Description
Description
The 034Motorsport 370x22mm 2-Piece Floating Rear Brake Rotor Upgrade for B9/B9.5 Audi A4/S4, A5/S5, Q5/SQ5, & RS4/RS5 is a complete replacement brake rotor and caliper carrier kit, designed to work flawlessly with the factory rear 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!
Weighing in at approximately 15.1lbs, each rotor reduces rotational weight by 1.6lbs on each corner over the factory 16.7lbs rotors, and increases rotor diameter from 330mm to 370mm! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture heat, while utilizing 36 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.
Upsizing the rear rotor size from 330mm to 370mm repositions the caliper further outward, increasing its leverage on the rotor. With this added leverage, the factory rear caliper can generate more braking force at the rear axle. This not only improves rear-end braking performance, but also helps take stress off the front brakes during hard stops. The result is a more balanced braking system with better stability, reduced front brake overload, and enhanced overall stopping confidence.
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 36 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 surface of contaminants and allows hot pad outgassing.
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.
