Are you a car enthusiast looking to upgrade your ride? Consider the Mustang Coupe to Fastback conversion. Both are timeless American muscle cars known for their iconic design. One is not better than the other. So why consider a conversion?
There are a couple of reasons. If you have a rusted-out coupe that would need a total overhaul, then it’s the perfect candidate to convert to a fastback. If you’re going to spend the money and time to get your coupe rust-free and road-ready, you might as well convert it to a Fastback, if that’s something you’d prefer.
Also, if you’ve been wanting a Fastback but the original Fastback prices are out of your range, then a Coupe to Fastback conversion is an awesome option for you!
Keep reading if you’re trying to decide if a classic Ford Mustang Coupe to Fastback conversion is the right choice for you.
Costs and Technical Details

Ah, the iconic Ford Mustang. When you think of classic American muscle cars, the Mustang is probably one of the first names that comes to mind. But did you know that you can convert a Mustang coupe into a Fastback? Yes, you read that right. And if you’re wondering whether it’s worth considering, read on.
Let’s talk about the costs and technical details. While cheaper than purchasing an original Mustang fastback, this is not necessarily a cheap project. The average cost of a conversion can range from $8,000 to $20,000+. This includes everything from labor costs to parts and materials. The process itself can take anywhere from a few weeks to a few months, depending on the complexity of the customizations you want. And you’ll need some decent technical expertise to pull off the conversion. This can be a DIY job (I’ve done it myself multiple times), but the work is not for everyone and may require outside labor.
But here’s the thing: if you’re willing to shell out the cash and hire the right people to get the job done, the results can be incredible. The transformed car will look sleeker, sportier, and sexier than ever before. It’s a whole new level of aesthetics and design that will turn heads every time you hit the road. And let’s not forget that a fastback conversion can significantly increase the resale value of your Mustang. It’s a smart investment in the long run.
Now, if you’re thinking about performance upgrades, you’ll want to have even more cash set aside. This can happen over time, but if you’re driving a fastback, you’ll probably want an engine and transmission to match the aggressive exterior, plus all the other performance upgrades needed to get your converted fastback safely on the road.
There are some potential drawbacks to consider as well. The costs are no joke, and you’ll need to have a good amount of savings or financing to make this happen. It’s also not a quick job, so if you’re in a rush to get back on the road, keep that in mind. And finally, there may be some technological obstacles to overcome, depending on the age and condition of your Mustang.
All things considered, though, a fastback conversion is definitely worth considering if you’re a true Mustang enthusiast. It’s a unique and exciting way to take your love of classic American muscle cars to the next level. So why not give it a shot? We promise you won’t regret it.
Aesthetics and Design

When it comes to aesthetics and design, the classic Ford Mustang fastback is iconic. The sweeping roofline and sloping rear end give it a bold and aggressive appearance. The limited production of the Mustang fastback means that they are sought after by collectors and enthusiasts alike. Converting a Mustang coupe to a Fastback is a popular way to get the same stunning look but at a lower price.
Customization options are endless with a coupe to fastback conversion. You have the ability to fully customize the exterior and interior of your Mustang, making it a true one-of-a-kind. You can choose from a variety of paint colors, stripes, and graphics, as well as different wheel and tire combinations. The interior can be upgraded with leather seats, modern tech such as touchscreen infotainment, and much more.
Increased resale value is another benefit of the fastback conversion. While it definitely won’t have the same value as an original F=astback, the looks, and performance will still make this a sought-after car for people who are more interested in style than the VIN digits.
(Note: VIN digits will still match the original coupe. One should never try to change the VIN digits. This is illegal and can result in serious legal troubles for the seller.)
In conclusion, the Mustang fastback is an iconic design, and the conversion from a coupe to a fastback is an excellent way to experience that iconic look for a lower cost. With the availability of customization options and the potential for increased resale value, the Fastback conversion is definitely worth considering for Mustang enthusiasts who desire both speed and aesthetics.
Performance Upgrades

Alright, now we’re getting to the good stuff: performance upgrades. Because let’s face it, what’s the point of having a badass-looking Fastback if you can’t rev the engine and go full speed ahead?
First up, let’s talk about engine and transmission improvements. Upgrading to a more powerful engine and making changes to the transmission can make a drastic difference in your Mustang’s speed and performance.
But let’s not forget about handling and control. After all, it’s great to go fast, but it’s even better to go fast AND be able to handle your car like a pro. Upgrading your suspension, brakes, and steering wheel can all lead to better handling and more control on the road.
And of course, we can’t forget about braking and safety features. After all, safety first, folks. Upgrading your brakes can lead to better stopping power, while safety features like airbags and reinforced frames can give you peace of mind while you’re flying down the highway.
Overall, if you’re going to invest in a Fastback conversion, it only makes sense to upgrade your Mustang’s performance as well. Trust us, once you feel the power of your new engine and the control of your upgraded handling, you won’t regret it.

Potential Drawbacks of a Coupe to Fastback Conversion
Let’s be real: A classic Ford Mustang coupe to fastback conversion is not a small project. There are some potential drawbacks to consider before jumping in. First, there’s the financial cost. The average cost of conversion (including purchasing the car) ranges from $8k to 20k+ depending on the extent of the upgrades, customization, and how much you’ll have to hire out. There are ways to get this number on the low end, but you’ll have to be ready for some work!
Moreover, the process of conversion is no joke, requiring significant time and labor involved. You’ll need to have the right expertise, tools, and equipment to pull it off without a hitch.
Finally, there may be technological challenges to overcome as well. Modifications to the engine, transmission, and other mechanical components aren’t always as straightforward as they seem.
I would be remiss if I didn’t mention this: the haters. You’re going to catch some hate for “ruining a coupe” or for driving a “fake fastback.” You’re going to have to decide beforehand to not give a damn what the haters think. No one is driving around with their VIN digits flashing. Everyone on the road is just going to see your gorgeous new Fastback and think what an amazing ride!
If all these potential drawbacks don’t scare you off, then you should absolutely take the plunge and complete a Mustang coupe to fastback conversion.
