R1 Concepts Disc Brake Rotor Set Fits BMW Z3

This R1 Concepts Brake Kit is a complete all-in-one replacement that includes four high-performance brake rotors made from G3000 grade cast iron with rust protection, designed to meet OEM specifications. The rotors feature precision-drilled holes and a countersunk design to prevent cracking and buildup, improve ventilation, and dissipate heat, ensuring smoother, quieter, and more consistent braking performance. The diamond-slotted design enhances brake pad bite, extends pad life, and acts as a wear indicator. Manufactured with multiple alloys for improved heat dissipation and performance, these rotors are mill-balanced for proper function and validated for metallurgy and correct brake plate thickness.
