 Power Slot Rotors

Power Slot rotors are 1-piece, slotted, direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer. Launched in 1998, Power Slot was the first premium slotted replacement rotor program in North America. Innovations include e-coating, double-disc grinding, full machining, mill balancing and center-split castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy. Today, Power Slot covers more than 2500 applications, all machined in Power Slot's California manufacturing center. Every Power Slot rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

Most Power Slot rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Power Slot has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.

Power Slot rotors feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction, or "bite", amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions.

Every Power Slot rotor is finished with a black e-coating on both sides of the hat, inside the cooling vanes and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral runout issues.

Power Slot rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad and rotor break-in. This special finish also provides quieter and smoother stops.

Power Slot rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

Power Slot brake rotors are mill balanced to a tolerance of less than 2 oz-inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth, confident application of braking force.

Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.

Power Alloy metallurgy is another unique feature in many of Power Slot's rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Power Slot's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Power Slot's top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum promote crack resistance and improve noise, vibration and harshness (NVH).

"Racial Capitalism"
Format: Paperback
Cedric J. Robinson’s Black Marxism is first a history of Black people appearing in historical texts as far back as Herodotus (c. 484 – c. 425 BCE) in ancient Greece, and second a history of “the collisions of the Black and white ‘races’ beginning in the fifteenth and sixteenth centuries.” Robinson’s thesis connects the evolution of capitalism to its roots in racism (racialism) understood in broad terms to comprise the subjugation of one class/group/nation/race by another (the Irish by the English in the nineteenth century, for example). He uses the term “racial capitalism” to express this process—the necessity of opposing classes for the function of capitalism. As a result, “racialism,” he says, “would inevitably permeate the social structures emergent from capitalism.” Keynes attributed the slow change in the “standard of life of the average man” until the beginning of the eighteenth century to “the remarkable absence of important technical improvements and to the failure of capital to accumulate.” Capital is accumulated, in Marx’s view, through the accretion of “surplus labor” which is the extra time a worker “must add to the working time necessary for his own maintenance . . . in order to produce the means of subsistence for the owners of the means of production.” Robinson ties capitalism’s early exploitation of surplus labor to slave labor and the slave trade noting, “historically, slavery was a critical foundation for capitalism.” Robinson traces the forced transport of Black people from Africa (the diaspora) to Europe, as well as Central, South, and North America as a foundation of early capitalism (and slavery as its form of “primitive accumulation” of capital). In his discussions of slavery, Robinson stresses the sense of the enslaved people with respect to their captors in terms of the slaves’ resistance, hostility, and defiance of the masters—their “Black radicalism.” As Robinson’s text approaches the twentieth century and the influence of Marx, his focus narrows to the significance and character of specific Black leaders including W. E. B. Du Bois, C. L. R. James, and Richard Wright and their respective connections to Marxism’s diverse interpretations. Marxism, says Robinson, “has proven insufficiently radical to expose and root out the racialist order that contaminates its analytic and philosophic applications or to come to effective terms with the implications of its own class origins.”

Any socialist movement must centrally address racial liberation to succeed.
Format: Kindle
Robinson's masterwork powerfully demonstrates how the Black radical tradition emerged from the shared experiences of resistance to racial capitalism and colonialism. By tracing this intellectual and political lineage through figures like W.E.B. Du Bois, C.L.R. James, and Richard Wright, Robinson shows that Black liberation struggles were not simply an offshoot of European socialism, but represented their own distinctive radical tradition. A key insight is how Black resistance movements developed theoretical frameworks and modes of struggle that went beyond traditional Marxist analysis. Where European Marxism focused primarily on class conflict within industrial capitalism, Black radical thinkers recognized that racial oppression was fundamental to how capitalism developed globally through colonialism and slavery. This more comprehensive analysis helped explain why racial liberation had to be central to any meaningful socialist transformation in the United States. The book compellingly argues that Black liberation movements - from slave rebellions to civil rights to Black Power - represented some of the most significant challenges to American capitalism. These struggles exposed how racial oppression was not incidental but essential to American economic and social relations. By fighting for racial justice, these movements struck at the foundations of the capitalist order itself. Robinson's updated edition strengthens these arguments by extending the analysis into more recent decades. He examines how Black radical politics evolved in response to neoliberalism and continued racial inequalities, while maintaining connections to earlier traditions of resistance. For readers interested in both racial justice and socialist politics, this book remains invaluable for understanding how these struggles are fundamentally interconnected. It demonstrates why any socialist movement in the United States must centrally address racial liberation to succeed in transforming society.

A Classic That Requires Time
Format: Paperback
This book is for a particular type of reader. Robinson’s writing is beautiful, but not easy. The ideas are complex. It takes effort to get through. But, if you are interested in Black politics, and looking for fresh thinking, I recommend it highly. The funny thing is, the title is misleading. It is more about Europe and the formation of capitalism, and what Robinson defines as The Black Radical Tradition. Marx is critiqued but not rejected, and held uneasily at arm’s length. As Angela Davis wrote, this book needs to be read more than once. It’s like an album or a movie that is so unique and rich that you know you probably missed something on the first go-round. I expect to return to it many years to come.
