PRODUCT DESCRIPTION:

The 034Motorsport 345mmx30mm 2-Piece Floating Front Brake Rotor Upgrade Kit for the Audi B8/B8.5 S4/S5 is a complete replacement brake rotor kit, designed to work flawlessly with the factory front calipers found on the B8/B8.5 S4/S5.

Weighing in at approximately 19.00lbs, each rotor reduces rotational weight by 5.10lbs per corner over the factory 24.10lb rotors! While reducing weight, the rotor retains 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. From the factory, the same straight-veined rotor is used on both sides of the S4. The 034Motorsport rotors utilize 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat and are unique to the left and right axle to provide a substantial increase in cooling efficiency over the factory rotor design.

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 events while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat.

  • Lightweight Construction (19.00lb 034Motorsport Rotor vs 24.10lb OE Rotor)

**Please Note: Type III hard anodizing of aluminum is considered as a functional surface coating process. While we always aim for color consistency, color variations may exist from batch to batch due to the nature and variables in the anodizing process.

As Advertised!
Product arrived promptly & well-packaged (shrink wrapped packaged & enclosed inside additional box). Golf vest was received "as advertised" & appears to be of good quality. Vest was fairly priced & is very comfy, lightweight, stylish & wrinkle resistant. Purchased as a gift for my adult son for his future golf adventures. Size/fit will need to be determined by my son when he prepares for his next golf outing. Very pleased with my purchase & will consider additional purchases from seller in the future.
