The Mercedes C63 AMG (W205) is a beast of a car straight from the factory blending intense power, clean style and the signature AMG growl you’d expect - all packed within a refined luxury body.
But, if you’re like most owners, stock isn’t enough.
You may be wanting an even more aggressive look, increased performance, or just some better lighting for your night drivers - and with the right modifications you can take you C63 to another level.
We’ve compiled a list of the best upgrades for your W205 to help you take it to that next level, including exterior styling, performance enhancements, and lighting upgrades that are actually worth your money.
Exterior Styling Upgrades for the C63 AMG
One of the best things about owning a C63 AMG is making it your own.
And with exterior upgrades, you can not only improve your car’s aggressive look, but can also enhance the aerodynamics and functionality of your vehicle.
That said, when considering different mods, you need to balance aesthetics with quality to ensure you’re not stuck with something that might face, crack or potentially break under pressure.
Higher grade materials like carbon fiber ensure longevity and maintain the premium feel of your Mercedes.
Below are some of the most popular and effective exterior styling upgrades for the W205.
Front Grilles (GT, GTR, and Panamericana Styles)
The front grille is the face of the C63 AMG, and swapping out the stock grille for a more aggressive design can dramatically change the car’s presence on the road.
Installation of these grills are generally pretty straightforward, and are designed to fit perfectly without the need for extensive modifications.
A front grille not only elevates your car’s aesthetics but it can also improve cooling efficiency, especially when paired with other performance upgrades.
Front Lips & Splitters
Adding a front lip or splitter is a popular way to enhance the aerodynamics of the C63 AMG while giving it a lower, more aggressive stance. These components help to reduce lift at high speeds, improving stability and handling and give the car a completely new look.

Carbon fiber front lips and splitters are particularly favored due to their lightweight nature and striking appearance.
Rear Diffusers
A W205 rear diffuser is another popular feature for both style and performance. It helps with airflow from underneath the car, reducing drag while also adding a sporty look to the rear end of your car.
Carbon Fiber Trunk Spoilers
Adding a spoiler to the trunk lid is a classic way to improve both aesthetics and aerodynamics. It’s often the go to upgrade for new car owners as it’s often more affordable and really changes the look of your car.
Carbon fiber spoilers are especially popular due to their lightweight yet strong build, which also adds a distinct look to your C63.

Choosing the right spoiler for your car is important as a well-integrated spoiler enhances the overall design without appearing oversized or out of place.
Carbon Mirror Caps
For a subtle yet effective styling upgrade, carbon fiber mirror caps are an excellent choice. These small details can elevate the car’s sporty character and tie together other carbon fiber elements like spoilers and diffusers.
Mirror caps are relatively easy to install and offer a quick way to add a touch of exclusivity. They also help prevent wear and tear from the elements, while maintaining a glossy look over time.
Performance Mods for the C63 AMG
The C63 doesn’t exactly hold back in stock form - but if you want to go that next level, performance modifications can easily unlock even more potential.
Whether it’s a new exhaust system, upgraded cooling or fresh downpipes, these mods improve power & throttle response, and overall making driving a dream.
But the real magic happens when you start stacking these upgrades together. Combining upgrades together often complement one another and result in a more exhilarating driving experience.
Here are some of the best performance enhancements for the W205 C63 AMG.
Valved Sport Exhaust System
If you’re wanting to really make a mark on your C63 AMG, a valved sport exhaust system is the way to go. One of the most popular mods on the market, this upgrade not only makes the car obnoxiously loud, but it improves exhaust flow which is better for engine efficiency.
The valved system allows you to switch between a quieter mode for everyday driving and a louder, more aggressive sound for tearing up the streets.

Race Pipes / Downpipes
Race pipes and downpipes are critical components for enhancing exhaust flow and reducing turbo lag, especially on the twin-turbocharged V8 found in the C63 AMG.
It’s important to note that some race pipes and downpipes may affect emissions compliance, so checking local regulations before installation is advisable.
Air Intake System
Improving the air intake system is another effective way to boost the C63 AMG’s performance. High-flow air intakes help the engine to breathe more freely, which increases the amount of cool air entering the combustion chamber.
This results in better combustion efficiency, improved throttle response, and often a slight increase in horsepower.
High-Performance Intercooler
The intercooler plays a vital role in cooling the compressed air from the turbochargers before it enters the engine. Upgrading to a high-performance intercooler significantly improves the power output and engine reliability of your vehicle.
Investing in a quality intercooler ensures that the C63 AMG’s engine stays cool and performs optimally, even when pushed to its limits.
Lighting Upgrades
Fresh lights are a practical and stylish way to upgrade your AMG’s appearance as they not only give your car a new look, but they improve visibility and safety - especially for those long night drives.
Advanced LED technology has made it easier than ever to upgrade both the front and rear lighting systems with more sleek and efficient options available.
LED Taillights (Sedan & Coupe)
Replacing the stock taillights with LED units is a popular upgrade for C63 AMG owners seeking a contemporary look. LED tail lights are brighter, respond faster, and have great energy efficiency compared to your stock bulbs.
Installing LED taillights is relatively simple and offers an immediate visual upgrade, making an affordable and worthwhile modification for your C63.
So Which Mod You Should Get?
When deciding which modifications your Mercedes C63 AMG deserves, you should look at your budget and priorities - understanding whether you’re chasing visual upgrades, performance upgrades, or both.
For those new to modifying their W205, starting with an upgrade that offers a balance of visual impact and driving enjoyment is often the best approach (something like a carbon fiber spoiler or mirror caps).
A valved sport exhaust system is a highly recommended first mod if you’ve got the budget and are chasing better performance.
On the styling front, swapping out your front grill for a GTR style or Panamericana style grille can instantly transform the look of your car, without the complicated installation - making it another popular choice.
Ultimately, the best mods are those that align with your personal vision for your car, and your driving habits.
