Has anyone used the Easy Lift by Land Rover Passion? I'm looking in to lift options for my 07' RR and all I've found were Johnson Rods and this. Easy Lift says it has height settings of +70mm, +55mm, +35mm, Neutral, -20mm, and -30mm. Does anyone know the stock lowered and off-road heights are for comparison? I'm wondering it you could keep it in a lifted mode for everyday driving like having Johnson's Rods installed. Let me know if anyone has any experience with them....
