With reference to the above subject, I have installed "Suspension Rogerab" in my car on 12th July 2018. I am giving this feedback after having long journey of almost 1700-2000 km and found that it is working as per my exceptions. I could feel the difference in driving on highway and also on the internal road which is having number of speed breaker of various size. Basically it is fearless driving particularly on internal road where you have the fear of touching your car on the speed breakers.
