DTCC-70 & DTC-60 Brake Pad Compatibility

When delving into the world of high-performance braking systems, understanding the intricate relationships between different pad compounds and their optimal applications is crucial. This guide focuses on the compatibility of rotor pads with the widely respected DTC-70 brake pad compound. We'll explore how the DTC-60 compound complements the DTC-70, particularly in scenarios demanding exceptional braking power and control.

Understanding the DTC-70 Brake Pad

The DTC-70 is a renowned brake pad compound favoured by many in motorsport and performance driving circles. It's engineered to deliver consistent and powerful braking even under the most demanding conditions. Key characteristics often associated with the DTC-70 include its high friction coefficient, excellent thermal stability, and a progressive feel that allows drivers to precisely modulate brake pressure. This makes it a popular choice for track days, racing, and spirited road driving where stopping power is paramount.

Introducing the DTC-60 Brake Pad

The DTC-60, on the other hand, is designed to excel in situations that push the boundaries of braking performance even further. Hawk, the manufacturer, specifically recommends the DTC-60 to be paired with the DTC-70 when a split friction strategy is desired. This means using different friction materials on the front and rear axles to optimise the vehicle's braking balance and stability. The DTC-60 is known for its excellent modulation and release characteristics, which are vital for maintaining control during extreme deceleration events and when dealing with increased downforce, often encountered in high-speed racing scenarios.

DTC-70 and DTC-60: A Synergistic Pairing

The question of which rotor pads are compatible with DTC-70 often leads to the discussion of the DTC-60. Their compatibility is not just about fitting them onto the same caliper; it's about their engineered synergy. When used together, the DTC-70 and DTC-60 can offer a sophisticated braking solution.

Why Pair DTC-70 with DTC-60?

• Split Friction: The primary reason for pairing these two compounds is to achieve a split friction setup. This involves using a more aggressive or higher-friction compound on one axle (often the front, where most braking forces are initially applied) and a slightly less aggressive but still high-performance compound on the other.
• Braking Balance: By strategically using DTC-70 on one axle and DTC-60 on the other, tuners can fine-tune the vehicle's braking balance. This can help prevent premature lock-up of either the front or rear wheels, leading to more effective and stable deceleration.
• Modulation and Release: The DTC-60's excellent modulation and release characteristics can be particularly beneficial on the rear axle. This allows the driver to better manage the rear brakes, preventing oversteer caused by excessive rear braking, especially under heavy load or during corner entry.
• High Deceleration Rates: In applications with extremely high deceleration rates, the combined performance of these pads can offer a significant advantage. The DTC-70 provides immense stopping power, while the DTC-60 ensures that this power is applied in a controlled and predictable manner.
• Increased Downforce: Vehicles experiencing increased downforce, such as those in formula racing or high-speed prototypes, require braking systems that can cope with the additional forces acting upon them. The DTC-60's design is specifically suited to these demanding conditions, making it a logical partner for the DTC-70 in such applications.

Factors to Consider When Choosing Brake Pads

While the DTC-70 and DTC-60 are designed to work well together, several other factors influence the overall effectiveness of your braking system:

Rotor Material and Condition

The type and condition of your brake rotors are just as important as the pads. High-performance pads like the DTC-70 and DTC-60 are best paired with high-quality, heat-treated rotors. Ensure your rotors are free from warping, excessive wear, or glazing, as this can significantly compromise braking performance and pad life.

Brake Fluid

Using a high-quality, high-temperature brake fluid (e.g., DOT 4 or DOT 5.1) is essential. During intense braking, the fluid can reach high temperatures, and a fluid with a low boiling point can lead to brake fade. A good brake fluid ensures that the hydraulic system remains responsive under extreme heat.

Brake Cooling

For prolonged or extremely demanding use, effective brake cooling is vital. This can involve brake ducts that channel airflow to the rotors and calipers. Proper cooling prevents the brake system from overheating, which can lead to a loss of braking performance and damage to components.

Driving Style and Conditions

Your intended use case plays a significant role. Are you primarily using your vehicle for track days, autocross, or spirited road driving? The DTC-70 and DTC-60 are performance-oriented and may not be ideal for daily commuting due to potential for increased noise, dust, and wear on street-biased rotors. Understanding your driving style will help you select the most appropriate compound and configuration.

Frequently Asked Questions

Q1: Can I use DTC-70 on all four wheels?

A1: While you can technically use DTC-70 on all four wheels, Hawk specifically recommends pairing it with DTC-60 for a split friction setup when seeking optimised braking balance in demanding applications. Using DTC-70 on all four wheels might result in a very aggressive initial bite that could be challenging to manage for some drivers, especially on the rear axle.

Q2: Is the DTC-60 a good choice for street use?

A2: The DTC-60, much like the DTC-70, is a high-performance racing compound. It is generally not recommended for daily street use due to its tendency to produce significant brake dust, potential for noise, and aggressive wear characteristics on street-oriented rotors. These pads are designed for track environments where performance outweighs comfort and longevity under normal driving conditions.

Q3: How do I know if my car needs a split friction setup?

A3: A split friction setup is typically considered for vehicles used in performance driving or racing where fine-tuning of braking balance is critical. If you experience issues like premature rear wheel lock-up, understeer during braking, or inconsistent brake feel, a split friction setup with compounds like DTC-70 and DTC-60 might be beneficial. Consulting with a brake specialist or experienced performance tuner is advisable to determine if this is the right approach for your specific vehicle and driving needs.

Q4: What are the benefits of improved modulation and release?

A4: Improved modulation refers to the ease with which you can control the brake pressure, allowing for smoother and more precise application and release of the brakes. Better release characteristics mean the brakes disengage more cleanly and quickly when you ease off the pedal. Together, these qualities enhance driver confidence and control, especially in dynamic driving situations where subtle brake adjustments are often required.

Conclusion

In summary, when seeking rotor pads compatible with the DTC-70, the DTC-60 stands out as a highly recommended partner, particularly for those aiming for a sophisticated split friction braking strategy. This pairing is designed to handle extreme deceleration rates and increased downforce, offering enhanced braking balance, modulation, and control. While these compounds deliver exceptional performance, remember that a complete braking system upgrade involves considering rotors, fluid, and cooling. Always ensure your chosen components are suited to your driving environment and consult with experts when making performance-critical decisions.
