Carbon Fibre vs Gloss Black Body Kits: Which Should You Choose?

Carbon fibre or gloss black—which body kit finish is best for your car?

The short answer is simple: choose carbon fibre for a more exclusive, motorsport-inspired appearance; choose gloss black for an affordable, practical OEM+ upgrade.

However, the right option also depends on your car, budget, driving habits and the quality of the part itself. A well-made gloss black splitter can be a better purchase than a low-quality carbon fibre alternative that does not fit correctly.

In this guide, the KITS UK team compares carbon fibre and gloss black body styling parts across price, appearance, durability, weight, maintenance and everyday usability.

Carbon Fibre vs Gloss Black: Quick Comparison

What Is a Carbon Fibre Body Kit?

A carbon fibre body kit uses carbon-fibre-reinforced material to create parts such as:

• Front splitters
• Rear diffusers
• Side skirts
• Boot spoilers
• Roof spoilers
• Canards
• Mirror covers
• Grilles and exterior trim

The visible woven pattern creates the distinctive motorsport appearance associated with performance models such as the BMW M2, M3 and M4, Mercedes-AMG vehicles and other high-performance cars.

However, not every product sold as “carbon fibre” is constructed in the same way. Depending on the manufacturer and price, a part may be:

• Full carbon fibre
• Carbon fibre over a composite structure
• Carbon fibre skinned
• Hydro-dipped or carbon-look plastic

This distinction affects weight, strength, price, finish and fitment. Before purchasing, check the product description carefully rather than relying only on the words “carbon style” or “carbon look”.

What Is a Gloss Black Body Kit?

Most gloss black styling parts are manufactured from ABS plastic or another automotive-grade composite and finished in high-gloss black.

They are designed to create a clean, factory-inspired appearance without the higher cost of genuine carbon fibre.

Gloss black is particularly effective on vehicles that already have black exterior details, including:

• Kidney grilles
• Window surrounds
• Mirror caps
• Badges
• Exhaust trims
• Factory black styling packages

For BMW M Sport and Mercedes-AMG Line models, gloss black parts often blend naturally with the car’s original trim, producing an OEM+ appearance rather than making the vehicle look heavily modified.

Which Is More Expensive?

Carbon fibre is normally the more expensive option because of its material, manufacturing process and finishing requirements.

A carbon fibre splitter, diffuser or spoiler can cost considerably more than the equivalent gloss black part. The difference becomes even larger when combining several pieces into a complete body kit.

Gloss black is generally the better choice when you want to upgrade several areas of the vehicle within a controlled budget. Instead of spending most of the budget on one carbon fibre component, you may be able to install a matching splitter, side extensions, diffuser and spoiler in gloss black.

Current KITS UK pricing varies by vehicle and product. For example, our BMW G20 and G21 collection includes individual gloss black styling parts alongside complete performance packages, allowing customers to build the car in stages or purchase a coordinated package.

Price winner: Gloss black

Gloss black offers the strongest visual transformation for the money. Carbon fibre costs more but can provide a more exclusive finish when product quality and fitment are both high.

Is Carbon Fibre Always Lighter?

Genuine carbon fibre components are normally lighter than equivalent solid plastic or fibreglass parts. However, the real-world difference depends on how the product is constructed.

A carbon-skinned component with a heavier composite core may not provide the same weight advantage as a properly manufactured full-carbon part. On small styling pieces such as mirror caps or spoilers, the weight difference may also be too small to noticeably affect a road car’s performance.

For most KITS UK customers, appearance, fitment and durability matter more than saving a small amount of weight.

If weight reduction is your main objective, confirm the exact construction and product weight before ordering.

Weight winner: Carbon fibre—but only when comparing equivalent, correctly manufactured parts

Which Is More Durable?

This is where the answer becomes more complicated.

Carbon fibre has an excellent strength-to-weight ratio, but that does not mean every carbon fibre styling part is impossible to damage. A low front splitter can still crack or chip after contact with:

• Speed bumps
• High kerbs
• Road debris
• Steep driveways
• Parking stops

Carbon fibre parts are also normally more expensive to repair or replace.

ABS gloss black parts can flex more under light impact, depending on their design and thickness. They are not damage-proof, but replacing a gloss black splitter is normally less painful financially than replacing a premium carbon fibre one.

For a daily-driven car that regularly encounters UK speed bumps, narrow roads and uneven surfaces, gloss black is often the more practical option.

Everyday durability winner: Gloss black

Strength-to-weight winner: Quality carbon fibre

Which Finish Is Easier to Maintain?

Both finishes need proper care.

Carbon fibre maintenance

To protect carbon fibre parts:

• Wash them with a pH-neutral car shampoo.
• Avoid aggressive brushes and abrasive cleaners.
• Use a clean microfibre towel.
• Protect the clear coat with a suitable sealant or ceramic coating.
• Inspect low-mounted parts regularly for chips or damage.

The carbon weave is normally protected by a clear coat. If that coating becomes damaged or deteriorates, the finish can lose clarity or develop a cloudy appearance.

Gloss black maintenance

Gloss black is easy to clean but can reveal:

• Fine scratches
• Swirl marks
• Water spots
• Dust
• Poor washing technique

Use a soft wash mitt and clean microfibre towels. Avoid automatic car washes with abrasive brushes if you want to preserve the gloss finish.

Maintenance winner: Draw

Gloss black is cheaper to replace, but both surfaces need careful washing to remain in their best condition.

Which One Looks Better?

This comes down to the style you want to create.

Choose carbon fibre if you want:

• A more aggressive, performance-focused look
• Visible motorsport influence
• A premium finish for an M, AMG, S or RS model
• Styling that stands out at shows and meets
• Exterior parts that complement carbon interior trim

Carbon fibre works particularly well when used consistently. A carbon splitter, side skirts and diffuser will usually look more intentional than one isolated carbon part surrounded by unrelated finishes.

Choose gloss black if you want:

• A clean OEM+ appearance
• Styling that complements factory black trim
• A subtle but noticeable transformation
• A consistent finish across several exterior parts
• A practical setup for a daily-driven vehicle

Gloss black works especially well on lighter paint colours such as white, grey, blue and red because it creates a strong contrast. On a black car, it produces a more subtle and integrated appearance.

Appearance winner: Personal preference

Carbon fibre is more distinctive. Gloss black is cleaner and easier to integrate into most builds.

Is Carbon Fibre Worth the Extra Money?

Carbon fibre is worth considering when:

• You own a performance-focused model.
• The car is a long-term build.
• You care about genuine material and weave quality.
• You are prepared to maintain the finish properly.
• The additional replacement cost would not be a major concern.
• You are purchasing from a supplier with reliable fitment information.

It may not be the best investment when:

• The car is used daily on poor roads.
• You frequently park near high kerbs.
• Your main goal is simply to improve the car’s appearance.
• You want to upgrade several areas within a limited budget.
• You are considering an unverified low-cost carbon part.

The material alone does not guarantee a good result. Correct shape, mounting points, finish quality and professional installation are just as important.

Can You Mix Carbon Fibre and Gloss Black?

Yes—but it should look deliberate.

A common approach is to use gloss black for larger or more exposed components and carbon fibre for selected details. For example:

• Gloss black splitter with carbon mirror caps
• Gloss black side extensions with a carbon boot spoiler
• Gloss black grille with a subtle carbon diffuser
• Gloss black body kit with carbon interior trim

Try to avoid using too many unrelated finishes. Mixing gloss black, matte black, carbon fibre and chrome across the same vehicle can make the styling feel inconsistent.

For the cleanest result, choose one dominant finish and use the second as an accent.

What Should Daily Drivers Choose?

For most daily-driven BMW, Mercedes, Audi and Tesla models, gloss black is the more sensible choice.

It delivers a noticeable transformation, matches factory styling and costs less to replace if a low-mounted part becomes damaged.

Carbon fibre is better suited to customers who want a more premium build and accept the additional purchase and replacement costs.

Our practical recommendation is:

• Daily driver: Gloss black
• Budget-conscious full build: Gloss black
• Show car: Carbon fibre
• Performance-focused build: Carbon fibre
• Car exposed to frequent speed bumps: Gloss black
• Subtle OEM+ styling: Gloss black
• Maximum visual exclusivity: Carbon fibre

Does Professional Fitting Matter?

Yes. The quality of the installation can make a greater visual difference than the material itself.

Incorrect fitting can cause:

• Uneven panel gaps
• Poor alignment
• Unnecessary drilling
• Loose mounting points
• Vibration at speed
• Damage to the part or vehicle
• Premature cracking around fixings

Carbon fibre requires particularly careful handling because excessive pressure around the mounting points can damage the component.

KITS UK Verdict

There is no single finish that is best for every vehicle.

Choose gloss black if you want an affordable, clean and practical body kit that suits everyday driving. It is the best all-round choice for most BMW, Mercedes, Audi and Tesla owners.

Choose carbon fibre if you want a more exclusive motorsport look and are comfortable paying more for the material, finish and replacement cost.

Most importantly, choose a part made specifically for your vehicle and confirm its compatibility before ordering. A correctly fitted gloss black kit will always look better than a poor-quality carbon fibre part with bad alignment.
