Preparing for Installation
Before installing your new rear diffuser, gather all necessary tools, including wrenches, screwdrivers, and any specific hardware that may come with the diffuser. Ensure your vehicle is parked on a flat surface, and consider using jack stands for better access.
Step-by-Step Installation
