NVH Levels: None - Low


NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. The 034Motorsport 2-Piece Brake Rotors transfer none to low amounts of noise to the cabin based on user feedback. This NVH is relative to the brake pad installed with the brake rotor. Different brake pads will have different resonances when passing over a rotor with slots, which can sometimes make a slight whirring noise. The sounds from these rotors are the direct result of the performance improvements they make to the braking. The J-slots release gas from under the brake pad, and the high-density directional aero veining in the rotors move substantial air, all resulting in more sounds of air moving. The installation of other suspension components can also affect the NVH transferred. NVH is subjective, so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please email [email protected] for further assistance.
   

Product Description:

The 034Motorsport 380mmx28mm 2-Piece Floating Rear Brake Rotor Upgrade Kit for the BMW F8X BMW M2 C/CS, M3/M4 C/CS, & M4 GTS is a complete replacement brake rotor kit, designed to work flawlessly with the factory rear calipers found on the BMW F8x M2 Competition/M3/M4.

Weighing in at approximately 22.2 lbs, our lightweight design retains proper thermal mass in the rings to adequately capture heat, while utilizing 72 directionally curved vanes to forcefully flow cool air through the rotor to 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 allowing hard street use and long days at the track, allowing you to drive versus working on the car. These rotors improve thermal capacity by utilizing 72 directionally curved cooling vanes to forcefully flow cool air through the rotor and are profiled specifically to improve heat dissipation compared to the OE rotor vane design.

The face of the rotor utilizes J-Slot slots which increase braking surface area over drilled rotors as well as clean the pad and surface of contaminants and allow hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor. This J-Slot design also improves upon the OEM drilled rotors, as drilled rotors are prone to cracking after repeated abuse.

With its true 2-Piece design, the rotor and hat have a floating mount system that utilizes high-strength alloy steel bobbins. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat. This 2-Piece design also makes repair costs in the future significantly less overtime, as only the rotor rings would need to be replaced.

Note: For F8X M2 CS, M3/M4 Competition/CS, or M4 GTS owners with the factory M-CCB Carbon Ceramic Brake Package (2NK) looking for a much more cost-effective brake rotor alternative, the 034Motorsport 2-Piece Floating Rotors are a direct swap for your factory carbon ceramic brake rotors!

The brake calipers and dimensions of the carbon ceramic brake rotors are identical to the calipers and iron brake rotors in the 2NH Brake Package found in the M2 Competition and M2 CS, making them cross-compatible.

034Motorsport 2-Piece Rotors have been thoroughly tested in high-intensity motorsport events, proven to significantly improve braking and thermal headroom and for extreme performance street and track driving, making them the perfect replacement rotor for your BMW F8X.

Features:

  • Lightweight Construction (22.2lb 034Motorsport Rotor), the Same Weight as OEM, but with Improved Metallurgy and Thermal Capacity, despite Lightweight Construction to Match OEM Rotor Lightweight Design Elements
  • Floating, 2-Piece Design
  • Aerospace Grade Aluminum Hats

Amazing value for the price - perfect for my 2 year old book lover!
Format: Hardcover
This is an amazing value! My 2yo loves books and princesses, and I am trying to work on her independence (and find screen free activities). She was able to figure out the reader on her own, and can easily follow along. Of course, she would rather I do it with her but we're working on it. The pages are very thin paper, but that's ok considering the price for 8 books. Just might want to keep an eye on little hands. The art work doesn't look cheap, and despite the delicate pages the books are good quality. The reader is cool, sound quality is meh but again, under $20. I wish the box didn't have display holes so it would be a better storage case, but even the cardboard is pretty good so I can make it work. I will definitely be gifting this and buying more for my girl because you cannot beat the value of this!

Great Read-a-Long
Format: Hardcover, Format: Hardcover
This is a great idea for young children to listen and learn to read. It's easy for little ones to learn how to use it. Just match the picture on the selected book to the corresponding picture on the electronic reader and that's it. The electronic reader voice speaks clearly and understandable. The words are printed on the page, making it easy to follow along. This was the perfect book for my five-year-old princess granddaughter.

Great for 4 Year Old, Pages Need to Be Thicker
Format: Hardcover
I got these for my daughter for Christmas last year and she loves them. The reader is easy to operate - press the princess and then press the buttons that correspond to the page and it reads it to you. I like the variety of princesses included, such as Mulan, since she's not often featured. There was Merida and Tiana as well as the most popular ones like Ariel, Belle, Jasmine, Snow White, etc. The books are hardcover, which is nice, but the pages are so thin and will bend and tear over time. The pages are colorful and the stories are fun to listen to. These remind me of the books on tape of my youth. Very happy with the purchase.

Great Product!
Format: Hardcover
We bought this for a 14 hour car ride! It was a life saver kept our 4 year old and 6 year old nieces occupied. They love the stories and the illustrations in the book were beautiful. The voice of the narrator is so much fun. We would recommend for sure. The price was really great as well.
