RS*R T973D Down Sus Lowering Springs

The RS*R T973D Down Sus Lowering Springs deliver a mild, street-friendly drop while preserving the comfort and drivability of your factory suspension setup. Engineered specifically for the Toyota Crown Signia, these springs are designed to close the fender-to-wheel gap and improve overall stance without sacrificing daily usability.

RS*R engineers account for the vehicle's factory suspension geometry, shock dampening characteristics, spring rate, and stock ride height when developing each Down Sus application — ensuring a precision fit that works in harmony with your OEM shocks and struts. The result is a balanced upgrade that reduces body roll, lowers the center of gravity, and improves cornering response while remaining comfortable on the street.
