Product Description

The RS-R Down Sus Lowering Springs (Part T996D) are vehicle-specific performance springs engineered for Lexus RC300 and RC350 models with all-wheel drive from 2015 through 2024. These springs provide a mild lowered ride height - around 20-25 mm at the front and 5-10 mm at the rear - giving the RC a more aggressive stance and lower center of gravity while maintaining everyday comfort.

Designed to match factory suspension geometry and damping characteristics, the springs reduce body roll and improve handling without harsh ride quality. The durable powder-coated finish ensures long-term corrosion resistance, and the springs integrate directly with OEM shock absorbers and stock mounting points for straightforward installation. Alignment is recommended after installation to ensure optimal handling and tire wear.
