GiroDisc 12-16 Mercedes-Benz SLK55 (R172) Slotted Rear Rings

Maintain top-tier braking performance in your AMG with Girodisc rear replacement rings for the Mercedes A45, CLA45, and GLA45. These precision-engineered high-carbon iron rings are direct replacements for your existing Girodisc two-piece rotor assemblies, restoring factory fit and race-level stopping confidence. Each Girodisc ring is crafted from proprietary high-carbon cast iron for exceptional durability, heat control, and resistance to cracking under heavy braking. The directional curved vane design acts as an internal pump to pull air through the disc, reducing brake fade and maintaining consistent pedal feel. Machined and finished entirely in the USA, Girodisc replacement rings ensure long service life and repeatable braking performance for high-output AMG models.
