This is what the Abflug 918 kit looks like, will cost you about 20k for everything including the lights:
For 20K i think this kit is quite overpriced I am looking for some head and tail lights though I think I am going to fiberglass my own and use a lexan plastic or similar plastic sheet and heat form it into shape for the lens there really quite simple lights the body is just fiberglass with 2 projector lamps in it easily found for $100 for 2 lamps on eBay need one for low beam and one for high beam so $200 total for the lamps and they come with the whole transformer kit then a plastic lens over the top, this I think could be sealed on with a auto gasket glue like silastik.
For 20K though you'd be hoping the composite process has been that top notch that the glass is extremely light and still wont crack under pressure.
I remember when I was working at Mariah Hovercraft I was manufacturing hovercraft rear stabilizer wings we found by using a foam core and 2 single sheets of cloth we could make a whole wing that weighed just 2kg and was almost twice as strong as the old wings made of fiberglass weaved mat with no core and weighed around 6kg!
Thats the difference between a composite bumper made by Mclaren compared to an aftermarket body kit shop (plain rubbish kits that crack) they weigh more than the plastic bumpers that they replaced and I'm sure they don't make
the Mitsubishi lancers there commonly fitted to have anymore down force :P
