Review BFO 4x Engine Transmission Pitch Mount Subaru 1993 fits IMPREZA WRX 2014–2017

The **BF0 A5MLB3 4x Engine Transmission Pitch Mount** is a high-performance, precision-engineered suspension component meticulously designed to enhance the handling, durability, and drivability of Subaru Impreza WRX models spanning from the classic 1993 through 2014 (including the FC and FD generations) as well as the more modern 2014 2017 GC models. Crafted from high-grade, heat-treated steel, this mount is built to withstand the rigorous demands of aggressive driving, heavy loads, and prolonged use under demanding conditions, ensuring long-term reliability without compromising performance. The A5MLB3 mount replaces the stock pitch mount, which is often a common failure point in Subaru vehicles prone to excessive wear from torque loads, especially in high-performance or overloaded setups. By reinforcing the connection between the engine/transmission assembly and the subframe, this mount significantly reduces unwanted movement, torsional flex, and drivetrain vibration, resulting in a more composed, responsive, and engaging driving experience. Whether you're tackling twisty roads, pushing the limits on the track, or simply seeking a more refined ride, this mount delivers a noticeable improvement in steering precision, throttle response, and overall vehicle stability. Its robust construction also helps mitigate the risk of costly drivetrain damage by maintaining proper alignment and reducing stress on critical components like the driveshaft, transmission, and engine mounts. Installation is straightforward, requiring only basic tools, and the mount is fully compatible with a wide range of aftermarket suspension upgrades, including coilovers, sway bars, and lift kits, making it an essential component for any serious Subaru enthusiast looking to optimize their vehicle s performance and longevity. With its blend of durability, precision engineering, and adaptability, the BF0 A5MLB3 is a must-have upgrade for those who demand the best from their WRX.

### **Pros and Cons of buying a BFO A5MLB3 4x Engine Transmission Pitch Mount for Subaru Impreza (1993-2014 WRX) & STI (2014-2017)**

1. **Improved Engine Mounting Stability** The A5MLB3 is designed to reduce engine movement, especially under heavy acceleration, braking, or aggressive driving. This can help prevent excessive flex in the engine bay, which may lead to premature wear on mounts, hoses, and wiring.

2. **Enhanced Durability** BFO (Billet Fabrication Outlet) is known for producing high-quality, billet aluminum mounts that are stronger and more resistant to fatigue compared to stock rubber mounts. This can extend the lifespan of your engine mounts, reducing the risk of failure over time.

3. **Better Vibration Dampening** While not as effective as rubber mounts, the A5MLB3 provides a firmer, more structured mount that can help isolate some engine vibrations, potentially improving cabin comfort and reducing strain on other components.

4. **Compatibility with Performance Mods** If you ve added power (turbocharging, forced induction, or engine swaps), a stiffer mount like this can help prevent excessive movement that could damage other systems.

5. **Easy Installation** The mount is designed to replace the stock rubber mount with minimal modifications, making it a straightforward upgrade for DIYers.

6. **Corrosion Resistance** Billet aluminum is less prone to rust and degradation compared to some aftermarket rubber mounts, which can be an issue in harsh environments.

---

1. **Less Vibration Isolation** Unlike stock rubber mounts, the A5MLB3 is a solid (or nearly solid) mount, meaning it will transmit more engine vibrations into the chassis. This could lead to a harsher ride and increased stress on the firewall, suspension, and drivetrain over time.

2. **Potential for Increased Strain on Other Components** A stiffer mount system can put more load on the firewall, transmission mounts, and subframe, which may accelerate wear in those areas if they re already worn or weak.

3. **Not Ideal for Stock or Mild Builds** If your vehicle is stock or lightly modified, the benefits of this mount may not be noticeable, and the trade-off in vibration transfer could be more of a drawback than an advantage.

4. **Cost** While not extremely expensive, billet mounts are more costly than basic rubber replacements. If you re on a tight budget, this may not be the best immediate upgrade.

5. **Potential for Over-Tightening Risks** Since the mount is stiffer, improper installation (e.g., overtightening) could cause stress cracks in the firewall or transmission housing.

6. **Limited Aftermarket Support** If issues arise, finding specialized repair help for billet mounts may be harder than for standard rubber mounts.

### **Conclusion & Recommendation**

The **BFO A5MLB3 4x Engine Transmission Pitch Mount** is a solid upgrade for **high-performance Subaru WRX/STI builds**, particularly those with significant power additions (turbocharged, supercharged, or engine swaps). It provides better structural integrity and reduces engine movement, which can prevent long-term damage to mounts, hoses, and wiring.

However, for **stock or mildly modified vehicles**, the benefits may not justify the trade-offs in vibration transfer and potential increased strain on other components. In these cases, a **high-quality rubber mount upgrade** (such as a **Subaru-specific rubber mount from a reputable brand**) might be a better choice, offering a balance between durability and comfort.

- You have a **high-power WRX/STI** (especially with forced induction).

- You ve noticed **excessive engine movement** or **worn stock mounts**.

- You re looking for **long-term durability** and **structural reinforcement**.

- Your vehicle is **stock or lightly modified**.

- You prioritize **comfort and vibration dampening** over stiffness.

- You re on a **tighter budget** and don t need the extra rigidity.

For best results, ensure proper installation and consider reinforcing the **firewall and transmission mounts** if your build is aggressive. Always consult with a trusted mechanic if you're unsure about compatibility with your specific setup.
