172 cup glass transplant to a non cup

[leew88]

i have a donor cup and a non cup, im keeping the propper one,is it worth the hassle,anyone tried?

 

[Ryanj]

IIRC theres absolutely no difference in the glass between cup and non cup...

 

[levaz]

cup glass is supposedly lighter / thinner.
probably a shitty job though, hate doing windows.

 

[Martin.]

I thought it was thinner!?

 

[peanuthead]

It is thinner. But really what's the point? For a road car you won't notice the difference. if it's a race car and you want to save as much weight as possible, go for poly windows

 

[leew88]

waste of time then,shame as the drivers door on mine will have to come apart at some point the drivers door only locks from the key and since il have the parts - i think too much lol

I could be interested in the cup glass all round depending where you are?

 

[Goodj]

go take a dump before you drive the car and it'll have 500% more impact to the weight of the vehicle.

it's your car, do what you want.
it'll make little difference on a road car, but if you plan on tracking it or pushing more performance from it, losing as much weight as possible is always a good starting point.

I've heard it all now.

Lol.

 

[leew88]

it was just a brainwave-once the aircons bypassed this week (assuming i can find some spacers suitable) im pretty much stumped for any gains without going cams or turbo route

im in durham

5kg lighter glass on the cup vs non cup. Quite a big difference when i checked between the sets i have in the garage.

Amazed its that much!

Glass weight is very high up too, which is what effects handling the most, 5kg up there is worth double that lower down.

(although I still wouldnt bother personally on a road car, and would go poly for a track car I was trying to make light)

 

[EVOgone]

Made me question weather to have polycarbs but did in the end.

 

[Jamie86]

Ideal for say a restricted race series mind

 

[Tony Hunter]

I'll be checking

I'll be checking

What that they are production glass windows from a Renaultsport Clio

 

[Tony Hunter]

I'll think of something.

 

[leew88]

which windows did you weigh for the 5kg difference? i hope not 6 or i might be onto something lol
