Is it better to buy new rotors or turn old ones?

Whether to buy new rotors or turn old ones depends on their condition. If the old rotors are thick enough, free of cracks, and within the minimum thickness specifications, turning them can be a cost-effective option. However, if they show signs of significant wear, warping, or damage, it's advisable to invest in new rotors for optimal performance and safety. New rotors often provide better braking efficiency and longevity.
