Product Description

The RS-R F407D Down Sus lowering spring set is engineered specifically for the 2024 Subaru WRX TR on the VBA chassis. Unlike springs designed for the standard WRX, F407D is calibrated around the TR's unique factory suspension specification and is intended to lower the vehicle while maintaining a balanced combination of handling performance and street comfort.

The set provides an approximately 0.6-0.8-inch front drop and 0.8-1.0-inch rear drop. The lower ride height reduces the center of gravity and helps improve cornering response and body-roll control while retaining compatibility with the factory strut and shock assemblies. The springs are designed as direct OE replacements.

F407D includes four springs for complete front and rear installation. It is exclusively intended for the 2024 WRX TR and should not be substituted for the standard WRX or WRX STI applications. A professional four-wheel alignment should be performed after installation to account for changes in suspension geometry and ride height.
