### **Pros and Cons of buying a BMW E90 328i/335i Left Rocker Moulding Skirt (P/N 51777202651, 2009 2011 Models)**

1. **Improved Aerodynamics** The rocker moulding skirt reduces airflow turbulence under the car, slightly improving stability at high speeds and reducing drag, which can enhance fuel efficiency and handling.

2. **Enhanced Aesthetics** The skirt adds a sportier, more aggressive look to the car, particularly noticeable on the lower body panels. This can be appealing if you prefer a more aggressive or race-inspired appearance.

3. **Potential Performance Benefits** While the impact on performance is minor, some drivers report slight improvements in downforce and cornering grip, especially at higher speeds, due to the reduced underbody airflow.

4. **Compatibility with Aftermarket Mods** If you plan to add other performance or cosmetic upgrades (e.g., lower suspension, wider wheels, or a rear diffuser), the skirt can complement those modifications by maintaining a clean, aerodynamic profile.

5. **Easy Installation** The part is designed for straightforward installation, typically requiring only basic tools (no welding or extensive bodywork). Most mechanics or DIY enthusiasts can fit it in a few hours.

6. **Durability** Made from high-quality plastic, the skirt is resistant to UV damage and minor impacts, though it may require occasional cleaning to prevent dirt buildup.

7. **OEM Quality** As an original BMW part, it meets the manufacturer s standards for fitment and materials, ensuring a professional finish.

1. **Minimal Performance Gain** The aerodynamic benefits are subtle. For most drivers, the difference in handling or fuel economy will be negligible unless the car is heavily modified or driven at high speeds regularly.

2. **Cost vs. Benefit** The part is not cheap (typically $100 $200 depending on source), and the aesthetic improvement may not justify the expense for every owner. If you re not particularly concerned about the look or minor aerodynamics, the cost may not be worth it.

3. **Installation Challenges** While generally easy, fitting the skirt may require careful alignment to avoid gaps or misalignment, especially if the car has been previously modified or has bodywork imperfections.

4. **Potential for Damage** The skirt is vulnerable to chips or cracks from road debris, especially if you drive on rough roads or park in areas with sharp objects. It may also scratch if not cleaned regularly.

5. **Limited Practical Use** Unlike more functional mods (e.g., exhaust upgrades or suspension tuning), the skirt s primary purpose is cosmetic. If you prioritize performance over appearance, the investment may feel unnecessary.

6. **Compatibility Issues** Ensure the part fits your exact model year and variant (328i vs. 335i). Some aftermarket skirts may not align perfectly with OEM bodywork, leading to gaps or a poor finish.

7. **Maintenance Overhead** Unlike underbody armor or protective panels, the skirt doesn t offer any practical protection. It s purely decorative, so the effort to keep it clean and intact is mostly for aesthetic reasons.

### **Conclusion**

The **BMW E90 328i/335i left rocker moulding skirt (P/N 51777202651)** is a modest but worthwhile upgrade for owners who prioritize aesthetics and minor aerodynamic refinements. The installation is straightforward, and the part enhances the car s sporty appearance without requiring significant modifications. However, the performance benefits are minimal, and the cost may not be justified for those who aren t concerned with the look or high-speed handling.

If you already have or plan other performance or cosmetic upgrades (e.g., a rear diffuser, lower suspension, or wider wheels), the skirt can serve as a cohesive finishing touch. For drivers who simply want a cleaner underbody or a more aggressive stance, it s a reasonable investment. Conversely, if your priorities lie elsewhere (e.g., engine upgrades, interior comfort, or reliability), the money could be better spent elsewhere.

---

### **Recommendation**

- You want a subtle but noticeable aesthetic improvement to the car s lower body.

- You re adding other performance mods (e.g., rear diffuser, lower springs) and want the skirt to complement them.

- You drive at high speeds frequently and appreciate minor aerodynamic refinements.

- You re comfortable with a modest investment for cosmetic value.

- You re not concerned about the car s appearance and prefer to allocate funds toward more impactful upgrades (e.g., exhaust, suspension, or engine tuning).

- You drive in areas with rough roads or heavy debris, as the skirt may chip or scratch easily.

- You prioritize practicality over aesthetics and see the cost as unnecessary for the minimal benefits.

- If you like the look but want a more durable option, consider aftermarket skirts with reinforced materials or protective coatings.

- If you re unsure, test-fit the part before purchasing to ensure it aligns perfectly with your car s bodywork.

- If you re modifying the car extensively, group the purchase with other related parts (e.g., a rear diffuser or front splitter) to maximize the aerodynamic effect.
