.625 Hawk Dynalite with Bridgebolt NDL DTC-05 brake pads are designed for lower temperature dirt circle track applications. These pads provide lower predictable and controllable torque. Great for use on high momentum race tracks where a high torque level is not needed. They fit Wilwood with bridge bolt, Outlaw, and Sierra. Optimal temperature range: 100 to 900 degrees F (38 to 482 degrees C).
