Intimidating Shelby GT500 Inspired Styling

Transform the exterior of your S550 Mustang with the MP Concepts GT500 Style Mustang Rear Diffuser. This kit closely resembles the rear fascia of the GT500 and gives your Mustang the popular aggressive look of Shelby Mustang GT500.

Constructed from Durable OEM Quality ABS 

This premium style rear is manufactured from OEM quality Acrylonitrile butadiene styrene (ABS). ABS is renowned for being a strong and durable thermoplastic polymer.

This feature gives it an aggressive look and better durability while also being lightweight.

This kit only comes with the rear diffuser. The reverse lights and the side markers are not included in the kit – these will be carried over from your Mustang.

The straightforward bolt-on installation can be done within two hours. For this installation, some of the original hardware will be reused.
