I saw a link once where a Insight owner had replace the mirrors with 2 small cameras to improve the drag and milage, anyone remember this and the link?
Are they any aftermarket hoods and tanklids in carbonfiber to decrease the wieght of the car?
Hi Alex; I am one person who has replaced the outside mirrors with a video camera. I mounted the color camera in the left tail light lens. There is a 5 inch color monitor on the far left side of my dashboard. It works great. I mainly did it for looks; I feel the Insight has rather large ungainly mirrors. At higher freeway speeds there is a small aero benefit, but not very much.
No aftermarket parts like you describe, afaik. The hood is aluminum and already very lightweight. The only "heavy" item may be the large amount of glass in the rear deck lid.
