Down Sus Lowering Springs

The RS-R Down Sus Lowering Springs (part number T171D) are engineered to enhance the handling and aesthetics of your 2013-2015 Lexus GS350 RWD (chassis code GRL10). With a front spring rate of 5.15kg/mm and a rear spring rate of 8.67kg/mm, these springs offer a firm yet compliant ride, suitable for daily driving and spirited performance. The front of the vehicle can expect a drop of approximately -25mm to -30mm (-1.0 to -1.2 inches), while the rear will see a drop of about -30mm to -35mm (-1.2 to -1.4 inches). For F Sport models, the drop is slightly less pronounced, with the front dropping -10mm to -15mm (-0.4 to -0.6 inches) and the rear -10mm to -15mm (-0.4 to -0.6 inches). This product is backed by a 3-year/36,000-mile warranty. It is important to confirm fitment before placing an order to avoid potential issues. If a fitment issue arises due to a recommendation from the sales team, the product may be eligible for return without restocking fees, provided it is in like-new condition. Note that for wheel-only orders or wheel and tire packages, test-fitting is recommended before mounting tires or driving to ensure proper fitment; once tires are mounted or the vehicle has been driven on, returns may not be accepted.
