RS-R Lowering Springs - Lexus IS300 / IS350 (XE30) - Down / Super Down (2021+)
RS-R lowering springs for the Lexus IS300 / IS350 (XE30) reduce the wheel-arch gap with a drop tuned to work with the factory dampers and suspension geometry. Down springs give a mild drop while Super Down springs sit lower. Approximate drop: Down 25-30mm front / 25-30mm rear; Super Down 45-50mm front / 40-45mm rear.
Note: drop figures are approximate and vary with vehicle condition and options. A wheel alignment is required after fitting. These springs suit rear-wheel-drive models; the IS300h hybrid is not listed by RS-R. The Super Down set includes replacement front bump rubbers. Installation by a professional is recommended.
What's Included
- Set of 4 lowering springs (2 front / 2 rear)
- Super Down only: 2 replacement front bump rubbers
