This product line focuses on providing solid rotors with smooth surfaces that ensure consistent braking performance and durability. The 121.34025 rotor is part of this line, delivering dependable stopping power for BMW vehicles requiring a direct replacement rotor without ABS tone ring features.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis Centric disc brake rotor is a solid type rotor, meaning it does not have venting channels, which suits applications where heat dissipation demands are moderate. The smooth surface type ensures even pad contact and wear. With a nominal thickness of 0.394 inches (10.000 mm) and a discard thickness of 0.331 inches (8.400 mm), this rotor provides a clear service life indicator for replacement. The overall height of 2.406 inches (61.100 mm) and outside diameter of 11.811 inches (300.000 mm) match OEM dimensions for proper fitment on compatible BMW models. The rotor features five lug holes with a 4.724 inch (120.000 mm) bolt circle diameter and a center hole diameter of 2.953 inches (75.000 mm), ensuring secure mounting. This rotor does not include an ABS tone ring or bearings, so it is intended for vehicles without ABS sensor integration on the rotor itself.\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 rotor thickness below discard limits to restore braking efficiency\u003c\/li\u003e\n\u003cli\u003eResolving uneven brake pad wear due to rotor surface imperfections\u003c\/li\u003e\n\u003cli\u003eEliminating noise or vibration related to damaged or out-of-spec rotors\u003c\/li\u003e\n\u003cli\u003eMaintaining proper brake system performance on BMW 525i, 525iT, 530i, and 535i models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify rotor thickness before installation to ensure it meets minimum discard thickness\u003c\/li\u003e\n\u003cli\u003eClean rotor surface and hub mounting area to prevent uneven rotor seating\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with vehicle ABS system as this rotor does not include an ABS tone ring\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and replace if worn to ensure optimal rotor performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric manufactures the C-TEK Standard Disc Brake Rotors to meet or exceed OEM standards for fit and function.
