What is the benefit of a 2-piece rotor design?

A 2-piece rotor design separates the rotor ring from the hat. This can reduce overall weight and make it easier to replace just the rotor ring if it wears out, rather than the entire assembly.

What does 'SRP' mean for this rotor?

SRP stands for Spec 37, which is Wilwood's proprietary iron alloy. This material is chosen for its strength and ability to handle heat without deforming, which is crucial for consistent braking performance.

What is the purpose of the drilling and slotting on this rotor?

The drilled holes help to dissipate heat away from the rotor surface, preventing it from getting too hot. The slots help to sweep away brake pad dust and gases that can build up between the pad and rotor, ensuring better contact and more consistent stopping power.

Product Details

Wilwood is well-known for making high-performance braking components, and this 1219-081CJ306-232MNEXXXXR rotor is a great example of their focus on stopping power. This is a 2-piece rotor design, which means the rotor ring and the hat are separate pieces. This design helps reduce weight and can also make replacement easier if only the rotor ring wears out.

This specific rotor features a black hat, giving it a clean look behind the wheel. The rotor itself is an SRP (Spec 37) casting, which is a proprietary iron alloy Wilwood uses for its strength and thermal stability. It's drilled and slotted, meaning it has holes and grooves machined into the surface. The drilling helps with cooling, while the slots help clear out dust and gas that can build up between the pad and rotor during hard braking. This combination helps maintain consistent stopping performance, especially under demanding conditions.

This rotor is designed with a 5x4.50/5.50 bolt pattern for the hat, and it's a direct-drive (D/D) style, meaning it mounts directly to the hub assembly. If you're looking to upgrade your braking system with a well-built, performance-oriented rotor, this Wilwood piece is a solid option.
