RS-R 2015 Ford Mustang EcoBoost Down Sus Springs

The RS-R Down Sus springs for your 2015 Ford Mustang EcoBoost are made from high-tensile steel, a strong material chosen for its ability to handle the stresses of lowering a performance vehicle. These springs are designed to give your Mustang a more aggressive look by lowering the ride height. You can expect a drop of about 1.2 inches in the front and 1.4 inches in the rear, which significantly changes the car's profile and can improve handling by reducing body roll during cornering.

RS-R has engineered these springs to work with your factory shock absorbers, making them a straightforward upgrade. The goal here is to achieve a sportier stance and a more connected feel to the road without requiring a full coilover system. The material choice means they are built to last and maintain their spring rate over time, providing a consistent ride height and improved handling characteristics for your EcoBoost Mustang.
