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)

The best pillow I've ever had!
Size: King (U.S. Standard), Number of Items: 2
I have tried a LOT of pillows over the years. I'm allergic to feathers so I need something non-allergenic. I am a back and side sleeper, and all of the pillows I've tried have gone flat after just a few weeks. Well I've had these for a couple of months now, and they show no sign of flatness whatsoever. A few punches or a fluff cycle in my dryer each week plumps them right up. They are just the right kind of firmness -- enough give so that I'm not kinking my neck, but not too much give so that my head ends up on the mattress by morning. I just cannot say enough good things about these pillows. I'm so excited that I finally found one that is perfect for me. As others have said, they arrive vacuum packed. They look a bit weird, and it will make you wonder how they will ever fluff up from how flat they are when they arrive. But look at it as an opportunity to take out your frustrations lol. Whack them on a wall, punch the bejeebers out of them, it will make you feel good and it will inflate them right up. Or throw them in the dryer like I did and in 15 minutes you will have a perfectly fluffy pillow. All in all, I highly recommend these. The price point is so reasonable, and they seem to be well made. Five stars all around.

Updated: actually very good pillows for the price
Size: King (U.S. Standard), Number of Items: 2
Wow! It is amazing at how compact these arrive in their package... it actually was a bit of work to get them out of the packaging it was so tight. Once out, they immediately began to "size up" and within about 15 minutes had reached maximum size. They are comfortable pillows, but lack the firmness that I wanted. On a scale of 1-5, I'd rate them 3 at the most, possible a 2 if 5 is maximum firmness. Updated: After about a month or so of having these, I have to admit my initial impressions were flat out wrong... these are fantastic... comfortable and more firm than I initially thought... probably 4-4.5 out of 5 on the firmness scale now. Maybe they just take a while to decompress? Anyway, would now definitely recommend!

Great pillows
Size: King (U.S. Standard), Number of Items: 4
These pillows are a must buy. Very soft and sturdy. It feels like a cloud when I lay on them. And I love how long they are too. The price for the amount was a huge bonus too.

I only use these pillows now
Size: King (U.S. Standard), Number of Items: 2
We’ll see if they keep their shape so far they have. They cradle my head well and I don’t wake up with neck pain anymore like I used to with my other pillows. Even my JC Penny feather down pillows lost shape so I switched to these and they are perfect. Extra large is great for me as I tend to roll around when I sleep. Perfect for back and side sleepers like me.
