perspex/lexan windows for GT3....
Discussion
has anyone done this to a non RS car?
drove mates RS recently in north wales back to back with mine and I love the sound it makes from the rear with the lexan window and less deadening.
noticed the single mass flywheel too and how much quicker it revs up that normal GT3 with dual mass. the RS feels more alive and figidty on normal roads....not always a good thing in the UK with the cambers and dodgy roads.
got a mate who runs a business making polycarb windows for all cars and he might want a guinea pig as has no 996 templates.
good idea or not? would certainly remove some weight from the car if I done the rear window and rear sides. would certainly help with hearing that lovely engine and the noise at top end.
I know they can scratch if not treated with care as have had them on a few track BMWs.
would keep the OEM glass for futures in case it ever needed to go back to normal or be sold on.
it would only be rear window on my gt3 and the rear sides so they are all fixed in. car has air con and would keep glass leccy front windows.
I know the 996 and 7 RS has the rear lexan window. was it the gen 2 997 RS that had the side windows done as well?

The rear window isn't flat. It's simple enough to cut the shape out but it won't stay in place in the opening using the factory seals etc.
You need to bond it in place without the seal and trim used with the OEM windows, while weighing it down to help it keep the shape as the adhesive sets. It can be done cheaply but it also looks as cheap as it costs. Its tough to keep them water tight this way too.
The side windows can be done more successfully since these are flat.
The side windows have multiple fixing points that cannot be replicated without sacrificing a set of OEM windows (either glass or lexan) to obtain them. There are threaded bushings etc bonded to the window itself.
With the windows being flat, its easy enough to bond them in place using adhesive (as an alternative) without it looking cheap as with the rear window. Weight savings on the side windows are not huge tbh.
Again, keeping them completely water tight when bonding is difficult since they cannot press against the factory seal in the way they do using the regular fixings. Depending on where you live and how you use the car, that may not be that helpful. It would be compounded when there is trim inside to soak up the water I would imagine.
If I was handing out advice, I would say that you should just use the OEM rear window if you want to do this. The DIY windows aren't worth the savings in cost there. The sides could be worth a punt for the DIY attempt if the cost was low enough that no one will be upset if they end up heading to the skip.
