Cross-Drilled & Slotted Rotors

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

Most Stoptech Cross-Drilled & Slotted rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Stoptech Cross-Drilled & Slotted 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 & Slotted 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 & Slotted 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 & Slotted 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 & Slotted 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 & Slotted'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 & Slotted's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Stoptech Cross-Drilled & Slotted'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).

Accutane holy grail!!
I’ve been on accutane for 2 months and have used this day and night. My skin has not flaked once and has appeared so hydrated despite taking a very drying medication! It’s very lightweight, non-stick, and quickly absorbs into my skin. I don’t usually write reviews but this is worth while for accutane users!

Great product but pricy
I really like this product. It helps with “aged” skin- moisturizing but not oily or heavy feeling. It is pricy though.

Perfect for Glassy Skin
Love the feeling, ease of application, hydration, longevity/ duration, and all-day effect. Would be nice if they cost less, but here we are. Size is perfect for travel. Of course super hydrating products will be a bit sticky to touch, but I shouldn’t be touching my skin anyway. Only pops up when I need to put my face down for a massage or at the chiropractor. Love Avéne!

Hydrating serum
This product is not as hydrating as it claims for my 56 year old skin. I have to reapply several times a day. There's no irritation or stickiness which is great tho.
