Lexcen Polycarb window info

[timbo]

Quite a bit I would imagine. Glass is heavy, a hatch with out glass weighs next to nothing and the rear glass in a coupe is probably 2/3's the size of hatch glass.

Density of glass: 2500 kg/m3
Density of Lexan: 1200 kg/m3

go to bunnings they sell big sheets of polycarbonate/lexon and just cut it ur self thats what im doing when i get a bit more cash, also agreed u dont want acrylic

[slydar]

its a worhty saving for sure.

also it lowers the CG of the car. as do a light weight bonnet etc. double bonus.

It would be worth it but not very legal. You could get away with side glass but not the rear, as previously stated it would need to be strapped in.

Mine has one window from bunnings sheet. Not sure what material as the previous owner did it when he had to smash the window to unlock the car.
But it looks like glass,doesnt scratch as bad as everyone says and is cool to bend for party tricks.

I have made a few 4mm ABS plastic ones for some race cars though. Not sure how they would go sitting in the sun for a whole day, but the plastic doesnt crack very easily.

would a plastics supplier be cheaper than bunnings?

matt: wow I am going to have to ask them about that

I asked our department of transport and they didn't have any problems with rear. But every state is different

I've got a lexan rear, the sun caused it to bow inward. After about a year or so when the UV/Sunlight permanently set it I took it out and flipped it around so it no longer was sunk in when sitting. Gets sucked in when driving (vacuum affect) with windows down though, but it pops back out as soon as I stop.

How is the rear mounted/braced?
