If your BMW Z3 window is discolored, darkened, cracked or the bead around the outside is separating you don't need a new top. You only need to replace the window to correct the problem. Fortunately BMW provided for their windows with a zipper system allowing it to be replaced without removing, replacing or disturbing the top itself. PLEASE INSURE YOUR WINDOW IS A ZIP IN BEFORE ORDERING. The old window is simply unzipped and removed and the replacement window is zipped in. This window is a zip-in window just like the original BMW window except it includes a higher quality trim on the outside edge that should outlast the original plastic trim that usually is the first component of the original tops to break down. It is Made in the USA using DOT approved .40 mil. plastic (same as BMW) that is higher in quality than the original window and only half the price. The size of my window is approximately 16 1/2" X 39 1/2" zipper to zipper if you wish to check. NOTE: EVERYTHING NEEDED FOR INSTALLATION IS INCLUDED WITH YOUR WINDOWThe Original window plastic can be easily scratched with a sharp object. This plastic is much tougher and resistant to scratching and won't easily be scratched and in addition it is more flexible, meaning that it should be more resistant to creasing and cracking. It is very resistant to "Memory" in that it will not retain folds from when the top is left down for extended periods. It always comes right back to original flatness when the top is opened. Also, the exterior trim that covers the edge of top not only covers all rough or frayed edges of the top but will last much longer and not deteriorate like BMW's plastic trim.I am often asked by people if they can replace the window themselves. The answer is an absolute "YES". You simply unzip the old window from inside and the new window zips in easily. Your window will include the zipper slider necessary to do the operation (zipping and unzipping). I don't want to over simplify the installation as it does take a little time and patience but anyone can do it. I do highly recommend you get someone to assist you (one inside the car and one outside just to keep things lined up) and it should take 1-2 hours at the most. I have had feedback that some have accomplished it in approximately 15-20 minutes but honestly this is the exception. It generally takes me about 45 minutes but I have done it a few times so I would count on 1 or 2 hours unless you are very quick and a handy person. I will include the simple to follow instructions with your order.There are cheaper copies and many overpriced similar items but I promise you none are any better quality or easier to install than this one. These have satisfied many Z3 owners all over the world and saved them money. This same window is on my wife's personal Z3. It comes with a 1 year replacement warranty against all defects or deterioration beyond normal wear. Don't waste your money on the overpriced BMW original window. This one will long outlast it for half the money. It is truly the best quality and best buy out there. This window is darker in a grey tint but it is only 40% tinted (allows 40% light to pass through). It is not the real real dark tint like you find on many cars today that you can't see through. Those are generally 5-15%. I will ship internationally for a small increase in shipping costs. Just click on International Shipping below. I try to ship as soon as possible after receiving an order. Thanks for your interest and best of luck with your BMW window replacement.HERE IS SOME FEEDBACK I HAVE RECEIVED RECENTLY THAT MAY HELP YOU IN YOUR DECISIONThanks David I was able to finish yesterday and it turned out great.I used a white pencil to mark a reference point.Then sniffing to the left approx.a quarter inch and zipped it in and window was completely smooth.Your replacement window fits like a glove I would highly recommend it.Also I feel in your design with the canvas overlap of canvas top is right on,and one more thing the price of the OEM replacement just under 400 bucks is just an example of greed.Thanks again David and good luck forward.Sent from my iPad. D.Allen PalmerRecently, I purchased a rear plastic window for my BMW Z-3 from you on E-BAY. To recount. It arrived on time with adequate email tracking. All items noted in your communications were included in the package, including detailed installation instructions.I decided to have a local auto upholsterer install the window as they were familiar with the car and the process. I just removed my car from storage and on last Tuesday 4-9-19 had your rear window installed. It took them an hour as they wanted to do a careful job. When I picked up my car I was thoroughly pleased with the outcome and appearance. Looked just like a new factory installation. This was so satisfying as it was a USA sourced product and it worked just as claimed.CONGRATS ON YOUR WORK AND PRODUCT.SylvesterHi David,Installation went great. Thanks for all the supporting installation instructions and feedback. David, I did the install took about 45 minuets and when very well thank you so much my aunt is very happy how it turned out thank you RyanThought I'd follow up and let you know that installation on the Z3 went great. Your installation document really helped out a lot. Definitely qualifies as a do-it-yourself project. No more opaque yellow back window! Thank you! - Gene Hi David, just to say thanks for your excellent service and helpful hints. I chose a warmish day with good light to start my refurb of my much loved Z3, we have been together for eighteen years!! And, like me, she needs a bit of TLC now!!!Your instructions were great, window came out like a breeze, and your replacement was a perfect fit, it took a few goes to get the zipper in the right place to start. On reflection I would not have tried to fit it in when there was any resistance when pulling the zipper round, as when the perfect starting place was found it zipped in, in seconds flat. I found a loop of cord threaded through the zipper end was the best and most flexible pulling method. Also it would definitely help to secure the zip ends when starting, one stitch would do it, maybe not super glue just in case it is not spot on.Also really liked the finishing flap, as my hood was fraying slightly. But be careful not to get the glue over the top, I used masking tape, and a little help from an indelible black marker pen, on the very small overspill spots.My friend, how helped me, and I are both ladies of a 'forever young'! age. So if we can do it anyone can!!!Thanks againShanDavid,I wanted to take a moment to send my appreciation for your BMW Z3 rear window replacement product. We have used it acouple times and our customers are thrilled with the product and the savings over the BMW price for the same part. Thanks again for your product and service David, have a good day. Regards,Brandin Tritex Corporation Hi David, We got the new window installed this afternoon. It took my son and me about one and a half hours. The Z3 body doesn't give you the interior room and angles that the 3 series offers, so it was tight. The car is in the garage now for the 24 hour waiting period and it looks great! Thanks much for providing an affordable solution that actually works!JimDavid,Just wanted to thank you for the new rear window, and the ease of installation. I have never replaced one, but after doing this one, it is no more than what we learned before going to school. Zip it in, glue it down. Took me less than one hour, doing it myself. It is a great product, a great result. Thanks again, JeremyDavid,Just wanted to let you know the window is working out great. It took my husband and son on try to get it in and it is great! The kit was complete and your instructions were very helpful. Thank you so much for helping to enjoy my BMW convertible again! Some of the stitching around the zipper on the top had already been coming apart. So before we installed the window, we stitched the zipper and top with your UV Resistant thread you sent extra! My son in law and I glued the trim around the window and your contact cement worked great. Thanks for everything.BrendaDavid, Thank You for this great product! We had the old window out in about 5 minutes and were working on lining up the new one shortly thereafter. It went in so easy that we actually took it out again, thinking that we must have missed a step. Instead of using the thread that came with the kit, I used 30 lb. test fishing line to sew the ends of the zippers closed. Once I wiped off our fingerprints with Novus glass cleaner, I would say the entire installation took about 45 minutes, not counting the gluing process. Also, tell your other customers not to panic if they see a few raised areas on the window once it is in. After the top is re-secured and the window has been in place a few hours, those slight ridges smooth right out. Also, instead of a butter knife, those angled nylon pry bars that are used for removing small interior parts are great for removing the old window without hurting your top. Thanks Again! Kelley Hi David,Thanks so much for all your helpful information with the updated installation instructions, as well as the video. I had used some cleaning product on my rear window that caused it to turn yellow in the sun and then when I finally did go to put the back window down, it cracked in 2 places. So, even though I wasn't planning on replacing the window since I will be purchasing a new car in the near future, I couldn't stand looking at it anymore. Plus, it will help me when I finally go to sell the car. Even though it is a 1997 model, I still get told what a nice car I have all the time. So, I was a lot embarrassed by the back window and decided to go online to find a replacement. For some reason, your ad caught my eye and rather than compare all the ads, I went with you because your ad really sounded honest and sincere to me. And since I am a woman, I can use all the instruction possible. Thank you for all your information, I'll need it I'm sure! GerigiannaSpringfiel, IlRichardAmarillo, TXThank you David My daughter and I fitted the window within the hour, waiting 10 minutes for the contact cement to dry was a bit longNo problem with alignment and very please with quality and finish' did what it said on the listing.Will recommend to others Kind Regards GenniferHouston. TX Hi David! We put the window in this weekend and it went really smoothly and it looks great! The video and the written instructions were clear and easy to follow. I found the comments and suggestions from the others you provided very helpful (excellent addition). Thank you so much for everything. Being a newbe at the online purchase thing I am really impressed with all the support and will not be so nervous next time!I hope they are all as straightforward and honest as you. Take care....and thanks again!SusanHi DavidJust to let you know that you were right.It arrived at 14.50 yesterday and was fitted by 16.30 perfectly,very pleased.So you have not lost a parcel yet,Thank you and thank you for your attention to detail, instructions and quick responses ,very refreshing.RegardsRogerDavid, Finally got around to installing the rear window. A little tricky but, with the help of a friend we got it done. It came out good the first time and looks nice. My only suggestion would be to enlarging the window trim as mine fit very tightly at the bottom corners and wants to curl up due to tightness. The contact cement provided worked well as I let it dry for a couple days in the garage to be safe. Overall I'm very satisfied with it. Thanks for all the help and being so responsive with questions. Thanks, DaveThat was remarkably easy. I used two helpers. One on each side of the car. Once the old window was out. I placed it on top of the new one and marked the zipper start location with a piece of chalk. It took a total of 11 minutes to get the old window out and the new one installed not counting the time to glue the trim down. This has been the easiest project I have tackled on my M3 to date. Thank you again. JohnLyman, SCHi David,I just wanted to quickly write you a big thanks for a great product mate. It took us half an hour to get it on after realising we had it upside down. The realisation came when the zipper wasn't feeding in properly. Not very bright at times. However, once we inverted the wonderful product you supplied us, it was on in 15 minutes. Thanks again mate and all the best. RegardsAlexArtarmon, NSW 2064hi david, sure have appreciated ll of your emails and assistance however it really did install easy and without complications. I would be glad to give/refer anybody who needs one your name . Also, I left you a very positive review! Thanks , window in, love our nice new window! LauraMosta, N/A MaltaWow, what help from you and what an easy installation. Much easier that I imagined. Looks great on and I can’t say enough positive. Ebay doesn’t give us enough room.FlorintinoKeller, TXHI, Went in fine. Took two guys about 30 minutes 1998 328IC. Rear window removal was about 5 minutes and the next one would take 2. The two complications we had was no lock on the zipper so as you started it would tend to unzip behind your progress. After the second time we put a little pinch clamp on it. Thanks for the follow up emails.Cheers,JaredSydney, AUSDavid,I was able to install my new Z3 window today and it went very well thanks to all the info you sent. It looks great. Thanks!!
