Girodisc Rear Iron Rotor Conversion – Mercedes E63 / CLS63 / SLS
The Girodisc A2-240 Rear Iron Rotor Conversion Kit converts your factory steel rear rotors to a high-performance two-piece floating iron rotor system for Mercedes E63, CLS63, and SLS models. It allows you to upgrade your brake system without replacing OEM hub components—delivering improved thermal management, reduced weight, and far better consistency under track or aggressive use.
Upgrade from Steel to Performance Iron
Mercedes E63, CLS63, and SLS vehicles often come with large, heavy steel rear rotors. The Girodisc A2-240 conversion lets you retain the stock hub assembly but convert to lightweight, high-quality cast-iron friction rings mounted on a 6061-T6 aluminum hat. This floating rotor system improves cooling, allows thermal expansion, and reduces unsprung and rotational mass while maintaining OEM caliper compatibility.
