ATTN: ISC polycarbonate hatch owners

How is the fit/finish? Does it leak in the wet? Are you satisfied overall with the product? I'm looking at the hatch and quarter windows for my 85. Any opinions are appreciated.

Thanks

I wouldn't expect much for sealing since these are racing parts. Although the basic design of the FB should allow for some use of butyl rubber to install the side windows and the stock seal for the hatch goes right against the glass, it should be fine against the plastic too.

That's what I am thinking. Probably just depends on fit/finish, and that is what I am looking to find out (how it fits).

Thanks

I have 2 of them but on race cars, so they don't sit out and get wet. Expect to put about 6 dzus fasterners to hold it down tight. If you push it up tight against the seal it'll be fine.

Can you use the stock latch and hinges with the plastic hatch?

I have one on my EP car - works fine. Of course, it appears that you want to put one on a street car for some reason, which would likely be stupid. It's flexible and buffets and leaks air at high speeds, it's noisy, it will just bend at the edges if someone wants to break into to your car, and under normal everyday street use it should get scratched, hazy and basically unusable in about six months. But other than that, by all means put it on your street car.

What he said. Lexan windows are not meant for street cars. It will get scratched and won't seal very well. You won't be happy with the day to day functionality of it - it will be noisy, leak air and water, and will not last. To secure it properly for street use, you will not be able to use the stock latch, and will need to install alternate fasteners. The reason race cars use it is primarily for weight reduction and / or to relocate weight from a higher CG to a lower CG.

I was considering this for my EM auto-x car (5.0 V8), which is still street legal. It will not be a daily driven car, but driven and parked outside at times. That is why I was curious about it. ISC doesn't give the best of descriptions on their site, so I didn't know how it mounted, or how functional it was. I know lexan will scratch easily and stuff, but wasn't sure how bad it would be on a rear window (I definitley won't do the front). My car needs to lose as much weight as possible, as I have quite a bit to go before reaching minimum race weight. I posted here as it is a 1st gen part, that's why it is not in the race section. Don't jump the gun and think I am some punk kid trying to rice out my car. This is primarily a car that will be used for competition, just was curious about the functionality.

This makes better sense. You can then make all sorts of functional compromises in order to accomplish lightness. My EP car has a home fabbed rear window - the original builder bought a piece of Lexan at Home Depot, and used a heat gun to mold it to the shape of the stock rear, then trimmed to fit. Doesn't fit all that well, but is adequate for the purpose.

You could almost go full race prep - get rid of the stock dash and interior, side windows, etc. Lots of lightening opportunities.

Yeah, I'm just trying to figure out how far I want to go. I'd like to keep the car street legal, as it will be a fun car to drive. I know it will never be a "national" car, but would like to enjoy it.

Just as a guide - you get much better responses about race pars for race applications when posting in the race section (imagine that!).

OK - since yours was a more serious question that the typical "lets put a race body on my street car" thing, here is the scoop:

Generally, us racers are trying to get the weight down as low as possible rather than having all that weight high in the car. The lexan that ISC sells is definitely for race purposes, and probably thinner than you are imagining it. It flexes and "booms" at high speed, becasue it is only meant basically as an aerodynamic closure for us. Mive has two steel straps that mount under the stock hinges and run lengthwise down the window. They overlap onto the body at the bottom of the window, and I have drilled the straps and body and installed Dzus fasteners to hold it all closed tightly while on track.

Since the window is very "flat" it will have all kinds of things that fall on it on the road that need to be cleaned off. Lexan accumulates scratches pretty quickly if not taken care of so under the rigors of everyday use it will become translucent in short order - which is not good enough or safe driving.

Good Luck with your project.
