Detailed Product Description

This Dynamite Friction rotor features a solid disc design with a drilled and slotted surface type, which helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The rotor’s zinc silver hat finish and rust resistant coating provide enhanced protection against corrosion, making it suitable for long-term use in various driving conditions. With a nominal thickness of 9 mm and a discard thickness of 7.5 mm, this rotor maintains structural integrity and safety throughout its service life. The directional surface design ensures optimal contact with brake pads, improving stopping power and pedal feel.

The rotor is compatible with vehicles including the Pontiac Vibe and Toyota models such as the Celica, Corolla, Matrix, and tC, making it a practical replacement option for these applications. The 5-bolt hole pattern with a 100 mm bolt circle diameter matches factory specifications for secure mounting.

Applications and Problem Solving

• Replaces worn or warped rotors on compatible Pontiac and Toyota vehicles
• Addresses brake fade caused by overheating during aggressive or frequent braking
• Improves braking performance in wet or debris-prone environments with drilled and slotted design
• Prevents rust and corrosion-related rotor degradation
• Restores proper rotor thickness and surface condition for consistent braking

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (7.5 mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven wear or vibration
• Use proper torque specifications for the 5-bolt mounting pattern (100 mm bolt circle diameter)
• Check compatibility with vehicle make and model before installation
• Inspect brake pads for wear and replace if necessary to maximize rotor performance
