Worldwide Direct. Premium Parts at Your Doorstep.
Elevate the aggressive stance and aerodynamic profile of your Tesla Model X with the CMST Carbon Fiber Rear Diffuser. This precision-engineered component is designed as a direct replacement for the factory rear bumper trim, adding a distinct, high-performance aesthetic that complements the SUV's modern lines. Specifically crafted for the refreshed Tesla Model X (2022 and onwards), this diffuser integrates seamlessly to deliver a factory-plus finish that is both visually striking and functional.
Constructed from authentic pre-preg carbon fiber, this CMST diffuser is cured in an autoclave under high pressure and temperature. This advanced manufacturing process results in a component that is not only exceptionally lightweight but also offers superior strength and thermal resistance compared to standard vacuum-infused carbon fiber. The part is finished with a high-quality UV-protection clear coat, which enhances the deep, glossy weave of the 3K (2x2) twill carbon fiber and provides long-term durability against the elements. The finish ensures a premium presentation that is as resilient as it is beautiful.
All CMST carbon fiber parts from AME Motorsport are backed by our commitment to quality, ensuring you receive a premium, fit-for-purpose aerodynamic enhancement for your vehicle.
