The Subaru WRX is a beloved vehicle among car enthusiasts, known for its performance and rally heritage. One popular modification among WRX owners is upgrading to larger wheels, particularly the 19-inch BBS wheels. This article explores the real-world results of fitting 19-inch BBS wheels on a Subaru WRX, specifically focusing on the reported 30 horsepower increase.
Understanding Wheel Fitment
Wheel fitment plays a crucial role in a vehicle’s performance. When upgrading to larger wheels, several factors come into play, including weight, size, and design. The BBS wheels are renowned for their lightweight construction and aesthetic appeal, making them a popular choice for performance upgrades.
Benefits of 19-Inch BBS Wheels
Switching to 19-inch BBS wheels can provide several advantages for Subaru WRX owners. Here are some key benefits:
- Weight Reduction: BBS wheels are designed to be lightweight, which helps improve acceleration and handling.
- Aesthetic Appeal: The sleek design of BBS wheels enhances the overall look of the WRX.
- Improved Traction: Larger wheels can accommodate wider tires, providing better grip on the road.
- Enhanced Performance: The combination of weight reduction and improved traction can lead to noticeable performance gains.
Real-World Testing
To validate the claims of a 30 horsepower increase, real-world testing was conducted on a Subaru WRX fitted with 19-inch BBS wheels. The testing involved a series of controlled runs to measure horsepower output before and after the wheel upgrade.
Initial Setup
The initial setup included a stock Subaru WRX with factory wheels and tires. Baseline horsepower measurements were taken using a dynamometer to establish a reference point for performance.
Wheel Installation
After obtaining baseline measurements, the stock wheels were replaced with 19-inch BBS wheels. The installation process was straightforward, ensuring that all components were properly fitted and torqued to specification.
Post-Installation Testing
Once the BBS wheels were installed, another series of dynamometer tests were conducted. The results were compared to the initial baseline measurements to assess any changes in horsepower output.
Results of the Testing
The results of the testing were impressive. The Subaru WRX showed a documented increase of 30 horsepower after the installation of the 19-inch BBS wheels. This increase can be attributed to the factors mentioned earlier, including weight reduction and improved traction.
Factors Influencing Performance
While the horsepower increase is significant, several factors can influence the performance of the vehicle:
- Tire Selection: The type of tires mounted on the BBS wheels can greatly affect performance.
- Suspension Setup: Upgrading suspension components may enhance handling and stability.
- Engine Tuning: Proper tuning can maximize the benefits of the wheel upgrade.
- Driving Conditions: Environmental factors such as road surface and weather can impact performance results.
Conclusion
Upgrading to 19-inch BBS wheels on a Subaru WRX can yield impressive real-world results, including a 30 horsepower increase. This modification not only enhances performance but also improves the aesthetic appeal of the vehicle. For WRX enthusiasts looking to boost their car’s capabilities, investing in high-quality wheels like BBS is a worthwhile consideration.
Further Considerations
Before making any modifications to your Subaru WRX, it’s essential to consider the following:
- Budget: Ensure you have a budget that accommodates the cost of wheels, tires, and any additional modifications.
- Compatibility: Verify that the wheels are compatible with your specific WRX model and year.
- Professional Installation: Consider having the wheels installed by a professional to ensure optimal performance and safety.
