9Trevora PR-1 Carbon Body Kit for G9x BMW M5

The TREVORA PR-1 kit is the result of more than six months of dedicated development for the G90 and G99 M5 platform, built on over a decade of carbon fiber aero design experience. The use of 3D CAD combined with real-world body scanning of the G90 and G99 bodywork means the fit of each component is derived from the actual geometry of the car rather than from digital models alone; a distinction that matters on a vehicle with the panel fit expectations of the current M5. The PR-1 front splitter introduces sharp aerodynamic lines at the lower front bumper that increase front-end downforce while complementing the assertive visual presence of the G90 front fascia. The splitter geometry connects directly with the front bumper duct extensions, which refine the front-end airflow path and integrate cleanly with the overall front aero treatment. Together, the splitter and duct extensions address the front of the car as an aerodynamic system rather than as individual components. The side skirts follow the M5’s natural shoulder line, adding stance and visual width to the lower body without introducing elements that work against the G90 and G99’s premium character. On a car the size of the M5, proportion matters; the PR-1 skirts are developed to enhance the body’s existing lines rather than impose a separate aesthetic onto them. At the rear, the three-element diffuser manages underbody airflow beneath the rear bumper, contributing to rear stability while providing one of the most visually substantial rear treatments available for the G90 and G99 platform. The three-element construction creates depth and aerodynamic presence that a single-element alternative cannot match.

Carbon Fiber Construction

• Constructed using high-quality autoclave-cured pre-preg carbon fiber for superior strength-to-weight ratio. Each component is engineered and prototyped in-house using advanced CAD modeling and 3D scanning to achieve precise factory-plus fitment. A UV-resistant clear coat protects the clean weave pattern and maintains finish quality over time, ensuring long-term durability in both daily driving and high-performance environments.

Frequently Asked Questions

• What vehicles is the TREVORA PR-1 Carbon Body Kit compatible with? The PR-1 Carbon Body Kit is compatible with the 2024 and newer BMW M5 Sedan G90 and the 2024 and newer BMW M5 Touring G99. All four components are developed around the shared front and rear bumper architecture of both body styles. Confirm bodywork compatibility for pre-facelift versus facelift variants with Bulletproof Automotive before ordering.
• What is included in the PR-1 Carbon Body Kit? The kit includes four components: the PR-1 pre-preg carbon fiber front splitter, the PR-1 pre-preg carbon fiber side skirt set (left and right), the PR-1 pre-preg carbon fiber three-element rear diffuser, and the PR-1 pre-preg carbon fiber front bumper duct extension set.
• Why did the development of this kit involve real-world body scanning? 3D CAD design alone relies on digital models of the vehicle, which can differ from the actual manufactured bodywork in subtle ways that affect panel fit at the component edges. Real-world body scanning captures the exact geometry of the physical G90 and G99 bodywork, allowing TREVORA to develop each component against the actual car rather than a digital approximation. This results in fitment that holds to the same tolerance expectations as factory body panels, which matters on a vehicle where panel gaps are as carefully controlled as they are on the current M5.
• What is the three-element rear diffuser and why does it matter aerodynamically? The three-element rear diffuser uses three separate horizontal elements across the lower rear bumper rather than a single flat panel. Multiple elements generate a larger effective diffuser area for underbody airflow management, creating a more efficient pressure recovery zone beneath the rear of the car and contributing to increased rear stability at speed. The three-element construction also delivers greater visual depth at the rear than a single-element alternative, which is appropriate for a car of the G90 and G99 M5’s standing.
• How do the front splitter and front bumper duct extensions work together? The front splitter and front bumper duct extensions are developed as a paired aerodynamic system for the front end of the PR-1 kit. The splitter increases front-end downforce by generating a pressure differential beneath the front bumper. The duct extensions refine the airflow path into the front bumper openings, improving the efficiency of the air management at the front of the car and integrating cleanly with the splitter geometry so the full front end reads as a coherent aerodynamic treatment.
• How does the PR-1 kit compare to the individual PR-1 components available for the G90 and G99? Individual PR-1 components for the G90 and G99, including the front splitter, side skirts, front bumper duct extensions, and rear spoiler, are available as standalone purchases. The PR-1 Carbon Body Kit combines all four in a single purchase and ensures consistent production batch and finish quality across every component in the kit. It also includes the three-element rear diffuser, which is the most aerodynamically comprehensive rear treatment in the PR-1 G90/G99 lineup.
