2. Advantages for G3500 Geomet brake rotor :
*High carbon alloy proveides durability and strength at high temperatures.
*Manufactured to G3500B, the highest materail standard in the industry , for better heat dissipation to eliminate brake fade and have longer pad life.
*Tighter tolorance for Runout and balance leads to longer service life and improved performance .
*Geomet coated and salt spray tested to 400 hours.
