Building a drift car is an exciting journey, especially when it comes to the Subaru BRZ. Among the many components that require attention, brake bias and the cooling system are critical to ensuring optimal performance on the track. This article outlines the essentials for preparing your BRZ drift build, focusing on these two key areas.
Understanding Brake Bias
Brake bias refers to the distribution of braking force between the front and rear wheels. In a drift scenario, achieving the right brake bias is crucial for maintaining control and stability. Too much front bias can lead to understeer, while too much rear bias can cause oversteer.
Factors Influencing Brake Bias
- Weight Distribution: The BRZ has a near 50/50 weight distribution, which affects how braking forces are applied.
- Tire Grip: The type and condition of your tires will influence how much braking force each axle can handle.
- Suspension Setup: Your suspension geometry can affect the load on each wheel during braking.
Adjusting Brake Bias
To adjust brake bias, you can use various methods, including brake proportioning valves, adjustable master cylinders, or even changing brake pad compounds. Each method has its pros and cons, and understanding these will help you make informed decisions.
Brake Proportioning Valve
A brake proportioning valve allows you to adjust the pressure that is sent to the rear brakes. This is particularly useful in a drift setup, as it can help fine-tune the balance between the front and rear wheels.
Adjustable Master Cylinder
Using an adjustable master cylinder can provide more control over brake bias. This option is typically more complex but allows for precise adjustments based on your driving style and track conditions.
Cooling System Essentials
Drifting can put a significant strain on your vehicle’s cooling system. Overheating can lead to performance loss and damage, making it essential to ensure your cooling system is up to the task.
Upgrading Your Radiator
An upgraded radiator can significantly improve cooling efficiency. Look for options that provide increased surface area and better airflow, which are crucial for high-performance applications like drifting.
Adding an Oil Cooler
An oil cooler can help maintain optimal oil temperatures, which is vital for engine performance. Ensuring that your oil remains within the ideal temperature range will help prevent engine wear and extend its life.
Upgrading Coolant
Using high-performance coolant can enhance your cooling system’s effectiveness. Look for coolants that offer better heat transfer and are designed for high-stress applications.
Conclusion
Preparing your BRZ for drifting involves careful consideration of both brake bias and the cooling system. By understanding how to adjust brake bias and ensuring your cooling system is up to par, you can enhance your drift build’s performance and reliability on the track.
