034 Motorsport - 2-Piece Floating Rear Brake Rotor 370mm Upgrade Audi B9 A4/S4/A5/S5/Q5/SQ5 - GREY.

The 034Motorsport 370x22mm 2-Piece Floating Rear Brake Rotor Upgrade for B9/B9.5 Audi A4/S4, A5/S5, Q5/SQ5  is a complete replacement brake rotor and caliper carrier kit, designed to work flawlessly with the factory rear calipers. Weighing in at approximately 15.1lbs, each rotor reduces rotational weight by 1.6lbs on each corner over the factory 16.7lbs rotors, and increases rotor diameter from 330mm to 370mm! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture heat, while utilizing 36 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

The 034Motorsport 370x22mm 2-Piece Floating Rear Brake Rotor Upgrade is available in Black, Red, and Grey for the A4/S4, A5/S5, & Q5/SQ5.

The 034Motorsport 370x22mm 2-Piece Floating Rear Brake Rotor Upgrade for B9/B9.5 Audi A4/S4, A5/S5, Q5/SQ5 is a complete replacement brake rotor and caliper carrier kit, designed to work flawlessly with the factory rear calipers. Upgrading your rotors will increase overall braking performance in street, track, and HDPE driving conditions, as they keep your brakes cool and strong all day long!

Weighing in at approximately 15.1lbs, each rotor reduces rotational weight by 1.6lbs on each corner over the factory 16.7lbs rotors, and increases rotor diameter from 330mm to 370mm! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture heat, while utilizing 36 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

Upsizing the rear rotor size from 330mm to 370mm repositions the caliper further outward, increasing its leverage on the rotor. With this added leverage, the factory rear caliper can generate more braking force at the rear axle. This not only improves rear-end braking performance, but also helps take stress off the front brakes during hard stops. The result is a more balanced braking system with better stability, reduced front brake overload, and enhanced overall stopping confidence.

The central hat portion of the 034Motorsport rotor is made of 6061-T6 aircraft specification aluminium. The disc is constructed out of a proprietary metal alloy that can withstand immense braking temperatures while holding form. The rotor utilizes 36 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

The face of the rotor utilizes J-Slot slots to clean the pad surface of contaminants and allows hot pad outgassing.

The rotor and hat have a floating mount system that utilizes high-strength alloy steel bobbins. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat.

Works well, good price.
Color: Arctic White
Effective, fast charging. A little big and heavy but still lighter than a standard Mac charger. Works on my Macbook and my android. Got my Macbook from 0% to 50% in about 30 minutes, while I was using it.

Reliable and Convenient Fast Charger!

I recently purchased the 100W USB-C Charger from Anker, specifically the PIQ 3.0 Compact and Foldable model, and I must say that it has exceeded my expectations in several aspects. Here's why I believe it deserves four stars: First and foremost, the charging speed is impressive. With 100W of power, this charger is capable of rapidly charging a variety of devices. Whether it's a smartphone, tablet, or even a laptop, the Anker USB-C Charger gets the job done quickly and efficiently. The PIQ 3.0 technology ensures optimized charging for compatible devices, saving me precious time and keeping my devices ready to go. The compact and foldable design is a standout feature of this charger. It takes up minimal space, making it perfect for travel or everyday use. The foldable prongs allow for easy storage and protect them from damage when not in use. Its lightweight and portable nature make it convenient to carry in a bag or pocket, ensuring I have reliable charging wherever I go. The build quality of the charger is top-notch. The materials used feel durable and sturdy, giving me confidence in its longevity. Anker is known for its high-quality products, and this charger lives up to that reputation. I appreciate the attention to detail in its design and construction. Another positive aspect of this charger is its compatibility with a wide range of devices. Whether it's USB-C or USB-A, this charger can handle it all. The versatility it offers is a definite advantage, as I can charge multiple devices simultaneously without the need for separate chargers. Anker's commitment to safety is evident in this product. The charger incorporates multiple safety features, such as overcurrent protection, overvoltage protection, and temperature control. This gives me peace of mind knowing that my devices are being charged safely without the risk of any damage. While the Anker 100W USB-C Charger has exceeded my expectations in many ways, I feel there is room for improvement. The inclusion of a USB-C to USB-C cable would have been a nice addition, as it would provide a complete package for charging devices. Additionally, a travel pouch or case to keep the charger and cable organized during travel would be highly appreciated. In conclusion, the Anker 100W USB-C Charger, PIQ 3.0 Compact and Foldable model, is a reliable and convenient fast charger that delivers on its promises. Its impressive charging speed, compact design, and wide compatibility make it an excellent choice for anyone in need of a powerful and portable charging solution.

Great charger, works as intended.
Color: Black
Works great, I’m able to use my Legion Go S docked to my TV with this charger whereas a 65W charger it would slowly discharge. Highly recommend for PC handheld users.

An excellent companion for my Galaxy Tab S9,
Color: Grey, Color: Grey
I'm experimenting with replacing my Windows PC with a higher end tablet. so I wanted a docking station (let's call it the DS) to connect it to a mouse, keyboard, and most i importantly, my 28 inch display screen. So Far, So Good! This review is going through the docking station, the S9, and DEX, then displayed on a nice big screen! I REALLY like using a REAL keyboard! Once it was delivered, I rushed to my workstation to see how it worked. And it didn't! Nothing, NOTHING would work. It kept telling me to check the cables. So out of frustration, I had lunch. It turned out that the case I bought for the S9 fooled me into thinking I had the DS plugged into the tablet, but it was not. Once I had figured THAT out, the docking station, and the tablet worked well together. I like that I'm using two different RF Dongles for the keyboard and mouse plugged into the DS. I don't have to use battery power to use Bluetooth for those accessories. Plus, I still have one USB 3.0 port free. The Keyboard and Mouse don't appear to lag, at all. If it does, it is so minor that I am unable to percieve it. I like that I can power the Tablet from the DS. I'm using a 20 watt Amazon charger, and it seems to work just fine. The tablet doesn't give me any messages that I'm on a slow charge and it seems to charge as it does without the DS. The only real negative is that the cable from the DS to the Tab S9 is a bit too short for the tablet to be propped upright. The tablet display remains on, and the S Pen can be used with it. I'm thinking that I might want to use the tablet itself as a sort of touchpad sometimes. I might find applications where I would want the tablet display to remain upright. I don't know, but it MIGHT be a problem, maybe. Build quality seems good. I think the DS case is metal, at least it looks and feels like aluminum. And the cord going to the Tablet seems quite robust. I can't comment yet on reliabiy, It will take some time for that info to appear. But functionally, it is everything the seller claims it is. I am satisfied. Edit: I bought one for my wife.
