The RS-R Basic-i Active Coilovers for the 2013-2020 Lexus GS350 F-Sport AWD (GRL15) can be used with the factory AVS system. AVS system does not function on current aftermarket shocks and coilovers. But the i☆SHOCK Active series retains these factory controls. Now the factory actuator can be used on an aftermarket coilover so the dampening and control systems still function.
