Brakes are often the unsung heroes of automotive performance. Whether you're a weekend track enthusiast or a casual autocrosser, upgrading your braking system can yield significant performance gains.
When it comes to enhancing a car's performance, most people focus on engine tweaks, suspension adjustments, and wheel and tire modifications. However, one critical component that frequently gets overlooked is the braking system. I discovered this firsthand when I started autocrossing two years ago in my Subaru WRX.
The Subaru WRX is an excellent car for beginners in the racing world. Its turbocharged 4-cylinder boxer engine provides ample power for quick acceleration, and the all-wheel-drive (AWD) system helps maintain speed through corners. However, the WRX's stock brakes are a notable drawback, especially when compared to the 4-piston Brembo brakes found on its more powerful sibling, the STi.
After a few autocross events, it became clear that my WRX's stock brakes were not up to the task. They struggled to handle the intense demands of racing, leading to brake fade and a less responsive pedal feel. This prompted me to explore potential upgrades that would be effective for both racing and daily driving.
One of the first upgrades I made was replacing the stock rubber brake lines with stainless steel ones. Rubber brake lines can flex under pressure, resulting in a spongy brake pedal feel. Stainless steel lines, on the other hand, provide a more consistent and firm pedal response.
I also upgraded to a DOT5 racing brake fluid. Unlike standard brake fluids, DOT5 fluid has a higher boiling point, which helps prevent brake fade during intense driving sessions.
To improve initial bite and overall braking performance, I opted for Hawk HP brake pads. These pads are designed for performance street use and have received numerous positive reviews for their balance of daily drivability and track performance.
After installing these upgrades, the difference was immediately noticeable. The brake pedal felt much firmer, and the brakes were significantly more responsive. At my next autocross event, the improvements were evident in my lap times. The enhanced pedal feedback and higher friction brake pads allowed me to brake later, resulting in higher average lap speeds and slightly faster lap times. Importantly, I was able to complete all three laps without experiencing any brake fade, even when my tires were hot and sticky.
Upgrading your braking system can lead to substantial performance improvements. According to a study by Car and Driver, high-performance brake pads can reduce stopping distances by up to 20%. This can be the difference between winning and losing in a competitive racing environment.
Better brakes also enhance safety. The National Highway Traffic Safety Administration (NHTSA) reports that improved braking systems can reduce the risk of accidents by providing more reliable stopping power in emergency situations.
Upgrading your braking system is a crucial yet often overlooked aspect of automotive performance. Whether you're a weekend warrior or a daily driver, investing in better brakes can lead to significant improvements in both performance and safety. So, the next time you're looking to enhance your car's capabilities, don't forget to give your brakes the attention they deserve.
By focusing on these often-overlooked components, you can achieve faster lap times, better safety, and a more enjoyable driving experience.
