Overview

The factory 718 GT4 rear diffuser performs well — until you swap the suitcase-style mufflers for an aftermarket exhaust. At that point the bumper becomes a parachute and hurts vehicle performance.

This kit fills that void. Using diffuser strakes and a properly fitted panel, it contains the horseshoe vortices coming off the rear wheels, improving performance and ensuring the factory centre diffuser gets clean airflow.

In-house scan data gives a near-OEM fit and finish, and analysis software confirmed the improvement over the OE setup.

Important: not compatible with OEM mufflers. This kit is specifically for cars running an aftermarket exhaust.
