Product details


With a sports car-inspired appearance that shines behind open-spoke wheels, the StopTech Brake Kit - Drilled - Stage 1 Street Rotor and Pad Kit offers both form and function. You can choose from three different rotor options: a drilled brake kit that's built for high-performance street or track day use, a slotted brake kit that's meant for aggressive street or track day use, or a drilled and slotted brake kit that's designed for aggressive street driving. As an added benefit, the hat, cooling canes, and exterior edges of these full kits have been treated with black e-coating to prevent them from corrosion (standard on most rotors). When it comes to installing a StopTech Brake Kit, it is no different than any other brake job. Each component is custom-made for a factory fit, requiring no drilling, cutting, or welding to complete the assembly.
The best of both worlds, these StopTech Street Axle Packs feature cross-drilled StopTech Sport Rotors and StopTech Street pads for significantly improved performance with low dust and noise.
The StopTech Brake Kit - Drilled - Stage 1 Street Rotor and Pad Kit is a one-piece direct replacement brake disc that is designed to work with factory brake systems and stock calipers. In addition to providing significantly improved stopping performance, these discs look amazing behind your wheels. The one-of-a-kind cross-drilling and slotting not only helps disperse heat and brake dust, but also reduces the glazing of the pads, increases bite and improves the braking performance in both wet and dry conditions. The black e-coating provides protection against corrosion and the high carbon metallurgy (in most applications) delivers quiet operation, improved crack resistance, and enhanced performance in most cases.

This kit comes with StopTech black e-coated rotors, which provide improved cooling, shorter stops, and less fade, and StopTech Street Pads, which are designed for aggressive use on the street or track. The Stage 1 Street Rotor and Pad Kit provide significant improvements in braking performance while utilizing OEM-standard sized components, making them easy to install and the most effective in terms of performance.
