Question: Hi. I want to add butterfly doors to my car, but I’m not sure where to begin. Do you know how much butterfly doors cost?
Answer: Butterfly door conversion kits can cost hundreds or even thousands of dollars depending on the make of your vehicle and the type of conversion kit your vehicle requires for installation.
The price of the conversion kit doesn’t include labor costs should you want a professional to complete the installation. This can add as much as $1,500 or more to your total. It also won’t include the cost of having a universal kit modified to fit your vehicle.
Did you know? Butterfly door conversion kits don’t include replacement doors. They come with replacement door bolts and hinges, changing how your existing doors open and close.
Butterfly door options
There are three approaches to getting butterfly doors on your vehicle—DIY, professional installation, and buying a vehicle that already has butterfly doors installed. Each has pros and cons that will affect your final price.
Conversion kit
If you’re a skilled mechanic, you can install the butterfly doors yourself. However, these installations may involve cutting into your fenders and welding various parts to your chassis, so unless you are very experienced, it’s best to have this done professionally.
If you do decide to install a conversion kit yourself, you have the option of buying custom or universal kits. Custom kits cost more, but they’re designed for your specific make and model. Universal kits are cheaper and can be modified to fit most vehicles, but some parts may need to be welded or cut to fit your car.
Professional installation
If you don’t have advanced knowledge about butterfly doors and door installation, have the work done at a professional fabrication shop. This will cost more than doing it yourself, but they’ll be better equipped to handle the modifications that may be needed for a butterfly door conversion.
Built-in butterfly doors
If you love the look of butterfly doors but don’t want the hassle of installing them, consider buying a vehicle that has them pre-installed.
These cars usually cost more than a vehicle with standard doors, but pre-installed butterfly doors are designed to be lightweight, so they’ll be easier to open. You may also avoid some issues that can happen when you convert, like the doors sagging over time.
Some popular vehicles that come with butterfly doors include:
- BMW i8
- Ferrari Enzo
- Ferrari LaFerrari
- Maserati MC20
- McLaren Artura
- McLaren F1
- McLaren P1
- Mercedes-Benz SLR McLaren
- Toyota Cera
Should I get butterfly doors?
Butterfly doors—also known as vertical doors—are a great way to jazz up your vehicle and give it that extra edge. However, they may not be the most practical modification. Opening butterfly doors requires a lot of clearance on either side of your car. That means if other cars park too close, you might not be able to access your vehicle.
Also, even though there are mod kits for most vehicles, it’s not always a seamless transition to butterfly doors. Many doors are too heavy to move up and out easily, so you could find yourself struggling to open your doors. Some butterfly door kits do account for this, adding a shock so it’s easier to lift the door.
There are also safety concerns: If your car ever flips over, it may be difficult to escape if you have butterfly doors installed.
