Wilwood 140-17644-D ProMatrix Rear Drilled Rotor Upgrade Kit

The Wilwood 140-17644-D ProMatrix Rear Rotor Upgrade Kit is designed specifically for 2001-2005 Mazda Miata NB models equipped with sport suspension. This performance-oriented upgrade enhances braking capability while retaining your factory OE brake calipers, making it an ideal solution for enthusiasts seeking improved brake performance without a complete caliper replacement.

Key Features:

• Two-piece rotor design with lightweight aluminum hat assembly for reduced unsprung weight
• SRP drilled and slotted rotor faces for improved heat dissipation and pad cleaning
• Black e-coat finish provides superior corrosion resistance for street-driven vehicles
• ProMatrix brake pads included with dual-purpose street/track compound formulation
• Compatible with factory OE rear brake calipers and master cylinder
• Includes all necessary mounting hardware for direct bolt-on installation

This ProMatrix rotor upgrade delivers measurable improvements in brake response, fade resistance, and thermal management. The drilled and slotted rotor design helps evacuate gases and water while reducing pad glazing for consistent pedal feel. The black e-coat finish not only provides a high-tech appearance but also protects against rust and corrosion in daily driving conditions. Perfect for sport driving enthusiasts who demand better braking performance from their Miata.
