Why Upgrade Your Brakes?
Factory brakes are designed to meet baseline safety standards at stock power levels. Once you've added power modifications, stickier tires, or started attending track events, the limitations become clear—brake fade under repeated hard stops, spongy pedal feel as temperatures climb, and longer stopping distances when you need them shortest. A performance brake upgrade kit addresses these issues with components engineered specifically for high-demand driving.
What's Included in a Brake Upgrade Kit
Complete brake upgrade kits typically include larger diameter rotors that increase thermal mass and heat dissipation, multi-piston fixed calipers that provide more even pad pressure and improved modulation, high-temperature brake pads matched to the system, stainless steel braided brake lines for firmer pedal feel, and all necessary mounting hardware and brackets. Some kits also include performance brake fluid rated for higher boiling points.
Benefits of Big Brake Kits
Larger rotors and calipers deliver several key advantages. Increased rotor diameter provides greater leverage for the caliper, reducing the effort needed to slow the vehicle. Greater thermal mass absorbs more heat before temperatures affect performance, resisting brake fade during repeated heavy braking. Multi-piston calipers apply force more evenly across the pad surface, improving modulation and reducing uneven pad wear. The result is shorter stopping distances, more consistent pedal feel, and the ability to brake later and harder—lap after lap.
Street vs. Track Considerations
Brake upgrade kits are available in configurations suited for different uses. Street-focused kits prioritize low noise, minimal dust, and good cold bite for daily driving with occasional spirited use. Track-oriented kits use more aggressive pad compounds and slotted or drilled rotors designed for repeated high-temperature cycles. Many enthusiasts choose kits that balance both requirements, swapping pad compounds between street and track duty while keeping the same calipers and rotors.
Fitment and Compatibility
Big brake kits require adequate wheel clearance—larger calipers may not fit behind factory wheels. Always verify minimum wheel diameter and spoke clearance before purchasing. Most kits are designed for direct bolt-on installation using existing mounting points, though some may require minor modifications or specific wheel offsets. Our product listings include detailed fitment information and wheel clearance specifications for each kit.
