Well...
The greatest opportunity for improvement is at the rear but that doesn't mean front-end work is a waste of time or that benefit there is fake as opposed to "real".

70+ sqare inches of awful up front is worth improving IMO (5x7 headlight = 35 sq in x 2 = 70 plus all the gaps and edges nearby). Every bit of air you help get over/around the front is that much more opportunity for improvement in the rear.
