True, although I think the front is kept for its structural properties too.

P/P windows are riveted/bolted onto the car and makeshift seals are added, but they wont fit as snug as standard windows, so will possibly leak and are easy to lift out and climb into the car, hence less secure.

Waste of money on a road car, better off getting rid of a heavy ICE install instead.

exactly what i was going to say stark, front are a british standard and have to stay the same, plus will scratch too easily.

And they can be cut easier than glass just smashing

Polycarbonate or Perspex windows are 100% road legal on all side and rear windows. Polycarbonate is slightly better in that it wont fog up unlike Perspex, but is it a bit more expensive.

Your front windscreen MUST remain standard laminate though.

To be honest though, for all the weight saving you'll gain its not worth it for a road car. Poly/Perspex windows are much less secure than the standard windows, meaning you couldnt leave it anywhere for a medium-long period of time.

i should also imagine it depends on how clear they are depending on the brand

Surely wudnt be legal for the windscreen tho? very dangerous to bang into summat rather than go thru it :S

if i remember correctly i read somewhere that they are legal .

90% sure , would be better security too

ploycarbonate windows are generally coated to help prevent scratching...

and as far as i am aware its only illegal to have the front screen ploycarb

Tint film scratches easily aswell

when i get them i will be getting the rears tinted which ll minimise the scratching. And get protective clear film on the fronts

poly carb are quite easy to scratch yes. but about 30% of the weight

Yea iaz thats the reason windscreens are illegal, i heard they are legal although mates dad has 2 cossies, one is a rally car and has plastic windows but hardly ever comes out on the roads he said mainly because of the windows not glass but im unsure :o wouldnt bother me legal or not :lol:

only prob i wud c with poly windows wud be they mas scratch easy?!?! just summit to think about mate! iaz

ahh ok i seee :thumbs:

normal windows are glass and heavy, polycarbonate are plastic based i think and are lighter and dont smash.

whats th diff between norm windows and polycarbonate?

ok 1-1 any one else or do you know for certain that they are legal?

yeah they are road legal.

as far as I know...

no there not road-legal

looking to replace all windows except the windscreen!
Had a quote of £190 all in for all the replacement windows, just need to know if its gona be road legal before i order them.

Cheers:P
