ECS Tuning Rear V4 Cross Drilled & Slotted Brake Rotors - Pair (330x22)

After 15+ years of ECS Brake Rotors, we are proud to offer our fourth iteration of rotors. We are proud to offer our V4 Rotors in Plain, Drilled, Slotted, and Drilled & Slotted Varieties - whether your car spends most of its time in city traffic or hitting the apex, there is an ECS V4 Rotor to suit your needs. ECS V4 Brake Rotors are Electrostatic Coated to prevent rust more effectively than the typical phosphate finishes used by other manufacturers. Oftentimes these phosphate coatings are only preventative during shipping and storage, resulting in immediate visible corrosion once exposed to heat and moisture on your vehicle. Our Electrostatic Coating is tested to endure 400 hours of salt spray exposure without rusting - we did this to save you the headache that comes from both the unappealing aesthetic of rusty rotors and associated run out issues. ECS V4 Rotors have a beautiful, fully machined finish - we fully machine our rotors to promote superior rotor balance and to give your car an attractive rotor that peeks out from behind your beloved wheels. Our V4 Rotors are designed to have a double disc ground, taper free finish - this prevents run out through guaranteed parallelism and accurate disc thickness variation (DTV). This process prevents the finish from being directional, facilitating a more effective pad and rotor break in period, along with smooth, silent stopping power for the life of the rotors.  ECS V4 Cross Drilled and Slotted rotors will give your vehicle track appeal, complimenting the rest of your wheel and suspension setup. Slotted rotors are designed to prevent brake dust and debris buildup from inhibiting performance, giving you more consistent brake feel. Cross drilled rotors keep your braking system cooler, thus reducing brake fade. Combining both cross drilled and slotted rotor types gives you more reliable performance whether you're in stop-and-go traffic or driving in wet road conditions. We carefully control the cooling rate during our manufacturing process to ensure that our drilled and slotted rotors meet or exceed tensile strength requirements. Additionally, our V4 Cross Drilled and Slotted Rotors are designed independently for the left and right side of your vehicle, ensuring that our drilled holes do not touch cooling vanes. Features:
