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.

An interesting look at capitalism in the US
Format: Hardcover
Seller: Product arrived on time in good condition. No issues with the seller at all! Book: This is a pretty dense history of the US through the lense of capitalism. There are quite a few editing errors (typos, incorrect quotation formatting, etc) that are speed bumps to the flow of this book but don’t ruin the reading experience. There are also a few moments where a subjective claim is made using a historical event as a backdrop, but the claim isn’t elaborated on as well as it could be. I chalk this up to the focus of the book being on history and not economics, but I do think if a claim is made it would be interesting to have more data as to why the claim was made.

Marx had the proletariat, Mao had the farmers, America has the owners of financial capital
Format: Kindle
What makes Jonathan Levy’s book so informative is that it is truly a parallel history of its politics and its economics. And only by viewing these two intertwined paths side by side can you truly understand the myth of the American free market. America’s politics and its economics have never, since the country’s founding, been separated. The state has been an integral part of everything economic to an extent that would make the most rabid socialist gasp in horror. The only difference is that while the Marxist state stood side by side with the proletariat, and Mao built the number two economy in the world on the support of farmers, America built its economic marvel on the backs of, and for the benefit of, the owners of financial capital. That’s not all bad, mind you. It takes workers, farmers, and the owners of capital to build a modern economy. The tension comes when there is a lack of balance between the importance the state attaches to each. And there can be little surprise that America’s politicians have put the owners of financial capital at the top of their list of priorities. Politicians, after all, can do nothing without power, and power comes via the electoral process, a process that is today fueled by obscene amounts of money. And who has all that money? The American economic narrative is a misleading tale of meritocracy and free markets. The Horatio Alger-based myth is that you are only limited by your skills and your ambition. And like most enduring myths there is a thread of truth to it. Many successful people truly deserve what they have achieved. But does anyone really possess $150 billion of personal merit? Can we statistically accept that the wealthiest nation in the world is also one of the most financially unequal without seeing a pattern of bias? Perhaps the most selectively quoted book in history is Adam Smith’s “Wealth of Nations”, published, strangely enough, in 1776. Often credited with being the father of capitalism, Smith argued that markets free of excessive regulation would be more efficient than markets that were overly regulated, although Smith “made no categorical separation between the political and the economic, or state and market.” Smith did, however, warn against the socially destructive power of monopolies, which unregulated markets will not protect against, and he correctly predicted that the excessive division of labor would lead to a degree of labor and wealth inequity that would destroy society. At the time when US Steel, General Electric, and General Motors, among many others, were the power behind America’s global economic hegemony, most Americans earned a living through wages. And those wages were made possible by long term fixed investments that created jobs. They were generally big bets that took a long time to earn a return but that aligned with the jobs-first priorities of most companies. (Employees first, communities second, shareholders a distant third.) And while not every employee enjoyed the same salary, the differences between the top earners and the average earners was a fraction of what it is today. That era, of course, is long over. The current economy is geared toward the creation of wealth through the short-term investment in assets that will appreciate rapidly and are highly liquid. At the moment that is the stock market and synthetic financial tools pedaled by hedge funds, banks, and the like. The problem is that the wage market encompassed much of America. The asset appreciation market encompasses only a tiny sliver of the richest among us. There is spillover, of course. The lawyers, analysts, consultants, bankers, and sales people who serve the asset appreciation market are doing quite well. But the man or woman who has less education and who might have made a decent living in a steel mill or car assembly plant, has lost out. And despite what the politicians will tell you, the gap is getting wider. (I spent a career in corporate industry, have a college degree in economics, have been a CEO, and have served on four public company boards. I know enough to know that Levy knows what he’s talking about.) The second important point to come out of all this is that economics is not really a “science” as most people think of that term. There is a shared jargon and there are commonly accepted principles. The very idea that there is an economy that is distinct from all other aspects of human existence, including the state, however, is a relatively recent concept. The weakness of the distinction, in fact, is clearly demonstrated by the remarkable reality of just how diverse the history of the American economy is. The sun doesn’t always rise in the east in the world of economics. In each of the economic eras Levy describes it is stunning how few people actually formulated the thinking that defined them. I will join some of the other reviewers in suggesting that the author could have spent more time explaining some of the jargon inevitably found in a treatise on economics. The layman obviously wasn’t his target audience but the book, I believe, could have read more smoothly and been much, much shorter. (The editor and publisher have to take some of the blame for this.) Even if you have to slog your way through the more tedious sections on global capital flows and such, however, you’ll get something from the book even if you’ve never set foot in an economics classroom. If you get no more than the fact that the free market is a myth and that most long term capital that actually creates jobs and income for the average American is actually provided by you, the taxpayer, not the Wall Street capitalist, you will better understand why there is so much division in our country right now. We don’t have a democratic economy. The young wonders of Silicon Valley would have nothing if it wasn’t for your tax dollars and your pension plan, if you’re still lucky enough to have one. We can do better. We have to. The economic inequity we have now is simply not sustainable.

Very impressive analysis. Unfortunately the author ended his analysis in 2010. Wish he had offered some thoughts on what should be done as opposed to what is being done in this age of economic chaos.
