Installation
V7 Motorsports recommends that all exterior auto body parts, including but not limited to spoilers, diffusers, and any other components made of carbon fiber or other materials, be installed by a qualified and experienced professional. Incorrect installation can lead to damage, improper fitment, or potential safety hazards. V7 Motorsports is not responsible for any damage or injury resulting from improper installation or misuse of our products. By choosing to install the product yourself, you assume all responsibility for any resulting issues or complications.

Carbon Fiber
All carbon fiber parts offered by V7 Motorsports are crafted from genuine high-quality materials for aesthetic and performance enhancements. Due to the inherent nature of carbon fiber and the manufacturing process, there may be slight variances in weave patterns, fitment, or finish between individual parts. Prolonged exposure to sunlight and external elements may affect the appearance of carbon fiber products over time. For the best longevity and appearance, consider professional installation and regular maintenance.
