The ZL1 Addons Full Body Kit for the 2018–2023 Mustang GT Performance Pack (Standard Body) delivers an aggressive, track-ready appearance with real aerodynamic function. Each kit is made in the USA from high-quality ABS materials and designed for a straightforward installation with no major modifications required.
The front splitter is built from 3/8” ABS with a textured top surface and a dimpled smooth underside for airflow and durability. The side skirts and rear extensions are crafted from 1/4” ABS, giving the kit a perfect balance of strength, weight, and style.
Unlike other kits that install at a positive angle of attack, ZL1 Addons splitters maintain proper geometry, delivering real aerodynamic performance while retaining OEM fitment.
