Verus Engineering Rear Diffuser Panel Kit – Porsche 718 GT4

Fits Porsche 718 GT4, 718 GT4RS

$549.95

The Verus Engineering Rear Diffuser Panel Kit addresses the open areas left by the factory diffuser on the 718 GT4. While the OEM diffuser performs well, replacing the suitcase-style mufflers with an aftermarket exhaust creates a void that disrupts airflow and can act like a parachute, negatively impacting performance. By incorporating diffuser strakes and a precisely fitted panel, this kit helps manage the horseshoe vortices from the rear wheels, improving airflow and allowing the factory center diffuser to operate more efficiently.

During development, in-house scan data was used to achieve a near-OEM fit and finish, ensuring seamless integration with the vehicle. Advanced analysis tools were also utilized to validate performance improvements over the stock configuration.

Designed for drivers seeking a moderate increase in rear downforce along with reduced drag, this kit completes the rear diffuser system on the 718 GT4 for improved overall aerodynamic efficiency.

Note: Not compatible with OEM mufflers.

Description

Verus Engineering takes its name from the Latin word Verus, meaning true or complete, a reflection of the companyโ€™s philosophy that performance parts should be engineered as part of a complete system. Built by a team of passionate engineers, Verus focuses on applying sound engineering principles to solve complex performance challenges and deliver measurable improvements for high-performance vehicles.

Each Verus product is developed using advanced engineering tools and rigorous validation methods. Their aerodynamic components are designed using Computational Fluid Dynamics (CFD) to precisely model airflow, optimize pressure zones, and maximize aerodynamic efficiency before a product ever reaches production. These virtual simulations are paired with extensive real-world testing to ensure every component delivers meaningful gains in stability, cooling, and downforce.

The result is a line of motorsport-inspired components that blend cutting-edge engineering with proven track performance products built not just to look the part, but to function as highly effective aerodynamic solutions.
