Construction & Design

The Brembo GTR system features monobloc calipers machined from a single billet of cast aluminum, providing unmatched stiffness and resistance to flex under heavy braking. This design ensures consistent pad contact and improved pedal feel. The rotors are constructed from an advanced high-carbon alloy with corrosion-resistant plating, enhancing durability and performance longevity.

The two-piece floating rotor design incorporates a curved 48-vane venting system that maximizes airflow and cooling efficiency. This reduces brake fade and extends component life during aggressive driving or off-road use. The slotted and cross-drilled rotor surfaces not only improve heat dissipation but also help maintain clean pad surfaces for reliable stopping power in all conditions.
