The performance of brake pads is critical for any track enthusiast. Among the many options available, StopTech Street Performance and Ferodo DS2500 are two popular choices. This article focuses on a fade resistance test conducted on the track to compare these two brake pad options.
Understanding Fade Resistance
Fade resistance refers to the ability of brake pads to maintain their performance under extreme conditions. During heavy braking, brake pads can overheat, leading to reduced stopping power. This is a crucial factor for track performance, where repeated high-speed stops are common.
Brake Pad Specifications
- StopTech Street Performance: Designed for street and track use, offering a balance between performance and longevity.
- Ferodo DS2500: Known for its high friction characteristics and excellent modulation, making it a favorite among track enthusiasts.
Test Methodology
The fade resistance test involved a series of laps on a closed track, simulating conditions that would typically cause brake fade. Both brake pads were installed on identical vehicles to ensure a fair comparison.
Test Conditions
The test was conducted on a warm day, with ambient temperatures around 80°F. The track layout included a mix of high-speed straights and tight corners, providing ample opportunities for braking.
Data Collection
Data was collected using a performance data logger, which monitored brake temperatures, lap times, and deceleration rates throughout the test. Each brake pad was tested for a total of ten laps, with data recorded at the end of each lap.
Results
The results of the fade resistance test revealed significant differences between the two brake pads. Below are the key findings:
- StopTech Street Performance: Experienced noticeable fade after six laps, with brake temperatures reaching critical levels.
- Ferodo DS2500: Maintained consistent performance throughout the test, with minimal fade even after ten laps.
Analysis of Performance
The analysis of the data collected during the test provides insight into the performance characteristics of each brake pad.
Temperature Profiles
The temperature profiles indicated that the StopTech pads reached their maximum operating temperature much sooner than the Ferodo pads. This early peak contributed to the fade experienced during the test.
Lap Times
Lap times showed that the Ferodo DS2500 provided more consistent braking performance, allowing for faster lap times as the test progressed. In contrast, the StopTech pads demonstrated a decline in performance as fade set in.
Conclusion
In conclusion, the fade resistance test conducted on the track highlighted the differences between StopTech Street Performance and Ferodo DS2500 brake pads. While both pads have their merits, the Ferodo DS2500 proved to be superior in terms of fade resistance and overall performance during extended track use.
Recommendations
- If you frequently participate in track days, consider using Ferodo DS2500 for enhanced performance.
- For mixed-use applications, StopTech Street Performance may still be a viable option, particularly for street driving.
Further Research
Future tests could incorporate different track conditions and vehicle setups to provide a more comprehensive understanding of brake pad performance. Additionally, comparisons with other brake pad brands could yield valuable insights for enthusiasts.
