Wilwood 160-8398-GTB is a GT series right hand brake rotor with a 72 curved vane Spec-37 iron casting and a black finish.

Specifications

• GT series curved vane rotor with 72 vanes
• 12 x 8.75 in bolt circle
• Spec-37 iron casting
• Black finish
• Sold individually (one rotor)
• Right hand rotor - order the matching left hand rotor separately for a pair

Curved vane rotors are handed, so the left and right castings are not interchangeable and must be fitted on the correct corner for the vanes to pump cooling air outward. This rotor is the right hand side; order the matching left hand casting for a complete axle. The Spec-37 iron used in the casting is Wilwood's own high-carbon alloy, chosen for its resistance to heat checking and its stability under repeated hard stops. Rotors are sold individually.

The source data for this part lists only the part number and casting specifications, with no vehicle application and no further description. Confirm fitment by rotor diameter, thickness, and bolt pattern before ordering.
