Construction & Design:

The Stoptech Big Brake Kit is built with premium materials and advanced engineering to ensure exceptional performance and reliability. The rotors feature a unique directional vane design combined with lightweight 7075 T-6 billet aluminum hats, which significantly improve cooling efficiency and reduce unsprung weight. This design helps prevent brake fade during aggressive driving or track use.

The ST-40 calipers are crafted from high-strength aluminum and incorporate a bolt-in bridge to enhance structural rigidity. This design minimizes caliper flex and distortion, ensuring consistent pad contact and braking force. The calipers also include integral air channels to aid in cooling, further enhancing performance under demanding conditions.

Installation & Fitment:
