Product Details
These RS-R Super-i coilovers fit the 2010-2015 Lexus RX350 FWD (GGL10W).
RS-R Super-i coilovers for the 2010-2015 Lexus RX350 FWD (GGL10W) are the top of the iSHOCK line — hand-assembled in Japan to the tightest tolerances, with premium valving components and pillowball uppers. Reserved for flagship chassis where the Best-i Active cannot be used, Super-i is RS-R’s most expensive coilover and the one they ship to their own demo cars. Rare in the US market; flown in from Osaka on order.
Super-i is RS-R’s hand-assembled top-tier coilover — the same monotube architecture as the rest of the iSHOCK family, built to the tightest tolerances with premium valving components. Reserved for flagship chassis like the Lexus LC500 and select applications where the Best-i Active cannot be used. Rare in the US market, delivered from Japan by air freight.
