Stack Performance Carbon Fiber Charger Diffuser
Stack Performance has teamed up with one of the worlds best aerodynamics companies to combine strengths and offer a superior product.
Diffusers work in conjunction with other aerodynamic components of a car to help produce downforce. Because a car displaces air as it moves forward, the air molecules in the rear of the car get disrupted causing a vacuum of low pressure air.
To help channel the high speed air flow coming from underneath the car, diffusers redirects the high speed air flow to transition smoothly transition into the low pressure vacuum in the rear. This encourages a smoother flowing air flow underneath the car and allows better performance from other aerodynamic components such as aerodynamic spoilers.
We have designed all of our spoilers for track use and to outperform your competitors not running a true spoiler.
Our diffusers are made of 100% Carbon Fiber. All of our Carbon Fiber products are made from 1st quality Carbon Fiber, not 2nd or 3rd quality. This is a direct carbon fiber replacement, not an overlay on top of factory parts.
