IMPORTANT! When purchasing, please provide additional information in the order notes, such as: car model, car type (Street, Sport, Racing) and caliper color (purple, yellow, black, green, red). After placing your order, our staff will check availability and confirm the shipping price.

D2 Racing Big Brake Kits offer unrivaled stopping power. The clamps are available in purple, black, yellow and red.

Hollow sports clamps are made of aluminum using a monoblock forging process to achieve an even grain structure. Then CNC 3D technology was used.

The calipers are characterized by reduced weight and very good heat dissipation, which effectively reduces brake temperature and increases braking power.

The clamps have a hot-pressed carbon manufacturer's logo.

Set contains:

  • 2 x ventilated discs with slots or holes, with aluminum bells (compatible with all OEM separate handbrake systems, drum, electric, etc.)
  • 2 x forged aluminum monobloc brake calipers.
  • 2 x braided brake lines.
  • All required mounting hardware (brackets, screws, instructions, etc.).

1 x set of brake pads for your choice:

  • Street (Resistant to temperatures up to 600 degrees)
  • Sports (Resistant to temperatures above 600 degrees)
  • Racing (Resistant to temperatures up to 1000 degrees)

Please remember that the clamps will be larger than standard ones and refer to the table below before choosing the clamps:

Minimum wheel size (inches) Disc Size(mm)
15 286
16 304
17 330
18 356
19 380
20 400

Differences between slotted and drilled brake discs:

Notched:

In slotted brake discs, small recesses (four to eight evenly distributed) are typical, milled on the surface of the brake disc.

Grooves provide the same cooling benefits as holes, but with less risk of separation and gapping because the grooves do not typically extend over the entire surface of the rotor (although there are some designs on the market today).

The grooves are usually oriented and curved so that they can cover the entire surface of the brake pads, providing much better ventilation than a series of holes. The condition of the brake disc can be assessed based on certain types of cuts.

The grooves also create a "shave" effect that keeps the surface of the brake pads cleaner for better steam contact.
In addition, the presence of cuts works like a grater, increasing the car's braking efficiency.

At the same time, you should be aware that the wear of the pads increases. In order to avoid rapid abrasion, it is recommended to select high-quality pads for such discs.

Drilled:

Drilling 30 to 40 evenly spaced holes in the brake discs improves air ventilation and cooling effect.

The holes actually had an unexpected benefit. They created channels for the extraction of hot gases emitted by the brake pads. Phenolic resins, which are used as a binder to connect brake pads, emit steam when heated excessively. The gas can form a boundary layer between the pads and the brake disc, which reduces friction.

In our case, the boundary layer of gas between the surface of the pads and the brake disc prevents the pads from connecting with the brake disc, reduces friction and braking force, just at the moment when the driver needs it the most.

If the brake disc is perforated or has slots, holes or grooves that separate the boundary layer and allow gas to escape, then the pads can make full contact with the brake discs. In addition, holes and grooves help remove dust and dirt that gets into the space between the brake disc and pads.

At a microscopic level, dirt between the pads and the brake disc can reduce the couple's contact area. Naturally, this also reduces friction and equipment efficiency. Therefore, the holes, while helping to remove dust and dirt, provide the pads with the ability to maintain maximum surface contact.

Other information:

  • D2 Racing calipers are machined from aircraft-grade aluminum, and the pistons mounted in them have very high temperature resistance (tested up to 1,000 degrees Celsius).
  • D2 Racing managed to keep the caliper's weight low while providing significant improvements in braking power.
  • There is a carbon D2 logo on each clamp.
  • 5-year warranty against leaks and 10 years against cracks and deformation
  • TUV and ISO9001

Out of date and just plain not good instruction
Format: Kindle
This has problems that I have seen from many non-educators when they write an instructional book (so I hope she is not an actual educator). The book makes leaps of faith of knowledge and has a belief that they have shown you well enough to do one thing (which it doesn't) and that you can extrapulate from that knowledge to do something completely different. They makes these leaps of faith in the first couple hours, when people are just getting used to coding in this language. This book also fails to even tell you what different parts of the code are doing, so that you can make those leaps of knowledge. I also find this happens a lot when people write coding books. They know how to code, so they figure if they just show you parts of a code you will figure out why it did what it did, instead of explaining to you what different parts of code actually do when you put them together. I made it almost through hour two before I gave up trying to decipher all the nonsense that was written in this book. In hour two they have you make a sphere, but never actually show you how to make the sphere, but then start telling you how to create dialog for the sphere. Apparently in hour 1, even though it was never explained, I was supposed to understand how to make a lava field with objects.

Must-read book for everyone (not just Ai proponents)
Format: Paperback
I realize I say this about every AI book I read, but this one really is the best (so far), and most important in my view."Atlas of AI" by Kate Crawford is a well-researched work that should appeal to AI enthusiasts and opponents alike; not because it flatters either side, but because it challenges both to think beyond the usual narratives. Whether you see Ai as a revolutionary tool for progress or a dystopian force of unchecked power, there’s no denying that it it is shaped by real-world systems of labor, industry, and politics.This book makes it clear: Ai is not just about algorithms and efficiency. It is about power: who wields it, who profits from it, and who is left to bear its costs. For those who celebrate Ai’s potential (like me), Atlas of AI offers a sobering look at the material and ethical realities behind the inertia and hype.For those who critique AI as a damaging or dystopian force, the book provides a well-researched (eye-opening) foundation for those concerns.What makes it especially compelling is that it doesn’t fall into the trap of alarmism OR blind optimism. Instead, Crawford takes us on a deep, methodical journey through the infrastructures that sustain artificial intelligence, revealing the hidden costs (labor, environmental, political) that come with EVERY so-called innovation.**Deconstructing the Myths of AI**One of the book’s greatest strengths is its ability to cut through the persistent myths surrounding artificial intelligence. Crawford systematically dismantles the notion that AI is a purely immaterial, frictionless technology. She examines the vast mining operations necessary to produce hardware, the exploitative labor practices behind data annotation, and the enormous energy demands of AI training model. Ai, in her analysis, is not an autonomous or inevitable force—it is an industrial system deeply intertwined with capitalism, surveillance, and environmental degradation (much of her research applies to Big Tech, and not just Ai). This perspective is crucial in an era where Ai is often presented as a revolutionary technology that exists outside of history and politics.Crawford makes it clear that Ai is not “just math” but a political tool wielded by those in power, often reinforcing existing inequalities. The Ethics of Extraction and Control: One of Crawford's most compelling arguments is the framing of AI as an extractive industry: one that harvests resources, labor, and data in much the same way as colonial enterprises have in the past.The book traces how Ai development is dependent on resource-intensive practices, from lithium mining for hardware to the invisible armies of low-wage workers tasked with cleaning and labeling data. Crawford argues Ai is a system built on the extraction of value from the most vulnerable populations, whether they be gig workers, Amazon's "Mechanical Turk" laborers, or the communities living in the shadow of server farms that consume enormous amounts of water and energy.Crawfors cites numerous examples of how corporations like Google and Amazon, and even the government, skirt the system to save on taxes, while promising better futures to the resource-rich communities they exploit. The theme of extraction extends beyond the physical to the digital realm.Crawford shows how personal data is commodified under the guise of “training AI,” reinforcing the asymmetrical relationship between those who generate data and those who profit from it.The book’s critique aligns with broader concerns about surveillance capitalism, demonstrating how Ai is often wielded as a means of control rather than liberation. (I learned some sad truths about local community policing and Ai) AI and the Politics of Classification Crawford explores how classification systems, often presented as objective/neutral, are deeply embedded with biases. Ai systems are trained on datasets shaped by human prejudices, yet are frequently deployed as infallible arbiters of truth. Crawford examines how facial recognition, predictive policing, and automated hiring systems encode and reinforce racial, gendered, and socioeconomic biases, often amplifying systemic discrimination. This analysis is particularly relevant in today’s discussions on AI ethics. Crawford’s work underscores that Ai bias is not simply a technical glitch to be fixed, but rather a feature of the broader political and economic structures that Ai is designed to serve. A Necessary and Timely Intervention For those who have followed debates on Ai ethics, surveillance capitalism, and data justice, Atlas of AI provides a well-researched and compelling synthesis of these concerns, free from the noise we commonly hear on social media outlets. It is particularly valuable in challenging the mainstream, corporate-driven narratives that portray Ai as an inevitable and benign technological force. Crawford’s writing is insightful, well-documented, and accessible, making complex ideas understandable without sacrificing depth. While the book is critical in tone, it does not merely scold Ai developers; rather, it offers a crucial intervention in ongoing discussions about how Ai is developed, deployed, and governed.The book had a surprisingly anti-capitalist/anti-technocratic tone, that inspired me to continue learning/aligning under the anti-fascist flag so many of us wield. For artists, researchers, and technologists (especially those working at the intersection of Ai and creative expression) Atlas of Ai serves as a stark and vital reminder that technology is never neutral. It invites us to think critically about the systems we engage with and the ethical implications of our participation in Ai-driven ecosystems (and really, all major technologies). Atlas of AI is an essential read for anyone interested in understanding the broader implications of artificial intelligence beyond the hype. It moves beyond discussions of algorithms and model accuracy to examine the power structures that shape Ai’s impact on society. By reframing AI as a material and political phenomenon rather than a disembodied technological marvel, Crawford provides a necessary course-correction to the dominant narratives surrounding Ai. This book is not just for AI skeptics but for anyone who wants to engage in a deeper, more nuanced conversation about the technology shaping our present and future. If we are to meaningfully confront the challenges AI presents, we need more books that challenge us to think critically, demand accountability, and advocate for more just and equitable technological futures. For those of us who engage with AI,whether as artists, researchers, developers, or critics, Atlas of AI should serve as a wake-up call. Too often, Ai artists defend the technology out of pride or personal investment, dismissing valid ethical concerns as fear-mongering. On the other side, anti-AI voices often resist engagement with nuance, preferring to frame Ai as an existential threat rather than a tool shaped by human systems of power. Both of these stances miss the point. Crawford makes it clear that the real battle isn’t Ai vs. artists or progress vs. tradition, it’s about who controls the technology, who benefits from it, and who is left to suffer the consequences. If we are serious about the future of art, technology, and creative autonomy, we must move beyond our egos and engage critically with the systems that shape Ai. This book gives us all a foundation to unify under, not in opposition to Ai itself, but in opposition to the unchecked power structures that exploit it and us.

I wish Americans could read Kate Crawford’s book
Format: Kindle
It is a sad bit of irony that the “information revolution” has created a society in which the vast majority of Americans don’t know where their food or water come from. “I don’t get all this talk about drought. You just turn on the faucet and get all the water you want.” It’s no wonder that we’ve created an entire generation of Americans who have no idea where their computing resources come from. “I don’t get all this ‘cost of AI’ talk. ChatGPT is free. Just open your iphone and it will answer any question you have.” While Crawford’s Atlas of AI is a bit sesquipedalian, it is a comprehensive, well-organized, impeccably researched story of where all our miraculous computing power actually comes from. For all the Doomer talk of AI someday making humans extinct, Crawford shows that the way the most powerful American corporations are implementing AI is ALREADY causing vast harm to humans globally, and it will only continue to get worse. Not from some mythical science fiction robot suddenly becoming smarter than people, but from mass ignorance of the slow but steady human-driven global natural resource depletion and exploitation of the most vulnerable people. It’s doubly sad that our polarized culture war politics prevents most Americans from asking the critical questions that Crawford explores in her journey through the landscape of AI creation and production. This book is neither Marxist nor anti-capitalist. It simply argues that, just like there are better ways of managing our water and food resources, there is a better way to manage our computing resources—the first step being a common understanding that there is a natural resource and human cost to every floating point operation that a computer performs. I wish that Americans were able to read, understand, and appreciate such an important analysis of the biggest problem that will confront humans in the next few decades.
