034Motorsport 2-Piece Floating Brake Rotor Upgrades for BMW G20 M340i and Toyota A90/91 GR Supra are a complete replacement brake rotor, designed to work flawlessly with the factory calipers. Upgrading your rotors will increase overall braking performance in street, track, and HDPE driving conditions, as they keep your brakes cool and strong all day long!

With our lightweight design, the rotors retain proper thermal mass in the rings to adequately capture, and 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 rotor utilizes 48 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

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.
