RS-R Lowering Springs

The RS-R Down Sus lowering springs, part number T172D, are engineered to offer both a refined aesthetic and enhanced handling for your vehicle. As the number one aftermarket spring manufacturer in Japan, RS-R brings extensive technology and expertise to the U.S. market. Unlike springs that offer only a superficial drop, RS-R considers the specific characteristics of each vehicle, including factory suspension geometry, shock dampening, spring rates, and ride height levels. These specific Down Sus springs aim to provide a lowered stance and improved handling. They achieve an approximate front drop of -25mm to -30mm (-1.0in to -1.2in) and a rear drop of -35mm to -40mm (-1.4in to -1.6in). The spring rates are set at 5.15kg/mm for the front and 8.98kg/mm for the rear, carefully selected to complement the vehicle's original suspension setup for a balance of performance and comfort. This set of T172D springs is specifically designed for the 2016+ Lexus GS350 RWD model with the F-Sport package, identified by the chassis code GRL12.
