The RS-R Down Sus Lowering Springs are engineered for the 2021+ Lexus IS 300 and IS 350 RWD models, offering a balance of performance and comfort. These springs are designed to reduce the fender-to-wheel gap by approximately -25mm to -30mm (-1.0in to -1.2in) on both the front and rear. With a front spring rate of 5.48kg/mm and a rear spring rate of 8.16kg/mm, these springs are developed with consideration for the factory suspension geometry and shock dampening. This ensures that the springs work harmoniously with your vehicle's existing setup for enhanced handling without sacrificing ride quality.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
