This product line is designed to enhance braking efficiency and rotor longevity, making it suitable for vehicles like the Chevrolet Cobalt and HHR that require reliable and durable braking components.\u003c\/p\u003e\u003ch2\u003eTechnical Details and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The drilled and slotted surface improves water and gas evacuation, maintaining consistent contact between the brake pad and rotor. The rotor’s directional surface ensures proper alignment for optimal performance. With a nominal thickness of 25.7 mm and a discard thickness of 24 mm, this rotor meets precise wear limits for safety and reliability. The zinc silver coating on the hat area provides rust resistance, extending the rotor’s service life.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Chevrolet Cobalt and HHR models requiring vented disc brake rotors\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet conditions through directional drilled and slotted design\u003c\/li\u003e\n\u003cli\u003eReduces rotor surface corrosion with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eMaintains structural integrity with precise thickness specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface facing outward to maximize water and debris evacuation. Verify bolt hole alignment with the 5-lug, 110 mm bolt circle diameter pattern. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 24 mm. Proper torque specifications should be followed to avoid warping or uneven wear.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM standards for fit and function.
