factory electric seat controls were tucked behind the driver’s seat, remaining accessible for adjustments.
After a week of testing, the customer confirmed that the seat was securely installed and working perfectly. The frame was later removed for painting to protect it from rust.
