Dixcel FS Replacement Rotor Rings (Pair) - 355x32mm 12-Slot - AP CP4542-106/107 / CP4542-306/307 / Alcon DIV2146 / DBA 52750.1
Refresh your two-piece big brake kit with Dixcel FS replacement rotor rings, engineered in Japan and developed through decades of OEM supply and motorsport experience. Dixcel rotor rings are designed to deliver consistent braking performance, stable pedal feel, and reliable control under demanding circuit and trackday conditions, while preserving the aluminium centre hats, mounting bobbins, and hardware from your existing two-piece BBK setup.
This listing covers a matched left and right pair of 355x32mm 12-slot Dixcel FS replacement friction rings (part number FS-35532A22R/23L). 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.

Important Fitment Notes
- This product is a replacement rotor ring only - aluminium hats, mounting bobbins, and hardware are NOT included. You must reuse the centre hat and hardware from your existing two-piece BBK or pair these rings with a compatible new hat.
- Confirm your current rotor's outer diameter, thickness, mounting PCD, and bolt hole pattern match the specifications above before ordering.
- Two-piece replacement rings allow significant cost savings compared to replacing an entire two-piece rotor assembly when only the friction ring is consumed.
- Cross-reference part numbers and specifications with your BBK manufacturer's documentation if your specific kit is not listed above.
BBK manufacturer cross-references, dimensions, and fitment notes are provided in the tabs above. Please ensure your existing rotor specifications, BBK kit details, and hardware compatibility are confirmed before ordering.
