What do you guys think of a Kammback shaped roof on a sedan (that of course has a trunk)?

I think about it all the time and one day will get off my lazy a$$ and build one for my car. In all my thinking about it though, I have determined you need to do it to the template or not at all. Chances are whoever designed your car has balanced out the air going over the back of your car to minimize any kind of vortex creation, if you try to do something half baked, you'll ruin that and end up with a worse Cd.

Here's a photoshop version of what I wanna do.

What kinda car ya got??

Hah, awesome this came up, I've been contemplating the same thing for my 09

I definitely agree with Chazinmt said, it will absolutely have to go with the template or it can majorly hurt your existing cd

I'm off day after tomorrow, I smell a fun project coming if the weather is nice...
