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).

Great for AR Glasses
This USB hub has been great for me! It's taken me so long to finally find a stable setup to allow using my XREAL Air glasses, peripherals, and charger at the same time. I've used this both with my phone and ROG Ally and I have not once had a problem. I even found that my ROG Ally manages to get the full supported PD of 65W, as long as I power the hub with a 100W PD charger. That said though, using a 65W PD charger is still more than adequate to charge the device while using various peripherals and a USB-C display. Previously I used USB-C hubs with HDMI out and another device to merge the HDMI output with a USB-A connection into a single USB-C cable that I use for my AR glasses. This setup worked, but would increasingly stutter/freeze the longer I used it forcing me to constantly unplug and re-plug it in. In trying to find a solution that didn't split and merge back the display signal with USB data/power, this hub was the only one I found that wasn't thunderbolt 3/4. I will say that I wish the cable to the host device was either longer and less rigid, or shorter with an optional extension cable. An ethernet port would have also been nice, but using up one of the USB-A ports with a USB ethernet adapter works if needed. Plus, if I wanted ethernet with it, then a dock would probably have been a better option over a hub anyway.

One of the only dongles that supports a usb-c display (alt mode) AND Power Delivery!
If you are like me and have laptop that only has a couple of usb-C ports (one of which has to be used for charging), but want to free up a port, this is the ONLY dongle I have found that does the job flawlessly AND affordably. The dongle has a usb C port. for power delivery as well as a second usb C that not only supports data, but has the necessary specs to support a usb C monitor (via DP alt mode). This is only dongle I have come across that has the necessary hardware to support a usb C monitor for less than 100 bucks.

(Steam Deck Verified) Works like a charm on Dual QHD 2560x1440 (1440p)
This could be one of those reviews where I tell you how well this works for work Zoom Meetings and the Monthly TPS Excel reports. But my primary concern was the Steam Deck my secondary concern was being able to see more work. Luckily it worked for both. The Steam Deck is capable of pushing to both 1440p monitors without any issues. I don’t have many AAA games, but if it helps: Hogwarts Legacy ran at full speed on auto detect (medium) graphics. No ghosting, no tearing, no lag. I tried No Man Sky for something with very high particle and blooming. Still ran like a champ. Mafia Definitive Edition runs like Estes Kefauver at a meeting of Murder Incorporated. If it runs on the Steam Deck this hub can push it… Remember my monitors are only QHD 1440p. One laptop worked amazingly. 1440p Zoom Calls, Excel Spreadsheets as far as the eyes could see. BOTH EMAIL AND CHAT OPEN ON THE SAME SCREEN! *Car salesman roof slap* This baby has so many pixels. The other laptop didn’t support video over USB-C nor Power Delivery. The USB hub worked very well as a USB hub though. The USB ports are all fast and reliable. My USB 3.x devices have varying speeds. I don’t think any device measured the full through put, but given the equipment I have to work with (it could be the equipments fault) I am happy with a 4.8 out of 5. Using the power delivery port on this hub will allow you to charge attached devices. Steam Deck charges, Laptops with USB-C Power Delivery charge. Laptops without power delivery will not charge. The ports with pictures of keyboards, please plug your USB Keyboard and Mouse in these ports. These ports are USB 2.0. They will run slow if any other devices are plugged into them. If your device does not support Thunderbolt, Alt HDMI, or Displayport over USB-C, You will not be able to use the video ports.

Great product, had an issue, they took care of it.
Purchased this to allow me to run one cable to a laptop and have monitor/power/external accessories all connect easily. After a few days I noticed my monitor would disconnect and I would need to unplug and replug the device. Reached out to Anker support and they responded quickly to help diagnose and then sent a replacement unit very quickly. Was seriously impressed with the support and follow up. Item has been working perfectly since - makes a great clean setup.

Worked like a Charm.
So satisfied. I’ve tried using extenders with usb hubs because the cable is too short for my Dj set up but the extenders don’t work. Not sure why. This one worked perfect with my own Dj tech tools green cable.
