Our rotors are designed to enhance braking performance compared to stock options, offering a more responsive feel which can reduce brake fade during demanding driving.
The key to this improvement is a larger diameter design, which increases the overall surface area for better heat dissipation. This upgrade is particularly attractive as it retains your stock calipers (unless mentioned otherwise), keeping the cost down while providing a noticeable improvement in braking performance.
Our vane design compliments on both structural integrity and heat dissipation. We’ve positioned our vanes to disrupt airflow across the rotor surface, breaking up the boundary layer of hot air. This turbulence promotes efficient heat transfer which reduces brake fade and ensures the drives has consistent stopping power.
Our rotors feature a custom slot design that’s consistent across our entire range, ensuring a uniform look and optimal performance on all fronts. Slots actively channel away heat, debris, and gasses from the braking surface.
