### **Pros and Cons of buying a Power K4746 Brake Hardware Kit for 2010-2011 Audi S4 / 2008-2011 Audi S5**
#### **Pros:** The Power K4746 brake hardware kit is a popular aftermarket upgrade for the 2008-2011 Audi S4/S5, offering several advantages:1. **Improved Braking Performance** The kit replaces the stock brake hardware with upgraded components, including larger calipers, high-performance rotors, and reinforced hardware. This results in better stopping power, especially under aggressive driving conditions.
2. **Enhanced Durability** The kit is designed to handle higher heat and stress compared to stock parts, reducing the risk of warping or failure over time. This is particularly beneficial for track use or heavy daily driving.
3. **Better Heat Dissipation** The larger rotors and upgraded calipers improve heat management, reducing brake fade during prolonged or intense braking sessions.
4. **Compatibility with Aftermarket Brake Pads** The kit allows for the use of high-performance brake pads, further improving braking efficiency and longevity.
5. **Aesthetic Appeal** The upgraded calipers and rotors provide a more aggressive and sporty look, which is appealing for enthusiasts who want to customize their vehicle.
6. **Widely Available and Trusted Brand** Power Stop is a well-known manufacturer in the aftermarket brake industry, with a reputation for quality and reliability. The K4746 kit is a proven upgrade for the S4/S5 platform.
7. **Easy Installation** While installation requires some mechanical skill, the kit is designed to fit standard S4/S5 brake systems with minimal modifications, making it accessible for DIY enthusiasts.

#### **Cons:** Despite its benefits, there are some drawbacks to consider before purchasing:1. **Cost** The kit is more expensive than stock brake hardware, with prices typically ranging from $800 to $1,200 depending on the retailer and additional components (e.g., pads, fluid). This is a significant investment for a non-essential upgrade.
2. **Potential for Overkill** For most street-driven S4/S5 owners, stock brakes are adequate. The K4746 kit is primarily beneficial for track use, aggressive daily driving, or those who frequently carry heavy loads. If your driving habits don t demand it, the upgrade may not be justified.
3. **Maintenance Requirements** Upgraded brakes require more frequent inspections and maintenance, such as rotor resurfacing or replacement at shorter intervals than stock parts. This adds to long-term costs.
4. **Potential for Brake Dust Issues** Larger rotors and high-performance pads can produce more brake dust, which may require more frequent cleaning of wheels and tires.
5. **Compatibility with Stock Suspension** While the kit is designed to fit, some users report that the upgraded calipers may rub against the wheel wells or require minor adjustments to the suspension or brake lines for proper clearance.
6. **Learning Curve for Installation** If you re not experienced with brake work, the installation process can be complex, especially if you re also upgrading pads, rotors, or fluid. Professional installation may be necessary, adding to the cost.
7. **Potential for Overheating Without Proper Use** If the brakes are not used appropriately (e.g., excessive track use without adequate cooling), the upgraded hardware may overheat, reducing lifespan and performance.

### **Conclusion:**The Power K4746 brake hardware kit is a solid upgrade for Audi S4/S5 owners who prioritize performance, durability, and track-ready braking. It is particularly valuable for those who push their vehicles hard, carry heavy loads, or plan to engage in track days. However, for casual street drivers, the cost and maintenance requirements may not be justified by the benefits.
If you frequently drive aggressively, participate in track events, or want a noticeable performance and aesthetic upgrade, the K4746 kit is a worthwhile investment. For those who primarily use their S4/S5 for daily commuting or light driving, stock brakes or a more modest upgrade (such as aftermarket pads and rotors without caliper upgrades) may be sufficient.
### **Recommendation:**- **Buy the K4746 kit if:** You drive aggressively, plan to use your S4/S5 on the track, or want a significant performance and visual upgrade. Ensure you pair it with high-quality brake pads (e.g., EBC RedStuff or Hawk HPS) and fresh brake fluid for optimal results.
- **Avoid the K4746 kit if:** You primarily drive on the street without aggressive braking demands, as the cost and maintenance may not be worth it. Consider a more budget-friendly brake upgrade (e.g., EBC or Hawk rotors with stock calipers) instead.
- **Additional Tips:** If you proceed with the upgrade, research installation guides thoroughly or consult a professional mechanic to ensure proper fitment and avoid common pitfalls. Monitor brake performance and maintenance needs closely to maximize the kit s lifespan.
