Modern Aggressive RTR Styling

These RTR Rear Quarter Panel Splitters were engineered to give your Mustang an aggressive street/track appearance. Designed and developed in conjunction with Vaughn Gittin Jr., these RTR Quarter Splitters are meant to be installed along with RTR's Side Rocker Splitters. Featuring a clean, sleek appearance, these Splitters are the same exact ones available on the 2018 - 2022 Mustang RTR.

High-Quality TPO Construction

RTR manufactures its Rear Quarter Panel Splitters from an injection molded thermal plastic olefin (TPO) material using the original OEM CAD data from Ford to ensure a perfect fit. TPO is an extremely strong material known for its light-weight, superior durability, and impact resistance - making it perfect to withstand the hazards of daily driving. These Splitters are completed in a fine-grained stippled texture for a factory look that helps to hide the appearance of rock and stone impacts.

Straight Forward Installation

RTR's Quarter Panel Splitters were designed to be a simple install with only minor drilling required. These RTR Splitters include all the required hardware needed for an easy straight forward install. Installation can be completed in about an hour with just basic hand tools. Even though drilling is required, these Quarter Panel Splitters can be removed without issue or damage.
