Tom,
I had a set on my car. The look was right for the car (my opinion) but the rear visibility was poor on the drivers side and non-existant on the passenger side. So I took them off and sold them. Someone makes a 1 or 2" extension that makes the visiblility much better. I think it's Kirk Evans. One of the local cars is an Amerisport GT5S and it has the extensions. Here's a picture of it.
