Product Details
SP Performance Double Drilled & Slotted Rotors offer maximum cooling and cleaning power for high-performance braking.
Dual sets of precision-drilled holes enhance airflow and heat dissipation, while machined slots remove brake dust, gases, and water for cleaner, more consistent contact.
Crafted from premium materials, these rotors are designed to reduce heat buildup, resist warping, and deliver reliable stopping power under extreme conditions.
The slotted design also helps prevent hydroplaning by channeling water away from the braking surface-enhancing safety in wet environments.
Each rotor is precision-drilled with SP Performance's exclusive Sinusoid Curve Chamfer, which increases air circulation, eliminates sharp edges, and minimizes rotor stress.
This reduces the risk of heat checking, cracking, and warping, while extending the life of both the rotor and brake pads.

    Ordered Enkei brand hubcentric rings, company sends Coyote brand hubcentric rings. Will they work, yes but it's a classic bait-n-switch sales tactic. Wish THMotorsports was upfront & honest with their customers.
