This product line emphasizes vented rotor designs to improve heat dissipation during braking, reducing the risk of warping and maintaining consistent stopping power. The smooth surface finish supports even pad wear and quiet operation, making it suitable for daily driving conditions on compatible Saab and Saturn models.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that allows air to flow between the rotor surfaces, effectively dissipating heat generated during braking. The nominal thickness of 0.984 inches (25.0 mm) ensures sufficient material for durability, while the discard thickness of 0.906 inches (23.0 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s outside diameter of 11.339 inches (288.0 mm) and overall height of 1.654 inches (42.0 mm) are engineered to match factory specifications for the listed Saab and Saturn vehicles. The 5-bolt mounting pattern with a 4.331-inch (110.0 mm) bolt circle diameter and a center hole diameter of 2.764 inches (70.2 mm) ensures proper fitment and secure installation.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors causing brake pulsation\u003c\/li\u003e\n\u003cli\u003eAddressing reduced braking efficiency due to rotor thickness below discard limits\u003c\/li\u003e\n\u003cli\u003eImproving heat dissipation to prevent brake fade during extended use\u003c\/li\u003e\n\u003cli\u003eEliminating noise and vibration from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eRestoring proper rotor dimensions for safe and reliable braking on Saab 9-3, 9-5, 900 and Saturn L-series models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of rust or debris before installation. Verify the rotor thickness is above the discard thickness specification of 0.906 inches (23.0 mm). Use the correct torque specifications for the 5 mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003ePerfect Stop Gray Armor-Plate, Premium rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
