The 380 mm rotor uses a 38 mm thickness, 85 mm hub bore, and 130 mm bolt circle with a 6\/5 hole arrangement. Its floating, two-piece design helps the disc expand more evenly during hard use, while the coated finish and high-carbon construction support durability in performance-oriented Porsche Cayenne brake applications. This part number, 460.1557.75, is also cross-referenced to 955 351 401 60 and BD-3342 for the same application.\u003c\/p\u003e\u003cp\u003eFormula Z is Zimmermann’s performance rotor line, developed for vehicles with increased braking demands from tuning or upgraded chassis setups. The line combines a floating mounting concept with corrosion-resistant coating and certification notes supplied with the rotor, making it a practical OE-style alternative where stronger thermal handling is required. If you are replacing a worn Porsche Cayenne front left brake rotor, 460.1557.75 matches the listed fitment and performance-focused design.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Rotor Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake vibration caused by uneven rotor wear.\u003c\/li\u003e\n\u003cli\u003eHeat-related cracking from repeated heavy braking.\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency under high load.\u003c\/li\u003e\n\u003cli\u003eCorrosion on exposed rotor surfaces.\u003c\/li\u003e\n\u003cli\u003eRotor wear on Porsche Cayenne front left applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify PR code and fitment before installation. This rotor is listed for Porsche Cayenne front left applications only, with separate fitment notes for 2004-2006 and 2008-2010 model years. Confirm rotor dimensions, hub bore, bolt circle, and minimum thickness against the vehicle specification before service. Part number 460.1557.75 should be matched to the correct axle position and PR number during brake repair.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eZimmermann supplies this rotor with general ABE certification or an ECE note, depending on market requirements.
