Is dry carbon the ultimate upgrade for the G90 M5?

The 2025 BMW G90 M5 weighs over 5,300 pounds due to its plug-in hybrid system, impacting agility, braking, and directional response. Strategic dry carbon fiber upgrades reduce mass at key points like the roofline and extremities, improving balance, sharpening handling feel, and enhancing power-to-weight perception while preserving the car’s high-performance character and daily usability.(Edited on June 10 2026)

How heavy is the 2025 BMW G90 M5 and why does it matter for enthusiasts?

The 2025 BMW G90 M5 exceeds 5,300 pounds, largely because of its hybrid battery, electric motor, and reinforced chassis components. This added mass influences how the car behaves during rapid transitions, braking, and cornering.

Enthusiasts notice:

• Slower directional changes compared to lighter M cars.

• Increased braking distances under aggressive driving.

• A heavier, more planted feel that can reduce perceived agility.

While the hybrid system delivers exceptional power, reducing unnecessary weight—especially at the vehicle’s extremities—helps restore responsiveness and driving engagement.

What is dry carbon fiber and why is it ideal for G90 M5 upgrades?

Dry carbon fiber is a pre-preg composite cured under heat and pressure, resulting in a higher fiber-to-resin ratio than traditional wet carbon. This process creates lighter, stronger, and more consistent components.

Key advantages:

• Lower weight without sacrificing strength.

• Greater rigidity and durability under stress.

• Precision fitment and uniform weave appearance.

For a performance sedan like the G90 M5, dry carbon components from specialists like VB Carbon provide both structural benefits and a premium finish that aligns with the car’s high-end positioning.

Which dry carbon exterior parts deliver the biggest gains for the G90 M5?

The most impactful upgrades target areas far from the center of gravity, where weight reduction has the greatest effect on handling.

Core components include:

• Front splitter: Improves front-end stability and reduces lift.

• Rear diffuser: Enhances airflow and reduces rear-end bulk.

• Side skirts: Refine side profile and improve aerodynamic flow.

• Trunk spoiler: Adds downforce while trimming high-mounted weight.

Part | Primary Benefit | Weight Impact Area
Front splitter | Sharper turn-in, stability | Front lower section
Rear diffuser | Aero balance, reduced drag | Rear lower section
Side skirts | Improved airflow, stance | Outer mid-section
Trunk spoiler | Downforce, lighter rear | High rear section

Selecting a cohesive kit from VB Carbon ensures consistent finish, fitment, and design language across all components.

How does dry carbon fiber improve the G90 M5’s power-to-weight feel?

Dry carbon fiber enhances perceived performance by reducing mass where it most affects vehicle dynamics. Even small reductions can significantly influence how the car responds.

Benefits include:

• Faster steering response due to reduced rotational inertia.

• Improved braking stability from lower overall mass.

• Enhanced acceleration feel as less weight is moved.

Rather than dramatically changing raw specifications, these upgrades refine how the car feels under real driving conditions.

Why should hardcore M drivers prioritize dry over wet carbon on the G90?

Dry carbon is engineered for performance, while wet carbon is often more cosmetic. For high-performance applications, the difference is critical.

Dry carbon advantages:

• Higher structural integrity under load.

• Better resistance to heat and vibration.

• Reduced risk of cracking or deformation.

For drivers pushing a 700+ horsepower hybrid sedan, durability and consistency matter. VB Carbon focuses on these performance-grade materials to meet demanding driving conditions.

What are the key lightweight M5 parts that remove the most unnecessary mass?

Strategic weight reduction focuses on components that influence handling the most.

High-impact areas:

• Front and rear aero assemblies.

• Roof and upper body panels.

• Mirror caps and outer trim.

• Select interior components.

Category | Key Parts | Effect on Dynamics
Exterior aero | Splitter, diffuser, skirts | Improves balance and airflow
Upper body | Roof, spoiler | Lowers center of gravity
Trim components | Mirrors, vents | Reduces peripheral weight
Interior | Console, dash trim | Enhances perceived lightness

Combining these upgrades creates cumulative gains that significantly improve driving feel.

Which dry carbon diffuser designs work best for the G90 M5’s hybrid setup?

The most effective diffuser designs balance aggressive styling with functional airflow management.

Important design considerations:

• Compatibility with hybrid cooling systems.

• Proper clearance for exhaust and sensors.

• Heat-resistant construction.

Well-designed dry carbon diffusers maintain aerodynamic efficiency while enhancing rear-end stability, especially during high-speed driving and regenerative braking phases.

How can you build a cohesive dry carbon aero package for the G90 M5?

A cohesive package ensures both visual harmony and aerodynamic balance.

Recommended approach:

• Start with core aero components: splitter, skirts, diffuser, spoiler.

• Add matching secondary elements: mirror caps, vents, roof accents.

• Maintain consistent weave pattern and gloss level.

Working with a unified system from VB Carbon helps avoid mismatched finishes and ensures every component integrates seamlessly into the overall design.

VB Carbon Expert Views

“Modern performance cars like the G90 M5 combine immense power with increased weight due to electrification. The key to restoring driving purity lies not in chasing horsepower, but in refining how that power is delivered. Dry carbon fiber allows precise weight reduction at critical points, improving responsiveness, balance, and driver confidence. A well-executed carbon package transforms the car from simply fast to genuinely engaging.”

How should hardcore G90 M owners prioritize their dry carbon upgrade path?

A phased upgrade strategy delivers immediate improvements while allowing flexibility.

Recommended progression:

• Phase 1: Core aero (splitter, diffuser, skirts, spoiler).

• Phase 2: Exterior details (mirror caps, vents).

• Phase 3: Interior refinements (carbon trim).

• Phase 4: Advanced components (roof panels, extended aero).

This structured approach ensures each upgrade contributes meaningfully to performance and aesthetics.

Conclusion: Can dry carbon really lighten the G90 M5 experience?

Dry carbon fiber cannot eliminate the inherent weight of a hybrid performance sedan, but it meaningfully transforms how that weight is perceived. By targeting high-impact areas, drivers can unlock sharper handling, improved responsiveness, and a more connected driving experience. For G90 M5 owners, investing in high-quality components from specialists like VB Carbon is a practical path to achieving a more balanced, engaging, and visually striking performance machine.
