If you own an Audi B7 S4, you know that it's a high-performance machine that demands top-notch parts and maintenance. One area where many Audi owners choose to upgrade is the suspension system. Upgrading your bushings can improve handling, reduce noise and vibration, and provide a more comfortable ride. In this article, we'll take a closer look at Audi B7 S4 bushings and provide some tips and tricks for upgrading your suspension.
What Are Bushings and Why Do They Matter?
Bushings are small rubber or polyurethane components that are used to connect various parts of the suspension system. They act as a buffer between metal components, reducing noise and vibration while also providing a degree of flexibility that allows the suspension to move smoothly. Over time, bushings can wear out, crack, or become damaged, leading to increased noise and vibration, reduced handling, and a less comfortable ride.
Upgrading your bushings can provide a number of benefits. Polyurethane bushings are stiffer than rubber, providing better handling and reduced body roll. They also have a longer lifespan than rubber bushings, making them a popular choice for enthusiasts. However, polyurethane bushings can be more expensive and may produce more noise and vibration than rubber.
Types of Bushings
Rubber Bushings
Rubber bushings are the most common type of bushing used in the suspension system. They are affordable, durable, and provide a comfortable ride. However, rubber bushings can wear out more quickly than polyurethane bushings and may not provide the same level of performance.
Polyurethane Bushings
Polyurethane bushings are stiffer than rubber and provide better handling and reduced body roll. They also have a longer lifespan than rubber bushings, making them a popular choice for enthusiasts. However, polyurethane bushings can produce more noise and vibration than rubber and may be more expensive.
When to Replace Your Bushings
There are a few signs that your bushings may need to be replaced. If you notice increased noise or vibration while driving, particularly when going over bumps or rough roads, it may be time to replace your bushings. You may also notice a clunking or knocking sound when turning or going over bumps. Poor handling, increased body roll, and uneven tire wear can also be signs that your bushings are worn out.
If you're unsure whether your bushings need to be replaced, it's always a good idea to have your vehicle inspected by a professional mechanic. They can identify any issues and recommend the best course of action.
Tips for Upgrading Your Bushings
Choose the Right Type of Bushing
When upgrading your bushings, it's important to choose the right type for your needs. Rubber bushings provide a comfortable ride and are more affordable, but may not provide the same level of performance as polyurethane. Polyurethane bushings are stiffer and provide better handling, but may produce more noise and vibration and be more expensive.
Replace All Bushings at Once
If you're upgrading your bushings, it's a good idea to replace all of them at once. This will ensure that your suspension system is balanced and that all components are working together properly. Replacing just one or two bushings can lead to uneven wear and handling issues.
Have Your Vehicle Aligned
After upgrading your bushings, it's important to have your vehicle aligned. This will ensure that your suspension system is properly adjusted and that your tires are wearing evenly. A professional alignment can also improve handling and reduce wear on your tires.
Conclusion
Upgrading your bushings can provide a number of benefits, including improved handling, reduced noise and vibration, and a more comfortable ride. Whether you choose rubber or polyurethane bushings, it's important to choose the right type for your needs and replace all of your bushings at once. With these tips and tricks, you can upgrade your suspension system and get the most out of your Audi B7 S4.
