GiroDisc 05-13 BMW 335i (E9X Incl xDrive) Slotted Front Rotors

These GiroDisc front rotors feature a unique slot pattern designed to help clear heat, dust, and gas away from the pad surface. This helps maintain consistent braking performance, especially during spirited driving or repeated hard stops. The rotors are made from a high-carbon, alloyed iron that's known for its strength and ability to handle thermal stress without cracking. This well-built material is crucial for a component that deals with significant heat buildup.

GiroDisc uses a proprietary slot design that's machined into the rotor face. Unlike some other slotted rotors, these slots are not sharp-edged, which helps to reduce pad wear and noise. The goal here is to get the benefits of slotting – improved cooling and gas evacuation – without the common drawbacks. The rotor hat is made from anodized aluminum, which is lightweight and corrosion-resistant, and it's attached to the rotor ring using high-strength fasteners. This two-piece construction allows for thermal expansion and contraction without stressing the rotor, which can help prevent warping over time.

This set is specifically for the front of your 2005-2013 BMW 335i, including xDrive models. When installing, it's always a good idea to refer to the manufacturer's instructions to ensure proper bedding-in procedures are followed. This helps the pads and rotors mate correctly for optimal performance and longevity.
