Product Details

RS-R Super Down Sus springs for the 2016+ Lexus RC300 (GSC15L) deliver an aggressive, tucked stance without giving up daily drivability. The progressive-rate coils close up the fender gap, drop the center of gravity and tighten body roll through corners, while RS-R’s vehicle-specific rate tuning keeps the ride compliant on rough pavement.

The Super Down Sus takes RS-R’s progressive-rate Down Sus platform and dials in a more aggressive drop for drivers who want real stance without jumping to a full coilover. Every set is cold-wound in Osaka, Japan to a vehicle-specific rate so the car stays daily-capable at the lower ride height. Covered by RS-R’s 3-year / 50,000 km spring-fatigue warranty.
