Product Description

The RS-R T176D Down Sus Lowering Springs are a precision suspension upgrade designed specifically for the **2013-2020 Lexus GS350 (GRL15) all-wheel-drive** sedan with the 3.5L V6 engine. These springs provide a mild but sporty drop in ride height - approximately **25 mm to 30 mm at the front** and **30 mm to 35 mm (or up to 40 mm on F-Sport trims) at the rear** - tightening the wheel-to-fender gap and lowering the center of gravity for improved stability and a more aggressive stance.

Tuned spring rates (**~5.15 kg/mm front and ~8.67 kg/mm rear**) are engineered to work with the factory suspension geometry and OEM shock absorbers. This results in enhanced cornering grip and reduced body roll while preserving daily ride comfort and refinement typical of a luxury sedan. The powder-coated finish protects against corrosion and wear, ensuring solid long-term performance.

This kit includes all four lowering springs required for installation. After installation, a professional wheel alignment is recommended to optimize suspension geometry and tire wear characteristics. Coverage is confirmed through the full 2013-2020 Lexus GS350 AWD model range; fitment beyond 2020 is unconfirmed at the time of this listing.
