Product Details
The 380x34mm, two-piece rotors in this Brembo GT Big Brake Kit are cast from a high-carbon iron alloy, a material chosen for its ability to handle the heat generated during aggressive braking. This kit is built around a set of six-piston calipers, specifically the RZ34 model, which distribute clamping force evenly across the rotor surface. The calipers themselves are cast from aluminum for a good balance of strength and weight, and they come finished in a bright yellow to stand out.
This kit is designed for serious performance driving, where consistent stopping power under heavy load is critical. The drilled rotor faces help to dissipate heat and gasses, which can improve braking performance and reduce fade during repeated hard stops. Because this is a Big Brake Kit, it's a significant upgrade over stock components, offering a substantial increase in braking capacity. Installation will involve replacing your factory calipers, rotors, and potentially brake lines, so it's a job best suited for someone comfortable with brake system work or a professional mechanic.
When installing this kit, be sure to check the manufacturer's instructions for any specific requirements regarding brake line compatibility or caliper mounting. It's also a good idea to have fresh brake fluid on hand for bleeding the system after installation. This kit represents a major step up in braking performance for vehicles that demand it.
