Introducing LVA's most advanced aerodynamic product yet! A true chassis-mounted rear diffuser engineered specifically for the S650 Mustang platform. This isn't just another flimsy bumper-mounted diffuser; it's a performance-driven solution that secures directly to your vehicle's chassis using four proprietary metal brackets for unparalleled strength and stability.
Extending three feet under the rear bumper and tying into the rear differential mount, this diffuser eliminates the trapped airflow between the spare tire well and rear bumper cover. The result? Reduced drag, increased rear-end stability, and a clean airflow path optimized with a three-degree angle of attack for maximum efficiency. Built from our patented Hybrid Aluminum and CNC machined in-house at our Indiana facility, this diffuser delivers an OEM-plus fit and finish with track-tested performance.
