Girodisc D2-044 Replacement Ring FAQs
Are these compatible with OEM Mercedes brake hats? No. These rings are designed exclusively for Girodisc aluminum hats and will not fit OEM assemblies.
Do these include new hardware? Yes. Every set includes new drive pins, bolts, and washers for proper installation and long-term reliability.
Can these be used with performance brake pads? Absolutely. Girodisc rings perform best when paired with high-performance street or track compounds such as Pagid, Ferodo, or Endless.
How do these improve braking over stock rotors? The two-piece design reduces unsprung mass and improves heat transfer, giving you better pedal modulation and quicker cooling after repeated hard stops.
