Product Description

The RS-R Down Sus T973D is a vehicle-specific lowering spring set engineered for the 2025-2026 Toyota Crown Signia. Developed using the factory suspension geometry, OEM shock dampening curves, and stock ride height as a baseline, RS-R calibrates the spring rates to deliver a noticeable drop - approximately 30-35mm front and 35-40mm rear - without overloading the stock dampers or compromising ride quality. The result is a cleaner, lower stance and improved handling response that feels at home on both daily commutes and weekend drives.

Installation is straightforward, as the T973D springs are designed as direct replacements for the OEM units with no modifications needed. The front spring rate of 2.86 kg/mm and rear rate of 6.12 kg/mm are specifically matched to the Crown Signia's AWD hybrid chassis, preserving alignment geometry within factory tolerances at the recommended drop. Backed by a 3-year / 36,000-mile warranty and manufactured in Japan, this is the most accessible first step for Crown Signia owners looking to improve stance and handling without committing to a full coilover system.
