• Diameter: 14.00 inch
• Thickness: 1.25 inch
• Mounting: 12 bolt on an 8.75 inch bolt circle
• 72 curved vane internal ventilation
• Spec-37 proprietary iron alloy
• GT Series asymmetrical face slot pattern
• Side: Left Hand (directional, order the matching opposite side)
• Individually dynamically balanced

Fitment: This is a component rotor for a two-piece assembly, not a vehicle-specific replacement. Confirm fitment by hat bolt pattern, diameter, thickness, and caliper offset before ordering.

Spec-37 alloy was developed from Wilwood's extreme duty military rotor work and resists distortion, warping, and cracking at temperatures that crack ordinary iron. The curved vanes pump air outward as the rotor turns, so heat leaves the disc instead of soaking into the hub and pads.
