These rings are designed as direct cross-references for popular two-piece big brake kits from AP Racing, Alcon, and DBA, with matching dimensions, mounting PCD, and bolt pattern. The 12-slot pattern delivers improved bite, gas evacuation, and pad cleaning compared to plain rotors, while the ring-only design significantly reduces both replacement cost and rotational mass compared to full two-piece rotor assemblies.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Big Brake Kit Applications\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAP Racing\u003c\/strong\u003e CP4542-106 \/ CP4542-107 \/ CP4542-106\/107 (paired set)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAP Racing\u003c\/strong\u003e CP4542-306 \/ CP4542-307 \/ CP4542-306\/307 (paired set)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlcon\u003c\/strong\u003e DIV2146X717 \/ DIV2146X717C24L \/ DIV2146X717C24R (paired set)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDBA\u003c\/strong\u003e 52750.1 (5000 Series two-piece replacement ring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOther manufacturers'\u003c\/strong\u003e two-piece BBKs sharing 355mm OD, 32mm thickness, 244mm ID, 215.9mm mounting PCD, and 12 x 6.4mm bolt holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eRotor Ring Specifications\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003eDixcel Part Number: FS-35532A22R\/23L (paired set)\u003c\/li\u003e\n  \u003cli\u003eDixcel Reference: AP 355 x 32 \/ CP4542-106\/107\u003c\/li\u003e\n  \u003cli\u003eSlot Pattern: SLIT-12 (12 directional slots)\u003c\/li\u003e\n  \u003cli\u003eOuter Diameter: 355.0mm\u003c\/li\u003e\n  \u003cli\u003eThickness: 32.0mm\u003c\/li\u003e\n  \u003cli\u003eInner Diameter: 244.0mm\u003c\/li\u003e\n  \u003cli\u003eHat Bore: 195.0mm\u003c\/li\u003e\n  \u003cli\u003eMounting PCD: 215.9mm\u003c\/li\u003e\n  \u003cli\u003eMounting Holes: 12 x 6.4mm\u003c\/li\u003e\n  \u003cli\u003eMounting Hardware: M8 (8.0 x 8.0mm)\u003c\/li\u003e\n  \u003cli\u003eHeat Capacity: 39,000 \/ 78,000 (per ring \/ paired)\u003c\/li\u003e\n  \u003cli\u003eSold As: Pair (Left and Right)\u003c\/li\u003e\n  \u003cli\u003eOrigin: Made in Japan\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eImportant Fitment Notes\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThis product is a replacement rotor ring only\u003c\/strong\u003e - aluminium hats, mounting bobbins, and hardware are NOT included.
