034 Motorsport - 1-Piece Front Brake Rotor Upgrade Kit -  Audi B8 S4/S5/Q5 3.0T - 034-301-1025.

034Motorsport 1-Piece Brake Rotors are a direct replacement upgrade for Audi B8/B8.5 S4/S5/Q5 3.0T, offering improved cooling, durability, and braking consistency at a street-friendly price. Featuring directionally ventilated internal vanes, a high-strength CM-250 alloy, and a J-slot slotted friction face, these rotors are engineered to manage heat more effectively than factory straight-vane OEM rotors at far less cost to your wallet.

Designed for daily driving, spirited street use, autocross, and light track duty, they bolt directly to stock calipers and are compatible with factory or upgraded pads. Finished with a Geomet anti-corrosion coating and temperature indicating paint marks, these rotors deliver functional performance gains while being designed for years of real-world use.

Directional Cooling. Stronger Materials. Real Performance at a Fair Price:

034Motorsport 1-Piece Rotors deliver a meaningful braking upgrade for Audi and Volkswagen platforms without the cost of a two-piece system. Designed as a direct replacement for factory rotors, they combine advanced cooling technology, a high-strength alloy, and proven track-inspired features at a price point typically reserved for basic blank rotors.

Unlike factory rotors that rely on straight internal cooling vanes and soft iron alloys, 034Motorsport 1-Piece Rotors are engineered from the inside out to manage heat more effectively and hold up under repeated braking events.

Directionally Ventilated for Active Cooling:

Most OEM Audi and VW rotors utilize straight internal cooling vanes or no vanes at all, which create limited airflow and minimal active cooling effect. 034Motorsport rotors feature directionally ventilated internal vanes that pull air in from the center of the disc and force it outward. This increased airflow greatly improves heat transfer and cooling of the rotor, helping the rotor stay cooler during hard street driving, spirited back roads, autocross, and light track use. Cooler rotors maintain braking consistency and reduce the likelihood of fade, warping, or hotspots.

High Strength CM-250 Alloy:

Factory rotors are typically cast from relatively soft iron, which wears quickly and warps under high pressure and high heat. 034Motorsport 1-Piece Rotors use a Heat-Treated CM-250 special alloy formulated specifically for performance driving. This material is more resistant to heat cycling, less prone to warping, and better suited for repeated high-temperature braking than OEM rotors.

J-Slot Friction Face:

The J-slot slotted friction surface is designed to do more than just look aggressive. J-slots help clear debris from the pad surface, allow pad off-gassing under high temperatures, and distribute heat more evenly across the rotor face, reducing the likelihood of hot spots. This results in more consistent braking performance compared to traditional straight slots or drilled rotors, which can concentrate heat and increase the risk of cracking.

Street Friendly, Track Capable:

These rotors are optimized for daily driving, spirited canyon runs, autocross, and entry-level track days. They are fully compatible with stock calipers and can be used with factory pads or upgraded performance pads. For drivers engaging in more aggressive back-road use or extended track sessions, 034Motorsport 2-Piece rotors remain the ideal solution and are recommended for the highest thermal demands.

Built for Year-Round Use:

Each rotor is finished with a Geomet anti-corrosion coating to protect against rust and corrosion, making them suitable for all weather oncditions. Temperature-indicating paint marks on the rotor edge provide a visual reference for heat exposure during aggressive driving or track use.

Temperature-Indicating Paint Marks:

034Motorsport 1-Piece Performance Brake Rotors feature temperature-indicating paint marks on the rotor edge that provide a quick visual reference for heat exposure during aggressive street driving, autocross, or track use.

The paint changes color at specific temperature thresholds to help drivers understand operating conditions:

  • Green †’ White at 478°C (892°F)
  • Orange †’ Yellow at 571°C (1060°F)
  • Red †’ White at 640°C (1184°F)

If the red paint turns white throughout, the rotors are consistently operating beyond their intended temperature range. This may indicate the need for lower-friction brake pads, improved cooling, or upgrading to 034Motorsport 2-Piece Rotors, which have higher heat dissipation capabilities with their two-piece design.

Performance That Makes Sense:

034Motorsport 1-Piece Rotors are priced competitively with basic blank replacement rotors, while delivering meaningful performance improvements in cooling, durability, and braking consistency. This makes them one of the best value brake upgrades available for Audi and VW owners.

Good size, Durable, Easy to use
My dog doesn't really play with balls that much. But she does love a laser which I was hoping the light in this ball might mimic for her. And it does. She loves this ball. And the winter months when the days are short finding games we can play at the park is critical for her well-being. The ball came in an attractive packaging with a charger and charged quickly. It's a simple push of the button on the light to activate it. It will turn off on its own but light back up when it's moved, which is handy. The light has a soft glow to it which is pleasant to be around. The ball is easy to see at night and has a good bounce to it as well. My dog chewed on it for quite a bit and it's held up really well, so I will say it's pretty durable and chewable. The weight in the ball is nice and it's an easy throw. My only suggestion is to make sure that you have the light piece locked in place first. I have thrown it where the ball and the light went in two different directions. And that was my fault. Lol We have had some great fun with this ball at the park. For the short winter days it's a perfect addition to your pet's play routine. We love it.

Defective on arrival
Second ball defective. First ball received would not light. Second ball battery charged and locked. When unlocked to switch on light, the cylinder stuck in the ball and will not come out. I'm very disappointed. I've sent back and hope the third functions properly.

Our Dog Is OBSESSED – Night Play Game Changer!
This light-up dog ball is a total hit in our house. As you can see from the photos, the glow is bright and easy to spot even in complete darkness, which makes nighttime play so much safer and more fun. The motion-activated light turns on instantly when my dog nudges or bites it, and the 90-second auto glow is perfect. The silicone material feels soft but durable, gentle on teeth, and my dog loves carrying it around. USB-C charging is super convenient, and one charge easily lasts multiple evening play sessions. It’s also water-resistant, so no worries about grass or dew. Perfect size for small to medium dogs, and it keeps my pup engaged and active after sunset. Highly recommend for anyone who wants fun, visible, and stress-free night play with their dog!

Better yet imporbable than the original LaRoo Ball
I owned the LaRoo v1 (old version of this ball) my 100lb lab loved it. It was the first light up toy to resist the strength of this jaw. It glowed bright enough and stayed on long enough to be fun for the dog in the darkest settings. Unfortunately I was stress testing it and he was able to unscrew it at some point and destroy the ball. Supervised it was great. Onto this new one. It glows brighter for longer, great improvement on the original red one. My issue comes with the cap. They changed it from a threaded screw on cap to a bayonet mount (push in turn 1/16 of a turn its locked) the issue is that the bayonet plug was a few mm too short in tolerance and slipped out on our first play session. Its not nearly as secure as it once was. That being said a couple rounds of electrical tape around the perimeter of the plug and it now fits securely in the slot and is safe for puppy. This is a hard ball comparable to a baseball in size and softness. It doesn't make noise. The dog LOVES it. Its his favorite toy. If your dog plays fetch they will love this toy.

Not practical
I really wanted to like this ball, but it didn’t work well for us. The rubber is very hard and heavy, which made it difficult for my dog to catch it in the air and it was less enjoyable to play with overall. After only a short time, the plastic lid got stuck, and now I’m unable to open it to recharge the ball. The light feature is a nice idea, but between the hardness of the ball and the charging issue, it just wasn’t practical. Disappointing quality for the price.
