We know you want to put your Civic on the floor, it just looks better we get it. The Crash Bar is meant to be insurance to help save your oil pan. It sits approximate 3/4" lower than the oil pan and will now be the primary piece taking the abuse from daily driving. The idea here is that any obstructions you may face in the road will first hit the crash bar and saving the oil pan.
We've seen too many 8th and 9th Civics sitting on the side of the road with smashed and cracked oil pans and a puddle of oil surrounding the front end. Its a sad sight and even worse to deal with. Changing the oil pan isn't a simple job requiring dropping the subframe and a new alignment. That is best case scenario, assuming you caught it quick enough before the motor was starved of oil.
