I have been looking over on EM and other sources for Kammbacks and have decided to try and see what I can do for my FIT to make it more FITTING. So I mocked up one this afternoon with some cardboard and tape to see what shape I could get with it. this is what I came up with so far. I left a 2 inch or so flap on the main part and may fill in the side triangles (as seen in the left and right pictures if I want to keep the length. Right Left I think I have the line/curve from the roof carrying on through so I should have good air flow. Also wanted to use the lines of the lights to do the sides to make it look like it belonged. Back view Shows the tapering From inside Even with the extra 2 inches it doesn't intrude to much into the line of sight from the rearview mirror. The third light would be blocked unless I was able to get some clear material (which I would prefer). I also have been thinking about completing the kammring on the back of the hatch to help smooth out the whole back end and decrease the overall wake size. from the side. (there are some gaps in it but this was just to see what it would look like. I might need a little more length on the tabs. From the side with a little angle. Thoughts, comments?
