034 Motorsport - Audi B8 S4/S5 2-Piece Floating Front Brake Rotor Upgrade Kit.

The 034 Motorsport 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 aluminium. 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)

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.
