Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted from Dynamite Friction is specifically designed for Subaru Impreza, WRX, and WRX STI vehicles requiring reliable and consistent braking performance. This rotor features a vented design that helps dissipate heat more effectively during heavy braking, reducing the risk of brake fade. The directional slotted and drilled surface improves water and debris evacuation, maintaining optimal contact between the brake pad and rotor surface. The rotor’s plain disc finish combined with a Geospec silver grey hat finish provides corrosion resistance and a clean appearance. Additionally, the rust resistant coating further protects the rotor from environmental damage, extending its service life.

The rotor’s dimensions, including a 326 mm outside diameter and 53.1 mm height, ensure proper fitment and compatibility with the specified Subaru models. The 5 bolt holes with a 12.9 mm diameter and 114.3 mm bolt circle diameter match factory specifications for secure installation. The nominal thickness of 30 mm and discard thickness of 28 mm provide a clear service limit for maintenance.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

Installation Notes and Tips

Ensure the rotor is compatible with your Subaru Impreza, WRX, or WRX STI before installation. Verify the bolt hole pattern (5 holes, 12.9 mm diameter, 114.3 mm bolt circle) matches your vehicle’s hub. Clean the rotor surface of any protective coatings or oils before mounting to ensure proper brake pad contact. Follow manufacturer torque specifications for lug nuts to avoid rotor damage or uneven wear.
