Our new Mustang GT500 style side skirt extensions are now available. This product is custom designed to fit the S650 Mustang GT & ECO models with Premium options or the Performance Pack. 

Crafted from HDPE with a matte texture finish to replicate the GT500's offering and installs with rivets. The opening around your pinch weld will remain open so you can still lift your car, and the product will have 1" of adjust-ability so you can choose how aggressive you would like the extensions to be. This product also matches up with our front GT500 style splitter winglet extensions.

Install Notes:

This product ships with rivets for install. You will need to mount the extension with self tapping screws so that you can align the remaining holes and match drill them so the rivets can be installed. 

Rock Guard extensions will need to be matched drilled once the side skirt is installed. The rock guard extensions will limit your adjust-ability of how far your side skirt extension can overhang.
