Review PORSCHE Front Sway Bar 20mm Stabilizer Factory Orignal 911s fits CARRERA 911

The **Porsche 911 (930/934) Front Sway Bar 20mm Stabilizer (Original Part #34370310)** is a meticulously crafted, high-performance suspension component designed exclusively for the iconic **911 (911S, 911SC, Carrera 2.7L, Carrera 3.2L, and Carrera RS)** models from the late 1970s and early 1980s. This genuine Porsche front stabilizer bar is a direct replacement for the factory-equipped part, ensuring perfect fitment, alignment, and handling characteristics that Porsche engineers originally intended. Crafted from high-grade, heat-treated steel, this stabilizer bar is built to withstand the demands of spirited driving, aggressive cornering, and long-term durability, maintaining its structural integrity even under extreme loads. The **20mm diameter** design strikes an optimal balance between stiffness and compliance, enhancing lateral rigidity while allowing subtle body roll to improve traction and stability at high speeds. Unlike aftermarket alternatives that may compromise fitment or material quality, this original part preserves the classic **911 s** legendary road-hugging precision, delivering a sharper, more responsive steering feel and reducing body lean during aggressive maneuvers. Whether restoring a vintage Porsche to its original specification or upgrading a modernized suspension setup, this stabilizer bar ensures a seamless integration with the **911 s** front anti-roll bar mounts, bushings, and control arms, guaranteeing a factory-like performance that enthusiasts and purists demand. Its robust construction and precise engineering make it an essential component for those seeking to maintain or restore the unmistakable **911 s** dynamic handling where raw power meets razor-sharp cornering ability.

### **Pros and Cons of Buying an Original Porsche 911 (930/934) Front Sway Bar (20mm Stabilizer) for a 911S/911SC/Carrera**

1. **Authentic Fitment** The original sway bar is designed specifically for the 911 s front suspension, ensuring proper alignment and handling characteristics that match the car s intended performance.

2. **Durability** Porsche s original components are built to last, often outlasting aftermarket alternatives, especially if properly maintained.

3. **Reliability** Since it s a genuine part, it won t fail unexpectedly due to material or design flaws common in cheaper knockoffs.

4. **Resale Value** Keeping original parts helps maintain the car s value, especially for collectors or enthusiasts who prioritize authenticity.

5. **Handling Precision** The original sway bar contributes to the 911 s classic understeer bias and balanced cornering, which aftermarket bars may not replicate perfectly.

6. **Compatibility with Stock Suspension** Unlike stiffer aftermarket bars, the original part works seamlessly with stock springs, shocks, and bushings, avoiding potential binding or uneven wear.

7. **Aesthetic Consistency** The original bar matches the car s factory appearance, which is important for show cars or those aiming for a stock look.

1. **Cost** Original Porsche parts are significantly more expensive than aftermarket alternatives, often costing **$200 $400 ** depending on condition and source.

2. **Limited Availability** Finding a genuine original part in good condition can be difficult, especially for older models like the 911S/SC/Carrera. Some may require sourcing from salvage yards or international suppliers.

3. **Potential for Wear** If the car has high mileage or a history of rough handling, the original bar may already be worn or damaged, requiring replacement anyway.

4. **No Performance Gain Over Stock** Unlike aftermarket bars designed for track use, the original 20mm bar is not stiffer than stock it simply restores the car to its intended specification.

5. **Installation Complexity** Replacing a sway bar requires removing the wheel, adjusting the steering rack, and ensuring proper torque settings, which may not be a simple DIY job for beginners.

6. **No Upgrade Benefits** If the goal is improved cornering or reduced body roll, aftermarket bars (e.g., 18mm or 16mm) or coilovers may offer better results at a lower cost.

### **Conclusion & Recommendation**

- You are restoring a classic 911 to **stock specification** for show, concours, or historical accuracy.

- You want **long-term reliability** and don t mind the higher cost.

- The car s current bar is **damaged or missing**, and you prefer a genuine replacement over an aftermarket part.

- You are **modifying the car for better handling** (e.g., track use, aggressive driving), an **aftermarket bar (16mm 18mm) or coilover setup** may be more cost-effective and beneficial.

- You are on a **tight budget**, aftermarket alternatives (e.g., **Eibach, Bilstein, or OEM-equivalent bars**) offer similar stiffness at a fraction of the cost.

- The car already has **stock suspension components** and the sway bar is in decent condition, replacement may not be necessary.

- **For a stock-restoration project or concours car:** **Buy the original 20mm sway bar** if available and within budget.

- **For performance or cost savings:** Consider an **aftermarket 16mm 18mm bar** (e.g., **Porsche 911-specific aftermarket bars from brands like Eibach or Bilstein**) or a **full suspension upgrade** (e.g., **coilovers with adjustable bars**).

- **If unsure:** Consult a **Porsche specialist** or **suspension expert** to assess whether the original bar is truly needed or if an aftermarket solution would suffice.

The original part is the **purest choice** for authenticity, but practicality and performance goals should also guide the decision.
