Construction & Design

The GReddy Rocket Bunny Aero Kit is meticulously engineered using CAD technology to ensure precise fitment and aerodynamic performance. The components are crafted from high-quality fiberglass or composite materials, offering a lightweight yet robust structure that withstands daily driving and spirited use. The wide fenders and side panels are designed to align perfectly with the factory body lines, providing a seamless appearance once installed.

The kit’s aggressive styling is complemented by functional design elements that improve airflow around the vehicle, helping to reduce turbulence and increase downforce. The use of durable materials and careful construction techniques ensures longevity and resistance to cracking or warping over time. The aerodynamic enhancements not only improve the vehicle’s handling at high speeds but also contribute to a more commanding presence on the road.

Performance & Sound

While primarily focused on aesthetics and aerodynamics, the wide-body kit also supports performance upgrades by allowing wider tires and wheels, which can improve grip and cornering capabilities. The enhanced airflow and downforce contribute to better stability during spirited driving or track sessions. The kit does not alter engine performance directly but provides a solid foundation for further modifications.
