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).

Highly recommend getting this product.
Color: White, Size: Medium
Great pillow that is worth the money. We travel often as a family and got these and it was worth it. The quality is good and it it firm enough to be comfortable. I got good support and also enjoyed the fact that it can be rolled up into the travel pouch and transported.

If you want an afforable, adjustable pillow - give this a try
Color: White, Size: Medium
I live this pillow. I bought two one for travel and one for home. I'm a side sleeper and most pillows are too fat for me, but my old pillow finally got too flat. It is very light and has an interior pillowcasing with a zipper under the main pillow zipper. Open both and access/remove the shredded foam (?) stuffing material. Be sure to save it in case you removed to much, I ended up putting some back in. It is slightly curved on one long end. It find it very comfortable, and there is no smell from the filling. I'm sensitive to stuff like that. I took off one start, as I wish it came with a pillow case just that size. It fits in a regular pillowcase sort of. The long side of this small pillow fits in the short end of a regular pillow case, but then you have all that extra length hanging over it, I asked my mom to cut and sew a few down for me.

It was by far the best of the 3 I ordered
Color: White, Size: Medium, Color: White, Size: Medium
Good shredded memory foam pillow. Great for traveling. Great for side sleeper. I have had neck and shoulder problems and went through a ton of pillows before settling on Luxome Layr adjustable pillow. But way too hefty to travel with. I bought three travel pillows for a trip I am currently on - this one, a sleep number one and Alkamto travel and camp Pillow. The Alkamto was a no-go right away. Too squishy. Little support. Loved the Nappler. My husband liked it too so ordered him one. I will say his came in and was not as full as mine. I had some leftover fill from my Layr pillow so filled it out a bit for him. He doesn’t need one as supportive as mine so it wouldve be fine. It is nice because if it’s too firm you can pull some filler out. Had I gotten the second first it still would’ve been the best but I’m glad mine was fuller. The sleep number came in the next day and way good but not as good. Gave that to my adult daughter. Returned the Alkamto one as useless. The Nappler rolls up pretty easy and compacts down well in its bag so I could fit in my carry on. Was good for the flight - a long flight with lay down seats but crappy pillows. I’ve used it instead of the hotel pillows and also now the cruise ship pillows. 5 days into travel and I’ve very pleased.

Very comfortable/ Good support
Color: White, Size: Medium
I travel often and I’m always frustrated that I have to leave my good pillow at home. I bought this one very quickly and on a whim and boy was I surprised! I slept very well the first night with it! I didn’t have to make any adjustments to it at all! I like that it’s white and can go inside of any pillowcase. When you take it out of the dryer to initially fluff it, it looks very big, but is extremely comfortable and does not strain my neck at all! It provides excellent support.

Great for Travel - Perfect Size and Comfortable!
Color: White, Size: Medium
After trying to find a neck pillow for travel and many returns, I purchased this pillow. I love it! I have a long and thin neck and all the neck pillows did not provide enough support and constantly rotating the neck pillow does not work for me. Switching to this pillow was my answer. It came compressed and I followed the instructions (15 min in the dryer on low with a couple of dryer sheets). The pillow fluffed right up and is super comfortable and supportive. There is no smell. The cover is very soft (a must!). It easily compresses into the provided bag so easy to travel with. It's also the perfect size, small enough to easily travel with, and large enough to provide support. I recommend it.
