Featuring the innovative V3 snap-ring retention system, this two-piece rotor enables rapid, tool-free disc swaps. With precision slotting, dynamic balancing, and fade-resistant construction, it's the ideal upgrade for drivers demanding race-ready performance and minimal downtime.\u003c\/p\u003e\n\u003ch3\u003e\u003cspan class=\"accordion__toggle h6\"\u003e\u003cspan class=\"text-with-icon gap-4\"\u003eDescription\u003c\/span\u003e\u003cspan class=\"animated-plus group-expanded:rotate\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv class=\"accordion__content prose\"\u003e\n\u003cp\u003e\u003cspan\u003eThe Performance Friction 322.053.63 \u0026amp; 322.053.64 V3 Disc Rotor is a direct 2-piece rotor replacement for the BMW E46 M3 front brakes. They are designed to be used with the factory caliper, with no other parts or modifications necessary. Kit includes everything needed (rotor, hat and hardware) for a single rotor replacement. Priced per rotor. The V3 design features an all new retention ring that holds the hat and disc together without the need for traditional nuts \u0026amp; bolts. The simplified design also helps save weight and makes rotor replacement a breeze. The 2-turn retaining ring is held in a groove in the hat that overlaps the rotor flanges, effectively locking the rotor to the hat.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eV3 style mounting hardware\u003c\/li\u003e\n\u003cli\u003eHigh Carbon Alloy with copper and molybdenum for high temperature strength and durability.\u003c\/li\u003e\n\u003cli\u003eVanes turned OD and ID for balance to reduce thermal warping and vibration.\u003c\/li\u003e\n\u003cli\u003eRunout less than .001 inches, reducing Pulsation and Vibration.\u003c\/li\u003e\n\u003cli\u003eThickness variation less than .0003 inches reduces Pulsation and Vibration.\u003c\/li\u003e\n\u003cli\u003e47 or more vanes for superior thermal capacity.\u003c\/li\u003e\n\u003cli\u003eAircraft quality heat treated for micro structure alignment and durability.\u003c\/li\u003e\n\u003cli\u003eSurface finish less than .7 microns.\u003c\/li\u003e\n\u003cli\u003e100% measured and inspected to meet tolerance specifications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e2-piece rotors offer better cooling over a one-piece design. Performance Friction's full floating Direct Drive attachment system allows the brake disc to naturally expand\/contract both radially and axially without being constrained by the hub. This helps eliminate rotor warping, vibrations and pulsations. Due to the high quality of Performance Friction's design and manufacturing, the Direct Drive rotors are completely silent and rattle-free - a trait not typically found in many competitor's 2-piece designs. The hat assembly is completely reusable - no need to buy the entire rotor again! And, because the rotor is designed for use with the factory caliper, you can still use your favorite Performance Friction brake pads!\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eNote:\u003c\/span\u003e\u003cspan\u003ePerformance Friction Brake Pads are recommended for this set up. All other pads must be checked for proper rotor clearance at installation and periodically as they wear. Some brands of brake pads will fit at time of installation, but may contact the rotor-hat during use which can lead to brake failure.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003cspan class=\"accordion__toggle h6\"\u003e\u003cspan class=\"text-with-icon gap-4\"\u003eTechnical Details\u003c\/span\u003e\u003cspan class=\"animated-plus group-expanded:rotate\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv class=\"accordion__content prose\"\u003e\n\u003cp\u003eCommon Vehicle Fitments:\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003cdiv class=\"table-scroller\"\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr data-cow-cart-observed=\"true\"\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eE46 M3\u003c\/td\u003e\n\u003ctd\u003e2000-07\u003c\/td\u003e\n\u003ctd\u003eFront\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/figure\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: 322.053.63 — Left-side fitment for BMW E46 M3 front\u003c\/li\u003e\n\u003cli\u003e2-Piece Floating Design — Superior heat dissipation and durability\u003c\/li\u003e\n\u003cli\u003eSlotted Rotor Face — Improves cooling and pad deglazing for consistent performance\u003c\/li\u003e\n\u003cli\u003eV3 Snap-Ring Retention System — Fast, tool-free rotor changes with a spiral lock ring\u003c\/li\u003e\n\u003cli\u003eDynamically Balanced \u0026amp; Precision Machined — Minimizes vibration and improves pedal feedback\u003c\/li\u003e\n\u003cli\u003eReusable Hat Assembly — Long-term cost efficiency with repeatable rotor swaps\u003c\/li\u003e\n\u003cli\u003eFade-Resistant Build — Engineered for endurance racing, track days, and high-performance street use\u003c\/li\u003e\n\u003cli\u003eLightweight Construction — Reduces unsprung mass for sharper handling response\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"OGR Dealer","offers":[{"title":"Default Title","offer_id":53728819118261,"sku":"PF32205363","price":599.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/4844\/4597\/files\/v3-slotted-web_1_601b0907-408e-4e9d-8212-7a39e03acbcb.jpg?v=1794244931","url":"https:\/\/naroescapemotorsports.com\/products\/pfc-v3-slotted-rotor-hat-assembly-left-bmw-e46-m3","provider":"Naroescape Motorsports","version":"1.0","type":"link"}
