View Full Version : polycarbonate windows ?
anyone using them on a daily driver/occassional track whore
(r26r owner even :)) ??
few general questions about them just out of interest really
1-can they be made to function like the original glass items do ?
i.e : could they be mounted up to the window winder mech (manual or electric ) to wind up and down ? even though i have not inspected them in
flesh i cant see why this cant be done unless i am missing the point big style here ??
2-are there any downsides to using them especially on a daily driver ?
i.e : do they scratch easily making it a bitch to see through side windows?
do they fail the mot test etc ?
3-whats the rough amount of weight saved using them on a clio ?
i am talking weight saved by removal of glass only not winder mechanisms or other shizzle :wink:
excluding the windscreen of course .
4-what about winter time with poly stuff ? especially the rear screen ?
is there a solution for defrosting /demisting similar to heated rear screen??
1..yes they can but missing the point as the electrics are the heaviest part.. maybe with manuals..
2..not really..except they don't open on the front.
3..about 5kgs iirc.
4..not that i'm aware of.
i got them on the rear 3 of my 5. if u use them with winders they scratch to buggery and u cant see.
but the rear 3 are fine i would say they are half the weight of glass.
on my tail gate i removed all the crap wipers ect and fitted poly and took the grinder to any un essential metal bits it went from 14kgs to 7
now my power to weight is 200bhp per ton [better than most scoobys] love it

After washing the car a few times the polycarbonate will be scratched. I would never fit them to a road car.
3..about 5kgs iirc.
.
only 5 kgs for the lot ?? :shock: :shock:
fook that , i could easily loose that by shaving my testicles :D
yeah about a kilo a window...maybe two for the rear but if you remove rear wipers electric window motors wiring switches etc might be closer to 10kg for the lot..

You can save more with 2mm polycarbs, but they arent fia legal, as the minimum thickness is 4mm. So you remove 2mm glass and end up fitting 4mmm polycarbs, so you save very little weight.
Better off converting to a cabriolet ifyou want to save weight.
dont scratch up as much as you'd think despite washing if your gentle and use a proper wash mitt and 2 bucket to eliminate grit etc. despite what the 'doctor' says, also they pc back up again a treat.
no discoulouration as yet either despite the car being stored outside in sun etc
wouldn't use winders etc, they will scratch up badly in minutes
pass mot no problem
they do leak a bit of water on the fronts but it all goes into the door and out the drain holes, not into the car itself
its a lot of weight saved with all the gubbins removed aswell
no way to demist rear screen quickly but tbh car doesnt get used much in winter and when it does i just leave it to heat up for a few mins and it clear on internal heaters
it sounds too much of a hassle to loose little weight imo .
i will just shave da ballzz instead :D

Why not convert to an auto box and become and amputee?

i think it is safe to say there is no way that clio glass is 2mm. its at least 3mm but im pretty sure its 4mm, the same thickness as the polycarbonate windows i replaced it with.
polycarbs weigh half the weight of glass, plus if fixed means a huge saving of all the electric window regulators and window tracking etc.
yeah polycarb does scratch easy, but if your careful its not too bad. glass polish works well to remove the light scratches anyway.

hahaha :lol:
so the point in this topic was to save weight..... u argue a cabs is lighter and the only example is a car that didnt have them as standard and when fitted was made by a company probably trying to save weight??? so back to what i said... cabs generally are lighter me old m8 :wink:

Modern day convertables are usually heavier due to all the reinforcement / saftey requirements and fancy roof mechanisms.
yeah that was why i stated they are heavier. was just a reply to a silly comment made about cabs bein lighter.
