Customer Question: Can I Fit a Cobra Bucket Seat In My Honda Del Sol?

This is a question we’ve heard many times from customers looking to upgrade the seating in their Honda Del Sol. With its compact size and unique targa-top design, the Del Sol is one of those cars that really benefits from a more supportive and sporty seat, especially if you’ve upgraded suspension or plan to take it on track. But before you go picking any fixed-back bucket seat, you need to know what actually fits.

The interior space in the Del Sol is tight. There’s limited room between the door cards and the center console, which makes it a challenge for fitting wide seats with large shoulder wings. That’s why we focus on recommending seat models we’ve already seen successfully installed into this chassis—specifically the Cobra Monaco Sport and Cobra Monaco Pro.

In this blog, we’ll walk through everything you need to know before buying a bucket seat for your Del Sol. We’ll cover the seat width limits, what to expect from the Monaco seat range, and why 560mm is the maximum shoulder width we recommend without doing any interior modifications. You’ll also get a look at fitting options and alternative seat models that fit within the same size range. Whether you’re after FIA approval, daily usability, or just want a seat that holds you tighter through corners, this guide will give you a clear direction forward.

Cabin Space in the Honda Del Sol

The Del Sol’s cabin is narrow, with limited width between the door cards and center console. There’s just enough room for slim fixed-back seats, which means you’ll need to avoid any model with oversized shoulder supports or wide bolsters. These kinds of seats can either sit against the door trim or prevent proper adjustment, making driving uncomfortable or even unsafe.

Because of this, it’s important to stick to seats with shoulder widths under 560mm, which we’ve found is the tipping point for getting a bucket seat to fit without needing to modify the car. Anything wider than that and you’ll likely have to start altering door panels or shifting the center console to get clearance.

The Biggest Cobra Seats That Fit: Cobra Monaco Sport and Pro

When working with the tight interior of the Honda Del Sol, you’re limited in terms of how much shoulder width you can run without interfering with the door cards. Through past installs and customer setups, we’ve found that the Cobra Monaco Sport and Cobra Monaco Pro offer the best balance between width, support, and fitment.

The Cobra Monaco Sport measures 520mm at the shoulder, and in the car we’ve pictured above, you can clearly see how tight the clearance is between the seat’s upper side supports and the inner door trim. Even though it’s a snug fit, the seat drops in cleanly and still allows for proper belt access and seat positioning.

That minimal leftover space is what makes the Cobra Monaco Pro the maximum width we’d recommend. It shares the same basic shape as the Sport but is slightly wider at the shoulder, coming in at 560mm. While 40mm might not sound like a huge jump, it takes the Monaco Pro right up to the usable space limit inside the Del Sol. It fits, but anything wider than this, especially seats with extended shoulder wings, will likely press against the door or require trimming of interior panels.

The benefit of using the Monaco Pro as your upper limit is that it gives you a solid benchmark. Any seat equal to or narrower than the Pro will fit without needing to alter your car, giving you more flexibility when choosing seat alternatives. It’s also FIA-approved, making it ideal if you’re looking to use the car for competitive driving while keeping the install straightforward.

If you’re building a clean, well-supported interior without hacking into trim or modifying the shell, the Monaco Sport and Pro are the seats to base your setup on. They’re comfortable, proven to fit, and work with the mounting hardware we offer for the Del Sol.

Cobra Monaco Sport and Pro: What Makes Them Great

Both the Monaco Sport and Monaco Pro are built on a high-strength steel frame, which gives them a solid and reliable structure that’s well suited for both road and motorsport use. Unlike lightweight composite shells that can feel rigid or unforgiving for daily driving, the steel-frame design offers a good balance of strength and durability with just enough compliance to make longer journeys comfortable. It also makes these seats incredibly tough under load, which is a key factor for drivers who need something dependable on track days or under hard braking and cornering forces.

Their deep bucketed shape is what gives these seats their signature feel. With high side bolsters running along the hips and lower back, the seat wraps around you and keeps you firmly in place when turning into corners or hitting curbs. This kind of lateral support is especially useful in cars like the Honda Del Sol, where the factory seats offer very little body control during aggressive driving. The upper section of the seat includes pronounced shoulder wings and a sculpted backrest that keeps your torso supported without feeling cramped.

Both seats also feature integrated harness slots in the shoulders, hips, and crotch area, making them compatible with 4-, 5-, or 6-point racing harnesses. This makes the Monaco range a practical upgrade for drivers looking to fit a proper harness setup while maintaining comfort and structural safety. Whether you’re securing yourself with a factory belt for road use or going all-in with FIA-spec harnesses, the Monaco Sport and Pro are both designed to accommodate either layout without compromise.

The Monaco Pro is fully FIA 8855-1999 approved, making it suitable for competition use, while the Sport offers the same profile in a slightly lighter spec. They both feature a compact and upright shape that works well in smaller cars.

Key features include:

  • Steel-framed design for strength
  • High side bolsters for lateral support
  • Harness slots for 4-, 5-, or 6-point belts
  • Slim shoulder profile (520mm for Sport, 560mm for Pro)
  • Compact base and backrest for tight interiors

Monaco Pro Seat Dimensions: Your Fitment Reference

Monaco Pro Seat Dimensions: Your Fitment Reference

If you’re looking for a reference point on what fits in the Honda Del Sol, the Cobra Monaco Pro is it. Here’s a quick look at the main external dimensions:

  • Shoulder width: 560mm
  • Base width (outer): 510mm
  • Overall height: 870mm
  • Overall depth: 660mm
  • Leg support height: 180mm

With its compact shell, this is the largest seat you can run in the Del Sol’s cabin without needing to start modifying door cards or other interior trim. It’s snug, but it fits.

The Cobra Monaco Collection

We stock a wide range of Cobra Monaco seats in different trim levels and configurations. These include:

  • 3D Spacer Fabric for improved breathability
  • Velour and vinyl finishes, depending on your preference
  • Houndstooth editions for a classic look
  • Custom options with logos, coloured stitching, and more

Every listing details whether it’s built on the Monaco Sport or Monaco Pro shell, so it’s easy to find a version that suits your build. The only seat from this family we do not recommend for the Del Sol is the Monaco Sport GT, which has wider shoulders that exceed the 560mm fitment limit.

Fitting the Seat: Use the Right Sub-frame

To get the Cobra Monaco seats securely into your Honda Del Sol, we recommend using our Planted Technology vehicle-specific sub-frame. This frame is designed to bolt straight into the factory seat mounting points in the Del Sol’s floor, meaning no cutting or welding is needed. It provides a solid base and includes all the common bolt hole patterns used across the aftermarket seat industry, including the 291mm bolt pattern found on all Cobra bucket seats.

One of the great things about the Cobra Monaco seat range is that they can be fitted using either side mounts or base mounts, giving you some flexibility with how you set them up. If you use side mounts, you’ll have the ability to adjust the tilt angle of the seat, ideal if you want to fine-tune your driving position or set a more upright posture for better visibility. On the other hand, base mounting the seat directly to the sub-frame will place the seat as low as possible in the cabin, which is useful if headroom is a concern or you want a race-style seating position.

Whichever option you choose, the Planted frame is compatible with both setups and works perfectly with our universal side mount brackets and optional sliding runners. This gives you a simple, secure, and adjustable install that suits daily driving or weekend track use, all without having to modify the car’s interior.

Final Thoughts: Getting the Right Fit in the Del Sol

If you’re looking to upgrade the seats in your Honda Del Sol, you’ll want to choose something compact, supportive, and easy to install. Based on real-world experience and size testing, the Cobra Monaco Pro is the largest bucket seat that will fit without modification. It’s comfortable, motorsport-ready, and works seamlessly with our vehicle-specific mounting frame.

Keep in mind that anything wider than 560mm at the shoulders is going to be a challenge, so always check dimensions before you buy. Whether you’re going for the Monaco Pro, Sport, or a similarly sized alternative, there are great options available that’ll keep you planted behind the wheel.
