034 Motorsport - 1-Piece Front Brake Rotor Upgrade Kit - Audi B9 S4/S5/SQ5 - 034-301-1024.

034Motorsport 1-Piece Brake Rotors are a direct replacement upgrade for Audi B9/B9.5 S4/S5/SQ5, 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.

This will work but prep is key!
I have an older RV that the gelcoat has dulled and is oxidized, but otherwise in good shape. I have buffed and polished in the past only for it to last a short time. I was looking up different products to try and this one has such good reviews, I thought I would give it a try. I bought the kit with the Poliglow and the Poliprep, with the scrubber and the microfiber glove. I started with the poliprep and it did a great job of gettting the streaks and black marks off. You spend a lot of time scrubbing to your likeness because anything that is still on the gelcoat when you apply the poliglow, it will be locked in there. The Poliglow is like a clearcoat that goes over the gelcoat. You have to build up layers and here are some of the tips and tricks I figured out that really helped my finished RV look great. First, make sure the applicator stays damp, this keeps the poliglow more uniform across the glove. Also, stick it in a zip lock bag when not using, you do not want it to dry out while you are using it. I found out that applying this in direct sunlight in warm temps, is the best method. This allows the poliglow to dry really fast. The first 3 or 4 layers will look streaky and dull but this is ok and as you build up the layers, the shine will come back. I found if you do this when its cooler, the layers do not dry as quick and you will get some permanent streaking or running. I had to remove a section I did in the evening because I noticed this. When in direct sunlight, this gave me the best results with no streaking or running. It dries fast and you can keep working. Like it says, do not do big sections at a time, keep it to small what you can reach sections and build those up and move on. As far as how much to buy? I have a 40 ft toy hauler and I got to kits and I had just enough to finish the whole thing minus the nose cap. I have Durabak on the nose cap, so I dont need to worry about that. I ended up buying one more bottle of the poliglow to have for my maintenance coats. Overall, I am pleased with how my 10 year old RV looks and other than some of the decals show age, it looks new again. If I were to buy a new RV, I would put this on right away and preserve the whole RV including the decals. Its not too expensive and its a lot of work, especially the prep, but it does end up with great results.

Excellent shine
Excellent line of products. Looking at the picture, you can see what the camper looked like before the Poli Glow. To the left of the window is the after Poli Glow. It takes some elbow grease (follow instructions well) but well worth it.

One bottle covered my 20ft camping trailer 4 coats and with a little remaining for future touch ups. It definitely increases the gloss. I'm glad I didn't waste my time with wax. This is like an easy wipe on clear coat. I will report back in the future for longevity.

poli glow shine
its works great .when applying more coats the shinier it gets i used on several old boats because the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.
