Hey gang
I have been floating through the forum for a while and am looking to make
some mods to my wife’s 2004 Honda civic 4door.

She travels 114 miles round trip a day.

I am hoping to find someone that has worked one before and would be willing to share what they have done but all suggestions would be appreciated.

I am thinking a full grill block, a front air dam, side skirts, solid hub caps, rear wheel covers and take off any antenna as well as try to move the mirrors in the car.

I am concerned with the grill block and the air dam as will these prevent the radiator from doing its job? From experience how much should I expect to pick up in terms of FE?
Thanks
