    Windshield: OEM vs. Aftermarket

    Though there are many threads on windshield replacement, I have not found a discussion on OEM vs. Aftermarket.

    Has anyone had experience with OEM windshield vs. an aftermarket product? I have the rain sensor but not the phone antenna. I have found that you can get OEM glass not through Porsche but is the same brand which I was told was Pinkington Siglar glass. Does anyone have info on this?

    I have started doing some research around town (San Diego). Porsche dealership wants $950 to use OEM. One glass shop can do aftermarket glass for $500, another glass shop can get OEM glass just not through Porshe installed for $594.

    If anyone has experience in San Diego with any shops, your thoughts would be appreciated.

    Re: Windshield: OEM vs. Aftermarket

    Sekurit makes OEM Porsche windshields and the higher prices are due to engineering, quality, import duties, etc. Sekurit has won a few patent infringement cases against other glass manufacturers for copying and stealing some of their proprietary designs and tech.

    I joked with a fiend that Pilkington glass is called Pilkington because that is the sound you hear as it breaks the first time even the smallest pebble is thrown up from another vehicle and makes contact. I'm sure they make some quality products but when my insurance co replaced the glass in the Boxster they demanded the lower cost Pilkington glass and it lasted less than 30 days. The second time around I had a pretty good case to demand OEM and never had another issue. Coincidence? Perhaps.

    My wife's Honda had 3 Pilkington windshields before we convinced the insurance company they were losing more money than they were saving with cheap replacements. Replacement OEM Honda windshield was still on the car when we traded it in. Draw your won conclusions.

    Rain Sensor is not an issue as it is co-located with your rear view mirror mount. I'm not in San Diego, though I wish I was, but an independent shop ordered glass for my '07 CS and it seems to be fine. I took a look at the glass before the installer put it in and it had a sticker on it that was marked 987 Boxster. Your $594 estimate sounds very good to me. I believe mine was closer to $700. I know the OEM glass has a coating on it similar to Rain-X. I've only driven the car a couple of times in the rain but it seemed to bead up nicely.

    I have not received my cayman yet still on a boat should be at port on the 16th of this month I was told. I am not sure if this answers your question however, in terms of OEM vs aftermarket glass I have always been told request OEM so you get the same quality because if you get aftermarket you can end up with chinese glass, not sure if that is a real type of glass or just a industry term for cheap glass. I always get a zero deductible on my car insurance for glass. The cost to have a zero deductible is minamal I think I pay $100 a year. Insurance has always allowed OEM glass and insurance has new gone up. I am a salesman so on the road a lot with a lot of broken windows at least two a year.

    My windscreen dealer said Porsche normally use windshields from Saint Gobain (here in the UK). He said the proof is in the very small Saint Gobain stamp/print on windshield near where the vin number is located. I checked into this the same day...he was spot on! Costs around 300-350 here.

    In the US Saint Gobain = Sekurit and sometimes the glass has Saint Gobain Sekurit printed on it others I have seen read only Sekurit.

    Re: Windshield: OEM vs. Aftermarket

    OEM vs. Aftermarket is always a touchy issue. I'm a firm believer in you get what you pay for. With with that said I've also had some personal experience from my job with OEM vs Aftermarket marketing. I work for a bearing company that makes all kinds of product. People are right about rebadging products, we ship out bearings to CAT, Deer, CASE NH, etc with their boxes, serial numbers, and part numbers. We also sell the same bearings with our boxes, serial number and part numbers at the same time.

    If you know for sure that the OEM part comes from a direct supplier then I'm sure Porsche will mark up their OEM price probably more than 50% as compared to just getting it straight from supplier. Our products if bought from CAT or other companies has direct replacements will cost 50% more if you had found the same exact replacements from us through distributors such as Motion industries and so forth.

    But.. if you buy a product from another company that is copying another product, 99.99% of the time its inferior. That comes from experience too. We are great in certain bearings and suck at other types, we rather just reverse engineer them. 99.99% of the time we get one thing or another wrong!!!. I work as a design engineer and specifically started out in testing. Our reverse engineered products usually have 50% of the life or less of the REAL product.

    Best way is to go OEM!!!

    Re: Windshield: OEM vs. Aftermarket

    I recently had my windshield replaced and the installer told the dealer he was going to use an aftermarket product. The dealer called me and advised me of the situation. I ended up with a factory windshield thanks to my insurance agents intervention.

    I have not tried an aftermarket Porsche windshield.

    No wonder..Rain X never reacted well with my windshield and made my wiper wipes less clear

    Re: Windshield: OEM vs. Aftermarket

    My wife's old Mercedes had a cracked windshield. I call my insurance company and they sent a window replacement company to put in a new one. The replacement company did a c%$p job so I complained to my insurance company and complained. My insurance company told me to call Mercedes. Mercedes sent someone out. It was the same company that came the first time.

    I, too, would stay away from aftermarket windshield considering my experience with replacement of glass on a BMW 330. Contract installer tried to pull a fast one on my auto insurance carrier and install aftermarket which I am told was not of OEM quality, whatever that means. I agree that this is one of those situations where "you get what you (or insurance) pay for".

    Re: Windshield: OEM vs. Aftermarket

    I had a butcher job on a Vette with a dealer paid but vendor supplied windshield replacement.

    I had a BMW windshield replaced on the 530i I used to have by the dealer with OEM and the install was excellent.

    I stick with the dealer from now on - since even if it is butchered, they are easier to get satisfaction from than the windshield shops (IMHO).

    Exclamation Re: Windshield: OEM vs. Aftermarket

    UPDATE:

    I decided to go through my insurance company (USAA) as they have always been great with everything they do. I also decided OEM was the way to go. USAA approved the use of OEM glass. They have a contract with Safelite Auto Glass which is a national company. I've read good and bad things about them. Mostly good stuff for the branch in San Diego, so hopefully it goes well.

    The Porsche dealership should have the glass in on Monday, so maybe an install on Tuesday. Keep your fingers crossed for me, hopefully the installer knows what he is doing. I'll try and take some pics during the process.

    Thanks to all for your inputs.

    Re: Windshield: OEM vs. Aftermarket

    One last thought on this issue. If the installer scratches the paint through to the base metal under the seal and they do not repair the damage you may end up with corrosion. I've had it happen to me before. Many manufacturers use a plain carbon steel product for the roof. It saves some money as there is very little potential for corrosion on the roof and the surface quality for a 2B cold rolled carbon roof is excellent.

    Re: Windshield: OEM vs. Aftermarket

    Good luck with the windshield install. For what its worth, I recently had my Cayman windshield replaced (also went with USAA/Safelite) and the glass that Safelite was using for porsches without specifically requesting any certain brand was Saint - Gobain Sekurit (made in the Czech Republic). So far I've been very happy with the glass and the install was excellent. Hopefully you'll get a good tech to do the work. I also had Safelite come to my house for the install - easier to keep an eye on things .

    Re: Windshield: OEM vs. Aftermarket

    UPDATE:

    Had the install done last week by Safelite Autoglass out of their Carlsbad store. Gus Faudoa was the technician they sent out. He was very profession and actually had a lot of experience with Porsche's (or so he said).

    Anyway, he was true to his word, the install went perfectly and I have no issues. He used what he said was a new system with pulley's and a wire cable to remove the old windshield. The pulley's would attach to the inside of the windshield with suction cups. The wire was shoved between the gasket and the cars body around the edge of the windshield. The pulley system was then used to pull the wire through to the inside thus breaking the seal and adhesive of the glass to the car. Very smart system.

    Thanks to all for your help. Sorry, forgot my camera, thus no pictures.

    I have very similar experience, but rather in the telecommunications industry, and I agree; unless you KNOW the source and pedigree of the aftermarket part, OEM is the best way to go.

    This is the point I was going to make.

    Don't confuse "OEM" windshield with "Having it installed at the dealership."

    The dealership has glass installers show up and they mark up the whole thing.

    You can have the same guys come to your house with the same glass and do the same job.

    Send a few hundred extra dollars to the dealer if it makes you happy, but you will not get a better job done.

    The guy who installed my windshield does all the Porsches at the dealership. He told me that there wasn't any difference in the glass but the OEM fits better and is easier to install. I went with OEM.
