What Does a Rear Diffuser Do?

A rear diffuser enhances the airflow underneath your vehicle, helping to reduce drag and improve stability at speed. It also transforms the rear-end appearance by adding a more aggressive, performance-inspired look.

Are your rear diffusers real carbon fibre?

Many of our rear diffusers are manufactured from genuine pre-preg or high-quality carbon fibre, offering exceptional strength, lightweight construction, and a premium gloss finish. Material specifications are listed on each product page.
What’s the difference between OEM+ and performance style diffusers?
