Stoptech Cross-Drilled rotors are 1-piece, drilled, 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. 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, Stoptech Cross-Drilled covers more than 2500 applications, all machined in Stoptech Cross-Drilled California manufacturing center. Every Stoptech Cross-Drilled rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

 

Most Stoptech Cross-Drilled rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Stoptech Cross-Drilled 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.

 

Every Stoptech Cross-Drilled 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.

 

Stoptech Cross-Drilled 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.

 

Stoptech Cross-Drilled 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.

 

Stoptech Cross-Drilled 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 Stoptech Cross-Drilled'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 Stoptech Cross-Drilled's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Stoptech Cross-Drilled'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).

Simple sheets at the right price
Color: 01 - Dark Grey, Size: Twin
Pretty good. I'm picky about softness, and I find these comfy. They are a little on the thin side, but for the price they are totally worth it! Ive purchased 2 different sizes now over the past few months.

Nice
Color: 18 - Teal Blue, Size: California King
Just received, washed them and put them on the bed. First time sleeping on them and we really like them. The teal is a beautiful color, they’re soft and feel comfortable, not hot. It was a little hard to put on the fitted sheet but they give you plenty of coverage with the California King. I told one of my sisters about them and she’s planning on getting some. They’re a great price.

These sheets are super nice! The color is on point, and they’re very soft and breathable. There’s a memory foam topper on top of this mattress and it fits over them both perfectly! I would definitely recommend these! 😊
