DIXCEL FS Replacement Rotor Rings - Brembo 09.7792.12/22 - 380x34mm 12 Slot

Restore your braking performance with Dixcel FS replacement rotor rings, engineered in Japan and developed through decades of OEM supply and motorsport experience. The FS series is built for sustained competition use, where consistent friction, heat management, and dimensional stability under repeated high-energy stops matter more than anything else.

These are replacement friction rings only. They are designed to be fitted to your existing Brembo two-piece assembly, reusing your current hat, bobbins, and hardware. This allows a worn disc face to be refreshed without replacing the complete assembly.

This listing covers the Brembo 380 x 34mm two-piece assembly, cross-referenced to Brembo part numbers 09.7792.12 and 09.7792.22 and 90.6536 and 90.6537. The rings are side-specific: FS-38034B48R is the right hand ring and FS-38034B49L is the left hand ring. Both are supplied together as a pair. The SLIT-12 face carries twelve slots for consistent bite and clean pad degassing.

Important: This is a motorsport component intended for competition use. Bolts, nuts, bobbins, and springs are not supplied and must be reused from your existing assembly or sourced separately. Please confirm your hat, hardware, and disc dimensions before ordering.
