Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented design to improve airflow and reduce heat buildup during braking. The rotor features a drilled and slotted surface type, which helps evacuate gases, dust, and water, maintaining consistent brake pad contact. The directional surface ensures proper rotation alignment for optimal braking efficiency.

The rotor's nominal thickness is 24 mm, with a discard thickness of 22 mm, indicating when replacement is necessary to maintain safety. The hat finish is zinc silver coated, providing corrosion resistance, complemented by an overall rust-resistant coating on the rotor. The bolt hole diameter is 13 mm with five bolt holes, matching a bolt circle diameter of 100 mm. The center hole diameter measures 58 mm, and stud/lug holes are sized at 12.7 mm with a quantity of five, ensuring compatibility with specified vehicle models.

Compatible Vehicles and Applications

This rotor is compatible with various Scion, Subaru, and Toyota models, including:

• Scion FR-S and Toyota 86/GR86
• Subaru BRZ
• Subaru Baja, Crosstrek, Forester, Impreza, Legacy, Outback, WRX, and XV Crosstrek
