I had thought about this before and had recently saw the weigth reduction post (which I L<3VE) and I was curious as to why no one has made this for production? It sounds like there were a few made or maybe just one made. It cant be that hard to do and I know I would certainly be intrested in it. I plan on making my own with plexiglass over next winter if no one comes out with a replacement. Any ideas/comments welcome

 

because it might not be street legal. the glass roof is a structural part of the car just like the windshield.

i belive kaminari makes a carbon fiber roof for race purposes.

 

Yeah, Kaminari makes one, however I don't think they keep them stocked & they're made when ordered.

 

They make a CF one and a fiberglass one. They aren't cheap - but they do shed a lot of weight from the top of the car to lower the center of gravity.

 

hmmmmmm....intresting....I dont really mind it not being street legal my car isnt too legal lol...but ill have to check it out...thanks guys

 

Yea, like the OP said, I've always wondered too. I suppose because most DD use their sunroof.

I'm sure if it were affordable, ppl like AutoX or SCCA would want to have some extra benefit in center of gravity/lost weight. The common replacements would be better than glass- CF, fiberglass, aluminum.

I don't get how glass can be a structural requirement. It essential floats on top of a metal frame and busts into tiny pieces when struck. Now, if it's because some other material would be unsafe, like it splinters or something, I get it.

 

yeah, i know that the fixed pieces of glass can clearly be part of the structural integrity of the car, but i've always wondered why one can't simply replace them with a light weight glass, or perhaps some high quality air craft aluminum or something for some weight savings/lowering the center of gravity in the car.
