Detailed Product Description

The 830-47037L rotor from Dynamite Friction is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering reliable braking performance with enhanced heat management. The rotor’s vented design allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. The directional surface pattern, combining drilled holes and slots, aids in removing brake dust, gases, and water, which can improve pad contact and reduce brake fade.

Constructed with a plain disc finish and a Geospec silver grey hat finish, this rotor also features a rust resistant coating to protect against corrosion, extending the rotor’s service life. The rotor’s dimensions, including a 315.5 mm outside diameter and 42.8 mm overall height, are designed to meet OEM specifications for Chevrolet Cobalt and HHR models, ensuring proper fitment and performance.

Applications and Problem Solving

  • Replaces worn or warped rotors on Chevrolet Cobalt and HHR vehicles
  • Addresses brake fade caused by excessive heat during heavy braking
  • Improves braking response in wet or dusty conditions with slotted and drilled surface
  • Prevents rust and corrosion that can lead to rotor degradation
  • Restores proper rotor thickness and surface integrity for safe braking

Installation Notes and Tips

When installing the 830-47037L rotor, ensure the rotor is mounted with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify that the 5 bolt holes with 14.3 mm diameter align with the vehicle’s hub and that the 110 mm bolt circle diameter matches the wheel hub pattern. It is recommended to inspect brake pads and hardware during installation and replace if necessary to maintain optimal braking performance.
