Review PORSCHE 986/987 Front Suspension Crossmember Bars Oem fits BOXSTER 911 1999–2008

The **Porsche 996 50443300 (986/987) Boxster Front Suspension Crossmember Bars** are a precision-engineered aftermarket upgrade designed to enhance the handling, stability, and overall driving dynamics of the iconic 1999 2008 911 996 Boxster (986/987) chassis. These high-quality suspension components replace the stock front crossmember, which is often criticized for its softness, lack of rigidity, and tendency to flex under aggressive cornering or high-speed maneuvers, leading to a less responsive and slightly vague steering feel. Crafted from durable, lightweight materials typically high-grade aluminum or reinforced steel these aftermarket bars are engineered to provide superior torsional stiffness, effectively reducing body roll and improving weight distribution across the front axle. This results in tighter, more predictable handling, particularly in spirited driving scenarios where the 996 s naturally understeer-prone nature might otherwise dominate. Beyond their performance benefits, these crossmember bars also offer a subtle aesthetic upgrade, as they often feature sleek, contoured designs that complement the Boxster s sporty silhouette while maintaining full compatibility with the factory suspension geometry. Whether paired with stiffer springs, upgraded bushings, or a full suspension kit, these bars serve as a foundational component for those seeking to transform their 996 Boxster into a more agile, composed, and driver-focused machine. Ideal for both track-focused enthusiasts and daily drivers looking to refine their car s cornering capabilities, these suspension bars are a straightforward yet impactful modification that bridges the gap between stock comfort and high-performance precision.

### **Pros and Cons of Buying a 1999 2008 Porsche 996/986/987 Boxster (911 996 50443300 Front Suspension Crossmember Bars)**

#### **Pros**

1. **Iconic Design and Legacy**

The 996 Boxster (and its 911 counterpart) is a cult classic, representing a transitional era in Porsche s history. Its aggressive, angular styling and rear-engine layout remain desirable among enthusiasts. The 986 (1997 2000) and 987 (2005 2008) iterations refined this design with improved aerodynamics, better handling, and more modern engineering.

2. **Performance and Driving Dynamics**

- **Engine Options:** The 996 Boxster came with either a 3.4L (204 hp) or 3.6L (245 hp) M96 engine, while the 987 introduced a turbocharged 3.4L (320 hp) and later a naturally aspirated 3.8L (350 hp). These engines deliver strong power-to-weight ratios, especially in the lighter Boxster models.

- **Handling:** The 996/987 chassis is praised for its precise steering, balanced weight distribution, and engaging rear-wheel-drive dynamics. The 987, in particular, benefited from updated suspension tuning and a lower center of gravity.

- **Turbo Models (987):** The 987 Turbo (997 s predecessor in Boxster form) offers near-luxury sports car performance with a 320 hp turbocharged engine, making it a standout in its class.

3. **Reliability and Durability**

- The 996 and 987 are generally robust, especially if maintained properly. The M96 engine (3.4L/3.6L) is known for longevity with regular oil changes and valve adjustments (every 60,000 90,000 miles).

- The 987 s turbo engine is more complex but has proven reliable with proper care, particularly if the turbo and intercooler have been serviced.

- Porsche s reputation for build quality means many of these cars still hold up well after 20 years, especially if they ve been well-kept.

4. **Aftermarket Support and Modifications**

- The 996/987 has a vast aftermarket, with parts ranging from suspension upgrades (e.g., coilovers, sway bars) to engine tuning (e.g., cold air intakes, exhaust systems).

- Tuning options like **Porsche Performance Parts (PPP), Borla, or Akrapovic exhausts** can enhance performance and sound.

- The open-top nature of the Boxster makes it a popular choice for conversions (e.g., soft tops, hardtops, or even full conversions to a roadster).

5. **Affordability Compared to Modern Porsche Models**

- A well-maintained 996 or 987 Boxster is significantly cheaper than a new or even lightly used modern Porsche (e.g., 718 Cayman or 911 GT3). This makes it an attractive entry point into Porsche ownership.

- Parts and labor costs are also lower than for newer models, though some rare or high-end components (e.g., original soft top, leather interior) can be pricey.

6. **Collectibility and Investment Potential**

- Lower-mileage, well-documented examples especially **987 Turbos, 987 3.8L models, or 996 3.6L cars** can appreciate in value over time, particularly if they retain originality or have desirable options (e.g., PDK transmission in the 987).

- The 996 s "ugly duckling" status has shifted; many now consider it a desirable era, increasing demand for restored examples.

7. **Convertible Practicality**

- Unlike a hardtop 911, the Boxster s soft top is convenient for daily use, offering easy access to the interior and a more casual driving experience. Many owners appreciate the ability to roll down the top on warm days.

#### **Cons**

1. **Aging Design and Practicality Issues**

- **996 (1999 2004):** The 996 s styling is divisive many find it "ugly" compared to the 986 s more refined look. The rear end s aggressive shape and lack of a proper rear spoiler (until the 997) make it less aerodynamic than later models.

- **Interior Quality:** The 996 s interior is functional but dated by modern standards, with hard plastics, less refined materials, and a less premium feel than the 987 or later models.

- **Rear Visibility:** The Boxster s rear window is small, and blind spots are larger than in a coupe or modern Porsche.

2. **Common Reliability Concerns**

- **Valve Adjustment:** The hydraulic lifters require adjustment every 60,000 90,000 miles; neglecting this can lead to knocking and engine damage.

- **Oil Consumption:** Some 3.6L models (especially pre-2002) can burn oil; checking levels regularly is crucial.

- **Water Pump and Thermostat Issues:** The 996 s cooling system has had reliability issues, particularly with the water pump and thermostat housing (a known failure point).

- **Turbocharger Reliability:** Early 987 Turbos (pre-2006) had issues with turbo failure due to oil starvation or wastegate problems. Later models improved but still require vigilant maintenance.

- **Intercooler and Charge Pipe:** The intercooler and charge pipes are prone to cracking or leaking, especially in hot climates.

- **Exhaust Manifold:** Some models developed cracks in the exhaust manifolds, leading to coolant leaks.

- The 996 s **5-speed manual** is smooth but lacks the precision of later PDK or 7-speed dual-clutch transmissions.

- The **987 s PDK (2005 2008)** is a game-changer, offering near-instant shifts, but it requires proper servicing (fluid changes every 30,000 60,000 miles).

3. **Maintenance and Repair Costs**

- While cheaper than modern Porsches, repairs can still add up, especially for rare or high-mileage parts. The 996/987 is not as common as a 911, so finding a specialist can be harder.

- **Soft Top Wear:** The original soft top is expensive to replace ( $5,000 $8,000), and aftermarket tops may not fit as well.

- **Suspension and Steering:** The 996 s front suspension (especially the crossmember bars you mentioned) can wear out over time, requiring bushings or even a full rebuild.

4. **Fuel Economy and Running Costs**

- The 996/987 is not fuel-efficient by modern standards. The 3.4L/3.6L models average **18 22 MPG (city/highway)**, while the turbo models sip **16 20 MPG**. Gasoline prices can significantly impact ownership costs.

- **Insurance:** While cheaper than a 911, a Boxster can still be expensive to insure, especially for high-performance or turbo models.

5. **Resale Value and Depreciation**

- The 996 has historically depreciated faster than the 987, though appreciation has picked up in recent years for well-maintained examples.

- The 987 holds value better, particularly the **Turbo and 3.8L models**, but even these will never match the resale of a modern Porsche.

6. **Noise and Comfort**

- The 996/987 is louder than later Porsches, with noticeable wind noise at highway speeds (especially the 996) and a less insulated cabin.

- The seats are supportive but not as plush as modern Porsche models, and the ride can be firm, making long drives less comfortable.

7. **Legal and Practical Limitations**

- **Soft Top Restrictions:** Some regions have laws restricting convertible driving in certain weather conditions (e.g., rain, high winds).

- **Weight Limitations:** The Boxster s lighter weight is an advantage for handling but can make it feel less stable at high speeds compared to a heavier 911.

---

### **Conclusion**

The **1999 2008 Porsche 996/986/987 Boxster** is a fantastic choice for enthusiasts who prioritize **driving enjoyment, classic Porsche heritage, and affordability** over modern luxury and efficiency. It offers **strong performance, engaging handling, and a cult following**, making it a rewarding car to own. However, it requires **diligent maintenance**, especially for the **M9
