GiroDisc 05-13 BMW 335i (E9X Incl xDrive) Slotted Rear Rings

These GiroDisc rear rotor rings are made from a high-carbon iron alloy, a material chosen for its ability to handle heat without warping. The rings are designed to be a direct replacement for your factory rear rotors on 2005 through 2013 BMW 335i models, including those with xDrive. This means you can upgrade your braking performance without needing to change your entire caliper setup or mounting hardware.

What sets these apart is the slotted design. The slots on the braking surface help to sweep away dust and gas that can build up between the pad and rotor during hard braking. This keeps the pad surface cleaner and allows for more consistent contact, which translates to more reliable stopping power when you need it most. The high-carbon iron construction also offers improved thermal capacity over standard rotors, helping to reduce the risk of brake fade during spirited driving or track use. Because these are replacement rings, you'll reuse your existing aluminum hats, saving on cost and simplifying the installation process. Just be sure to properly clean the hats and torque the new rings down according to manufacturer specifications.

When you're ready to replace your rear rotors, these GiroDisc rings offer a solid upgrade. They're a popular choice for drivers looking for improved braking performance and durability over stock components. Make sure you have the necessary tools to remove and install the rotor rings, and always refer to the manufacturer's installation guide for the correct procedure.
