Wilwood Rotor-Steel-SSF Front 12.90 x .380 - 12 on 8.75in

Wilwood is well-known for making performance brake components for a wide range of motorsports. This front brake rotor, part number 160-4766, is a great example of their focus on durable, lightweight parts. It’s constructed from steel, which makes it a solid choice for applications where temperatures stay in the low to moderate range, with only occasional high heat spikes. Think of drag cars at the end of a run or stock cars coming in from a qualifier.

This rotor uses a special alloy and manufacturing process that helps it resist thermal distortion. That means it’s less likely to warp under stress, giving you consistent performance. It also offers good friction and wear characteristics when paired with brake pads. The rotor measures 12.90 inches in diameter and is 0.380 inches thick, with a 12 on 8.75-inch bolt pattern, making it suitable for lighter weight open-wheel cars and road racers.
