Kia Optima K5 sports hoods Korean-made front and rear set perforated and punched (2012-2024)

These sports brake discs of Korean manufacturing are the perfect upgrade for Kia Optima and K5 cars to ensure strong and smooth braking. This front and rear set is made of heat-treated carbon metals according to Korean standards, where the design of the geometric holes immediately disperses heat and hot gases, ensuring the brake system remains cool and stable even during sporty driving. Insulation and protection technology: The discs are equipped with advanced insulation technology that protects the metal parts from corrosion and rust, ensuring long-term maintenance of mechanical performance efficiency and a clean sporty appearance behind your car rims. Laser balancing: Each disc is precisely checked and weighed with laser to ensure 100% balanced rotation, which is very necessary to maintain cabin quietness and prevent any steering vibrations at high speeds. Performance in harsh conditions (Why Korean discs for the K5 Optima?): Super cooling for turbo and GDI engines: Modern Kia engines generate power that requires high-performance braking; drilling provides 35% faster cooling, preventing brake fade on highways. Response in traffic: The holes continuously ventilate the disc surface, preventing the formation of a glaze layer caused by heat, and maintaining a "strong pedal" feel and immediate braking response in city streets. Water and dirt drainage: The hole design ensures immediate expulsion of water and debris from between the disc and pad, enhancing braking strength and providing greater safety in rainy weather. Brake problem solutions guide (Why do you hear noises?): Squealing noise: Usually caused by pad overheating and surface burning; sports holes provide ventilation that prevents pads from reaching burning temperatures that cause noise. Grinding noise: A metallic sound indicates the friction material has worn out; using the included ceramic pads guarantees silent braking and smoothness. Vibration: A common problem caused by warping original discs due to heat; the processed Korean metal resists warping superbly and is unaffected by sudden water cooling during car wash. Professional installation instructions: Direction basis: To ensure the internal cooling turbine works correctly, install according to the labels: (R-Right): Passenger side. (L-Left): Driver side. Cleaning before starting: Clean the disc surface with Brake Cleaner to remove any oil layer, ensuring the pad bonds directly and effectively from the first touch. Compatibility and exclusive gift: Cars: Kia Optima and Kia K5 in all variants — models from 2012 to 2024. Exclusive offer: Front and rear disc set + high-quality ceramic pad set free with every order to ensure a complete, quiet, and clean braking system. Frequently Asked Questions: Where are these discs made? These discs are high-quality Korean-made, specifically designed to match Kia’s technical specifications. Do they fit original rims? Yes, designed with original factory sizes and fit directly without any mechanical modifications (Plug & Play). Do they cause blackening on the rims? The gift ceramic pads produce much less dust, helping keep your rims clean. Why are the discs drilled only? The perforated design provides optimal cooling and reduces disc weight, making it the best solution for daily and balanced sporty use. What is the warranty? A golden 6-month warranty against cracking or vibration to guarantee your right to quality and performance.
