### **Pros and Cons of buying a WhisperBar 51930 S37W Roof Rack Bars with K930W SmartFoot Kit and Yakima Mounting System**

1. **Durability and Strength** The WhisperBar 51930 S37W is designed with a **7075-T6 aluminum alloy**, which is highly resistant to corrosion and provides excellent structural integrity. This ensures the bars can handle heavy loads without bending or breaking.

2. **Lightweight Construction** Despite its strength, the bars are relatively lightweight compared to steel alternatives, reducing overall vehicle weight and improving fuel efficiency.

3. **Versatile Mounting Options** The **K930W SmartFoot Kit** allows for flexible installation angles, making it easier to fit the bars on vehicles with unique roof contours or limited clearance. This adaptability is particularly useful for SUVs, trucks, and crossovers.

4. **Compatibility with Yakima Mounting System** The inclusion of a **Yakima-compatible mounting system** means you can easily attach various roof accessories (cargo boxes, bike racks, kayak mounts, etc.) without needing additional hardware. Yakima is a well-known brand for roof gear, ensuring a secure and reliable fit.

5. **Aesthetic Appeal** The **S37W model** features a sleek, low-profile design that blends well with modern vehicles, reducing wind noise and drag compared to bulkier roof racks.

6. **Easy Installation** The SmartFoot system simplifies the mounting process, as it allows for adjustments without removing the bars entirely. This can save time and effort during installation or modifications.

7. **Corrosion Resistance** The anodized finish on the WhisperBar ensures long-term resistance to rust and weathering, making it suitable for frequent outdoor use.

8. **Load Capacity** The bars are rated for **heavy-duty use**, typically supporting loads of **100 150 lbs per bar** (depending on the specific model and mounting configuration), which is sufficient for most roof-mounted gear.

9. **Minimal Wind Noise** The low-profile design helps reduce aerodynamic drag and wind noise, making for a quieter ride compared to taller roof racks.

10. **Warranty and Support** WhisperBar offers a **limited lifetime warranty** on their products, providing peace of mind against manufacturing defects. Additionally, their customer support is often praised for responsiveness.

1. **Higher Upfront Cost** Compared to basic roof rack systems, the WhisperBar 51930 S37W with the SmartFoot Kit and Yakima mounts is **more expensive**. The premium price reflects the materials and features, but it may not be justified for casual users who don t need heavy-duty capacity.

2. **Complex Installation for Some Users** While the SmartFoot system simplifies adjustments, the initial installation can still be **time-consuming and technically challenging**, especially for those without prior experience with roof racks. Proper alignment is critical to avoid stress on the vehicle s roof rails.

3. **Limited Color Options** WhisperBar s products are primarily available in **natural aluminum or matte black**, which may not appeal to those seeking custom colors or finishes.

4. **Potential for Misalignment Over Time** If not installed correctly or if the vehicle s roof rails shift (due to age or wear), the bars may become misaligned, leading to uneven load distribution or reduced stability.

5. **Not Universal Fit** While the SmartFoot Kit improves compatibility, some vehicles particularly those with **non-standard roof contours or aftermarket modifications** may still require custom solutions or additional adapters.

6. **Maintenance Requirements** Although the anodized finish is durable, it can **scratch or chip** over time, especially if the bars are exposed to sharp objects (e.g., branches, debris). Regular cleaning with mild soap and water is recommended to prevent corrosion.

7. **Weight Distribution Considerations** While the bars are lightweight, improperly loaded gear (e.g., placing heavy items too far forward or backward) can still affect handling and stability. Users must ensure even weight distribution.

8. **Potential for Roof Rail Damage** If the installation is not done carefully, there s a risk of **scratching or damaging the vehicle s roof rails**, especially on painted or clear-coated surfaces. Proper protective measures (e.g., tape, padding) are necessary.

9. **Limited Aftermarket Support** While Yakima is a reputable brand, some users may find that **third-party accessories** (e.g., bike racks, cargo boxes) are not always optimized for WhisperBar s specific mounting points, requiring additional adapters.

10. **Resale Value Impact** While high-quality, roof racks are not typically considered high-value accessories. If you plan to sell the vehicle later, the rack may not add significant resale appeal unless it s a standard feature.

The **WhisperBar 51930 S37W with K930W SmartFoot Kit and Yakima mounting system** is an **excellent choice for serious outdoor enthusiasts, frequent travelers, or anyone who needs a **durable, lightweight, and versatile roof rack system**. Its **superior materials, adaptability, and compatibility with high-quality accessories** make it a top-tier option for those who prioritize **performance, longevity, and ease of use**.

However, the **higher cost, complexity of installation, and potential maintenance needs** may not be worth it for **casual users or those on a tight budget**.

For **heavy-duty use (e.g., hauling kayaks, ATVs, or large cargo boxes), the WhisperBar s strength and adjustability justify the investment**. The **SmartFoot Kit** is particularly valuable for vehicles with **unique roof shapes**, while the **Yakima compatibility** ensures seamless integration with a wide range of accessories.
