Description
RS-R Down Sus Lowering Springs give 2014-2020 Lexus IS250/300/350 AWD (IS250/GSE36) a vehicle-specific way to reduce ride height while retaining the factory-style damper and spring layout. This is a straightforward option for owners who want a cleaner stance without the added adjustment and complexity of a full coilover system.
Why Choose RS-R Down Sus?
Down Sus is RS-R's standard lowering-spring line, developed around each vehicle's factory suspension geometry, damper behavior, spring rate and target ride height. It is the sensible choice when the goal is a cleaner stance and a more tied-down feel without replacing the complete damper assembly.

Before Ordering
Lowering springs are fixed-height components. Final ride height can vary with vehicle condition, factory options, mileage and load, so published drop figures should be treated as approximate. This listing is application-specific to the stated drivetrain/trim (AWD); verify that detail rather than ordering by model year alone.
