Description

The 034Motorsport 360mmx34mm 2-Piece Floating Front Brake Rotor Upgrade Kit for the 10 Audi S5 is a complete replacement brake rotor, designed to work flawlessly with the factory front calipers. Upgrading your front rotors will increase overall braking performance in street, track, and HDPE driving conditions, as they keep your brakes cool and strong all day long!

Weighing in at approximately 26.8lbs, each rotor reduces rotational weight by 3.85lbs per corner over the factory 30.65lb rotors! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture heat, while utilizing 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

The central hat portion of the 034Motorsport rotor is made of 6061-T6 aircraft specification aluminum. The disc is constructed out of a proprietary metal alloy that can withstand immense braking temperatures while holding form.

The face of the rotor utilizes J-Slot slots to clean the pad and surface of contaminants and allows hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor.

The rotor and hat have a floating mount system that utilizes high-strength alloy steel bobbins. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat.

Directionally Ventilated for Active Cooling:

Most OEM Audi and VW rotors utilize straight internal cooling vanes, which allow for limited airflow and minimal active cooling effect. 034Motorsport rotors feature directionally ventilated internal vanes that pull air in from the center of the disc and force it outward. This increased airflow greatly improves heat transfer and cooling of the rotor, helping the rotor stay cooler during hard street driving, spirited back roads, autocross, and light track use. Cooler rotors maintain braking consistency and reduce the likelihood of fade, warping, or hotspots.

2-Piece Rotors

High Strength CM-250 Alloy:

Factory rotors are typically cast from relatively soft iron, which wears quickly and warps under high pressure and high heat. 034Motorsport 2-Piece Rotors use a Heat-Treated CM-250 special alloy formulated specifically for performance driving. This material is more resistant to heat cycling, less prone to warping, and better suited for repeated high-temperature braking than OEM rotors.

J-Slot Friction Face:

The J-slot slotted friction surface is designed to do more than just look aggressive. J-slots help clear debris from the pad surface, allow pad off-gassing under high temperatures, and distribute heat more evenly across the rotor face, reducing the likelihood of hot spots. This results in more consistent braking performance compared to traditional straight slots or drilled rotors, which can concentrate heat and increase the risk of cracking.

2-Piece Rotors

Temperature-Indicating Paint Marks:

034Motorsport 2-Piece Performance Brake Rotors feature temperature-indicating paint marks on the rotor edge that provide a quick visual reference for heat exposure during aggressive street driving, autocross, or track use.

The paint changes color at specific temperature thresholds to help drivers understand operating conditions:

  • Green → White at 478°C (892°F)
  • Orange → Yellow at 571°C (1060°F)
  • Red → White at 640°C (1184°F)

If the red paint turns white throughout, the rotors are consistently operating beyond their intended temperature range. This may indicate the need for lower-friction brake pads or improved cooling
