Description
Designed specifically for 2015-2023 Ford Mustang Ecoboost, RS-R Down Sus Lowering Springs reduce factory ride height with spring rates selected around the application. They suit drivers who want a more purposeful stance while keeping a conventional fixed-height suspension setup.
Why Choose RS-R Down Sus?
Down Sus is RS-R's standard lowering-spring line, developed around each vehicle's factory suspension geometry, damper behavior, spring rate and target ride height. It is the sensible choice when the goal is a cleaner stance and a more tied-down feel without replacing the complete damper assembly.

Before Ordering
Lowering springs are fixed-height components. Final ride height can vary with vehicle condition, factory options, mileage and load, so published drop figures should be treated as approximate.
