Step 3: Test and make necessary adjustments
After the new convertible top is installed, it’s important to test it for proper functionality. Raise and lower the top several times to ensure it moves smoothly and without any obstructions. If you notice any issues, such as the top getting caught or not fully closing, make the necessary adjustments. This may involve tightening or loosening the bolts or adjusting the tension on the frame.
By following this guide, you can successfully replace the convertible top on your 1987 BMW 325i. Remember to take your time, be patient, and seek the help of a professional if needed. With a new convertible top, your classic BMW will be ready to hit the road in style!
What is a convertible top?
A convertible top, also known as a soft top or roof, is a type of vehicle roof that can be folded or removed to allow for an open-air driving experience. Unlike traditional hardtop roofs, convertible tops are made of fabric or vinyl materials that can be easily folded or retracted.
Convertibles have been a popular choice among car enthusiasts for many years, as they offer the freedom and thrill of driving with the wind in your hair. The convertible top plays a crucial role in the overall design and functionality of a convertible car.
Types of convertible tops
There are several types of convertible tops, including:
- Folding soft tops: These are the most common type of convertible tops, which fold down into a well behind the rear seats or into the trunk of the car.
- Retractable hardtops: These convertible tops are made of metal panels that automatically retract and fold into the trunk with the push of a button.
- Targa tops: Targa tops have removable roof panels, typically made of glass or reinforced plastic, leaving a fixed roof bar in the center of the car.
Benefits and considerations
Convertible tops provide several benefits, including:
- Open-air driving experience: Convertible tops allow you to experience the thrill of driving with the wind in your hair and a clear view of the sky.
- Versatility: Convertible tops can be folded or removed, allowing you to transform your car into a different driving experience depending on the weather or your mood.
- Style: Convertible tops add a sense of style and sophistication to a vehicle, making it stand out on the road.
However, there are also a few considerations when it comes to convertible tops:
- Weather protection: While convertible tops can provide an open-air driving experience, they may not offer the same level of weather protection as a traditional hardtop roof.
- Maintenance: Convertible tops require regular cleaning and maintenance to ensure they remain in good condition, as they are exposed to the elements.
- Noise and insulation: Convertible tops may not provide the same level of insulation and noise reduction as a closed roof, which can lead to increased road noise and exposure to external sounds.
Overall, convertible tops are an essential component of a convertible car, offering the unique experience of open-air driving and adding a touch of style to the vehicle.
Why replace the convertible top?

- Noise reduction: A new convertible top can significantly reduce wind and road noise, making your driving experience more enjoyable and comfortable.
- Increase resale value: Replacing the convertible top can enhance the overall value of your BMW 325i, making it more appealing to potential buyers if you ever decide to sell.

After the front tension cables are attached, carefully adjust their tension to ensure proper fitting of the convertible top. The cables should provide enough tension to hold the top in place without causing any wrinkles or sagging.
Once you have adjusted the tension, double-check all the connections to make sure they are tight and secure. This will help prevent any issues or hazards during use.
Finally, test the convertible top by opening and closing it to ensure it operates smoothly. If you encounter any issues, go through the attachment process again and make any necessary adjustments.

Installing the rear window
Before installing the rear window on your 1987 BMW 325i convertible, make sure you have the necessary tools and materials, including a new rear window and a window adhesive kit. Follow these steps to properly install the rear window:
- Start by thoroughly cleaning the edges of the window opening to remove any dirt, debris, or old adhesive. Use a mild detergent and water solution, and make sure to dry the area completely.
- Apply a thin layer of the window adhesive to the edges of the window opening. Use the adhesive kit recommended by the manufacturer for best results.
- Carefully position the new rear window in the opening, making sure it is centered and aligned correctly. Gently press the window against the adhesive, allowing it to bond securely.
- Use masking tape to hold the window in place while the adhesive cures. Apply strips of tape across the top and sides of the window, making sure not to cover the surface of the window. This will help ensure a tight seal.
- Allow the adhesive to cure according to the manufacturer’s instructions. This may take several hours or even overnight. It is important to avoid moving or stressing the window during this time to ensure a proper bond.
- Once the adhesive has cured, carefully remove the masking tape. Inspect the window and its surrounding area for any signs of adhesive residue or excess. Use a clean cloth or a plastic scraper to gently remove any residue if necessary.
- Finally, give the newly installed rear window a thorough cleaning on both the inside and outside surfaces to remove any remaining dirt, fingerprints, or smudges. Use a high-quality glass cleaner and a lint-free cloth for best results.
