Product Line Details: StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to offer enhanced braking performance through improved heat management and durability. The cross-drilled surface pattern helps dissipate heat and gases generated during braking, which can improve pedal feel and reduce the risk of brake fade. This rotor is solid rather than vented, providing a consistent braking surface optimized for street and light performance use. The coated hat finish adds corrosion resistance, extending rotor life in various driving conditions.

Technical Specifications and Fitment

This rotor is specifically compatible with Kia models including the Forte, Forte5, Forte Koup, and Soul. It features a solid disc design with a nominal thickness of 0.394 inches (10.000 mm) and a discard thickness of 0.331 inches (8.400 mm), ensuring safe replacement intervals. The rotor’s outside diameter measures 10.315 inches (262.000 mm), and it mounts using five lug holes spaced on a 4.500 inch (114.300 mm) bolt circle diameter. The center hole diameter is 2.992 inches (76.000 mm), matching OEM specifications for proper fitment. This part number 128.50027R is engineered to meet or exceed factory standards for these Kia vehicles.
