The Subaru STI is renowned for its performance and handling capabilities. However, many enthusiasts seek to enhance these attributes further through differential upgrades. One popular choice among Subaru owners is the Wavetrac differential, particularly when compared to the vsMFactory options. In this article, we will explore owner reviews of these differential upgrades and determine whether they are worth the investment.
Understanding Differential Upgrades
A differential plays a crucial role in a vehicle’s performance, especially in high-performance models like the Subaru STI. It allows the wheels to rotate at different speeds, which is essential for cornering. Upgrading the differential can lead to improved traction, handling, and overall driving experience.
What is the Wavetrac Differential?
The Wavetrac differential is designed to provide superior traction and handling. It features a unique design that allows for torque biasing, which means it can send power to the wheel with the most grip. This feature is particularly beneficial in challenging driving conditions, such as wet or snowy roads.
What is the vsMFactory Differential?
The vsMFactory differential is another popular option among Subaru enthusiasts. It is known for its robust construction and performance-oriented design. The vsMFactory differential aims to provide a balance between daily drivability and performance, making it a versatile choice for many drivers.
Owner Reviews: Wavetrac vs vsMFactory
To understand the real-world performance of these differential upgrades, we gathered reviews from Subaru STI owners who have installed either the Wavetrac or vsMFactory differentials. Here’s what they had to say:
- Wavetrac Owners: Many owners reported a noticeable improvement in traction, especially during hard cornering. They praised the differential for its ability to handle power effectively, even in adverse weather conditions.
- vsMFactory Owners: Owners highlighted the durability of the vsMFactory differential. They appreciated its performance on both the street and the track, noting that it provided a balanced feel without sacrificing daily drivability.
Performance Comparisons
When comparing the performance of the Wavetrac and vsMFactory differentials, several factors come into play:
- Traction: The Wavetrac differential is often favored for its superior traction capabilities, particularly in slippery conditions.
- Handling: Both differentials improve handling, but Wavetrac owners frequently note a more responsive feel during aggressive driving.
- Noise Levels: vsMFactory owners report a quieter operation, making it more suitable for daily driving.
- Installation: The installation process for both differentials is similar, but some owners found the Wavetrac easier to install due to its design.
Cost Considerations
Cost is a significant factor when considering differential upgrades. Here’s a breakdown of the price range for both options:
- Wavetrac Differential: Prices typically range from $1,200 to $1,800, depending on the specific model and features.
- vsMFactory Differential: This option generally costs between $1,000 and $1,500, making it a slightly more affordable choice for budget-conscious enthusiasts.
Final Thoughts: Are Differential Upgrades Worth It?
Ultimately, whether differential upgrades are worth it depends on your driving style and goals for your Subaru STI. Here are some key takeaways:
- If you prioritize traction and performance, the Wavetrac differential may be the better choice.
- If you seek a balance of performance and daily drivability, the vsMFactory differential could be ideal.
- Consider your budget and how much you are willing to invest in your vehicle’s performance.
Both the Wavetrac and vsMFactory differentials have their strengths, and owner reviews highlight the benefits of each. Ultimately, the decision should align with your personal driving preferences and performance goals.
