UM NASCAR Cup Series

The NASCAR Cup Series Gen 6 features a powerful but nuanced braking system that demands careful setup work. Brake bias is your primary tuning tool—values above 50% send more pressure to the front wheels, while lower values shift braking force rearward. This adjustment should be matched to both track characteristics and driving style, as the car's behavior under braking directly influences entry stability and rotation.

The truck arm mounting system plays a critical role in braking performance. Higher truck arm mounts reduce wheel hop under heavy braking by adding anti-squat, though they sacrifice rear grip. Lower mounts increase rear bite and stability but can trigger wheel hop on aggressive brake applications. This trade-off becomes especially important on road courses where heavy braking zones demand consistent, predictable deceleration.

Camber settings affect longitudinal grip during braking—higher camber angles improve cornering but reduce straight-line braking traction. Finding the right balance prevents premature lock-ups while maintaining the tire contact patch you need through corner entry. Monitor tire temperatures across the tread surface to verify your camber isn't compromising braking performance for corner speed.
