Brake Kits

Brake kits bundle rotors and pads into one package for a complete axle upgrade in a single purchase. Whether you need a stock replacement kit for a daily driver or a performance kit for spirited driving, a brake kit ensures matched components for consistent stopping power. Popular ProductsPopular brake kits include EBC Brakes GD sport kits, StopTech Sport axle packs, and Power Stop Z23 Evolution kits. These bundles pair slotted or drilled rotors with upgraded ceramic or metallic pads for improved heat dissipation and shorter stopping distances. What is the advantage of a brake kit over buying parts separately?Brake kits guarantee that the rotors and pads are matched by the same manufacturer for optimal compatibility. This avoids mixing brands that may have different bed-in requirements and ensures consistent pad-to-rotor contact. How do I bed in new brakes from a kit?The standard bedding procedure involves a series of moderate stops from 30 mph to 5 mph, followed by harder stops fro...

Brake Kits - Performance Slot

Performance slotted brake kits pair high-carbon slotted rotors with upgraded brake pads for improved braking under hard use. The slots evacuate gas, heat, and debris from the pad surface for consistent bite during spirited driving or towing. Popular ProductsTop slotted brake kit brands include EBC Brakes GD series, StopTech Sport Axle Pack, and Hawk Performance Sector 27. These kits are popular for towing vehicles, performance sedans, and trucks that see occasional track or canyon driving. What is the benefit of slotted rotors over stock?Slotted rotors channel gas and debris away from the pad-to-rotor contact surface, reducing brake fade under repeated hard stops. They also improve wet-weather braking by displacing water faster than a smooth rotor. Are slotted rotors louder than stock?Slotted rotors may produce a slight additional noise during light braking as the slots contact the pad edge. This is normal and typically diminishes after a brief break-in period. High-quality slotted ...
