RS-R Down Sus Lowering Springs - Lexus IS300 / IS350 RWD GSE31 2021+

Description

RS*R Down Spring was designed to provide the the best combination of looks, performance, and ride quality. These springs bring the car 1-2 inches lower than factory specs for optimal center of gravity with a moderate increase in spring rate for better cornering an manuverbility. RS*R uses a technique called high frequency induction heating to create the springs which is uniquely found in RS*R factory. This is different from the usual method of making springs, which is cold winding, like winding a metal rod into a spring w/o added heat.
