Motorsport Brake Bias Valve Cost Comparison (AP Racing, Willwood & Tilton)
Why Brake Bias Matters in Racing
Brake bias is all about how the braking force is distributed between the front and rear wheels. Adjusting it can lead to sharper braking, improved corner stability, and better lap times. This adjustment is especially important as vehicle weight changes due to fuel consumption and varies with different track conditions.
Understanding brake bias is essential for competitive racing. A balanced brake system allows for aggressive cornering and reduces the risk of wheel lock-up, which is key for maintaining control during high-speed turns.
As fuel is consumed during a race, the car's weight distribution shifts. For example, a full tank might increase weight at the rear, making the car feel different under braking. By adjusting brake bias, drivers can compensate for these changes and maintain optimal performance throughout the race.
