Are you sure the aftermarket ones would seal perfectly?

Legality aside, (be sure before you jump),visibility would be decreased by them, a reason to avoid them.

To me, they are a "Ricer" look on any vehicle. Individuality can be better expressed through the typical stereo or wheel upgrades, if you want them.
