Rolling Arches: Modifying Your Mk2 Golf

how to roll arches mk2 golf

Volkswagen Golf Mk2 owners often modify their vehicles by fitting custom wheels and tyres. This requires rolling the arches, which involves drilling out the rivets, grinding the top one, and then re-riveting. Some owners opt to use double-sided tape for the rivets that were ground out. This process creates more space in the wheel arches, allowing for larger wheels and tyres to be installed. It is a popular modification, as evidenced by its discussion on forums dedicated to Volkswagen enthusiasts.

Drilling out rivets

When drilling out rivets, there are several methods that can be employed:

  • Using a Rivet Removal Tool: This tool is designed to centre the drill bit on the head of the rivet, making it easy to drill out.
  • Centering with the Dimple: The dimple in the head of the rivet can be used to centre a drill bit manually. The bit is slowly worked into the head until it no longer slides off, and then drilling can begin.
  • Drilling from the Inside: This method involves drilling through the rivet from the back end and then drilling out the head. This approach can require less force as it weakens the rivet from the inside.

It is important to note that the drill bit size should match the size of the rivet. Additionally, creating a small dimple in the factory head of the rivet can help with centering the drill bit. Once the drill bit is centred, it should be tilted to ensure the hole is drilled straight through the centre of the rivet.

After drilling out the rivets, there are various options for replacement. Some people choose to use machine screws, while others opt for industrial velcro or double-sided tape. It is important to consider the advantages and disadvantages of each method, such as the potential for screws to promote rust or the ease of removal with velcro. Ultimately, the chosen method will depend on the specific requirements and preferences of the individual.

Grinding the top rivet

When it comes to grinding the top rivet on your MK2 Golf, there are several important steps to follow. Firstly, it's essential to have the right tools and safety gear. Ensure you have eye protection and gloves to prevent any injuries from grinding debris. Next, you'll need a suitable grinder, preferably one with a thin grinding disc that can reach the rivet without damaging the surrounding area. Before you begin grinding, it's crucial to understand the process and proceed with caution. Here are the steps to follow:

Drill Out the Rivets: Before grinding, you'll need to remove the rivets. Using a drill, carefully drill out the rivets holding the arch in place. Make sure to drill out all the rivets except the top one, which you will grind.

Secure the Workpiece: Clamp or secure the arch firmly in place to ensure it doesn't move during the grinding process. This step is crucial for your safety and achieving a precise grind.

Grind the Top Rivet: With the arch secured, carefully position the grinder so that the grinding disc makes contact with the top rivet. Apply gentle pressure and grind the rivet down until it's flush with the arch. Take your time and work methodically to avoid damaging the arch or creating an uneven surface.

Clean the Area: Once you've finished grinding, use a brush or compressed air to remove any metal shavings or debris from the area. It's important to ensure the area is clean before proceeding to the next step.

Replace the Rivets: After grinding the top rivet, you can replace the rivets you drilled out. Consider using double-sided tape to secure the arch, and then re-rivet the holes you created. This will help ensure a secure and sturdy fit for the arch.

By following these steps and paying attention to safety, you can successfully grind the top rivet when rolling arches on your MK2 Golf. Remember to work carefully and methodically, and always wear the appropriate protective gear.

Replacing rivets with double-sided tape

When it comes to rolling arches on a Mk2 Golf, one of the key considerations is how to manage the rivets. While some people choose to grind the arches, this can weaken them. An alternative approach is to drill out the rivets, grind the top one, and then replace the rivets with double-sided tape.

This method allows you to retain the strength of the arch while still achieving the desired clearance for your wheels. By using double-sided tape, you can securely attach the plastic arches back in place after rolling them. This tape method is also mentioned by a user on a forum who says they will "finish the other arch and post some pics and maybe a how-to".

It is important to note that the process of rolling arches on a Mk2 Golf may vary depending on the specific model and modifications made to the vehicle. Some Mk2 Golf models have plastic arch covers, while others do not, which can impact the rolling process. Additionally, the amount of rolling required may differ based on the size and offset of the wheels being installed.

When replacing rivets with double-sided tape, it is crucial to use a strong and durable tape that can withstand the stresses of the road. It is also important to ensure that the surface is clean and free of debris before applying the tape to ensure a secure bond.

Overall, replacing rivets with double-sided tape when rolling arches on a Mk2 Golf can be a viable option to consider. It allows for the necessary adjustments to be made while maintaining the integrity of the arches and providing a smooth finish.

ET and tyre sizes

When modifying a car, such as a Mk2 Golf, it is important to understand the relationship between wheel and tyre sizes. The ET value, or "Einpresstiefe" in German, represents the depth of imprint and is a key definition of any vehicle wheel rim. It is the distance between the hub mounting face and the centre line of the wheel.

The ET value is critical when choosing wheel sizes. The width of the tyre is dictated by the width of the wheel. An incorrect tyre width can cause severe damage to the wheels and the car, and even lead to tyre explosions and accidents. Therefore, it is crucial to select the appropriate tyre size and width for the specific wheel.

In the context of the Mk2 Golf, one owner shared their experience with wheel and tyre sizes. They mentioned having 7.5x16 ET 35 wheels with 195/40/16 tyres and 7.5x17 ET25 wheels with 195/40/17 tyres on their 20v Mk2 Golf. These values provide a reference for others considering similar modifications.

It is worth noting that changing tyre sizes can affect the handling of the car, and changing the wheel ET can have even more significant impacts. A positive offset pushes the wheel deeper into the arch, while a negative offset substantially changes the car's appearance. If the offset is incorrect, the wheel may sit too deep inside the wheel arch, leading to rubbing issues with the suspension and potential damage. Therefore, it is recommended to always double-check the wheel ET and perform a test fit to ensure a safe and proper installation.

Arch trims

When it comes to arch trims for a Mk2 Golf, there are a variety of options and methods available. One popular method for achieving the desired arch is to roll the arches. This process involves physically manipulating the metal of the arches to create a smooth, curved appearance. It is a common practice for Mk2 Golf owners who want to fit larger wheels and tyres.

There are a number of ways to roll arches, and one method suggests drilling out the rivets, grinding the top one, and then replacing the rivets with double-sided tape before re-riveting. This process allows for a more precise adjustment of the arch, ensuring a perfect fit for the desired wheel and tyre setup.

Another important consideration when rolling arches is the use of arch trims. Arch trims are available for both the front and rear arches of the Mk2 Golf, and they play a crucial role in enhancing the overall appearance of the car. They help to cover any gaps or imperfections that may be present after rolling the arches, creating a seamless and sleek look.

When choosing arch trims, it is important to select the correct size and style that complement the wheels and tyres. The arch trims should follow the contour of the arches, providing a smooth transition from the wheel well to the body of the vehicle. It is worth noting that arch trims are available in various materials, finishes, and colours, allowing owners to customise their Mk2 Golf to their desired style.

In addition to arch trims, there are other trim components available for the Mk2 Golf that can further enhance its aesthetic appeal. These include front grille trim clips, exterior trim clips, rear stone guard trim, and sill trim strips. By combining these trim elements with the arch trims, Mk2 Golf owners can achieve a cohesive and customised look for their vehicle.
