RS-R Down Sus Lowering Springs for 2006-2013 Lexus IS350 (GSE20/GSE21)
$83.70 $279.00
RS-R Down Sus lowering springs for the 2006-2013 Lexus IS350 (GSE20/GSE21) drop the car into a cleaner, more purposeful stance while tightening body roll and sharpening turn-in on everyday roads. Each set is engineered specifically for this IS350 chassis, so drop, spring rate and factory damper tune stay in balance — the car sits where you want it and still drives like a daily.
Racing Studio-R built its first suspension in Osaka in 1972 and has been refining the Down Sus spring for more than fifty years. Each set is progressive-rate, cold-wound and heat-treated in-house in Japan, then matched to the factory shock valving and ride-height target of the specific chassis it bolts onto. Backed by RS-R’s 3-year / 50,000 km fatigue warranty.
