BMW G8X adjustable Rear Upper Arms (RUA) are an absolute necessity to maintain proper rear camber and reduce tire wear on the street and track. The stock BMW setup has an aggressive camber curve through bump travel, which is very apparent on lowered cars. Excess negative camber causes premature tire wear on the inside edge, and reduced traction on acceleration while too little camber will limit rear grip while cornering. Our Rear Upper Arms provide a wide adjustment range for precise rear camber alignment that is easily optimized for street or track driving while eliminating bushing deflection with smooth articulating Teflon lined rod ends in place of the soft factory rubber bushings. Our kit replaces the factory links commonly referred to as the rear wishbone and rear guide links.BMW G8X Rear Upper Arms include gun drilled 6061-T6 Aluminum traction links to reduce weight, as well as a 6061-T6 Billet Aluminum curved rear upper camber arm that are Black Anodized to prevent corrosion and provide a durable finish. Our exclusive 360 degree 6061-T6 Aluminum Rotating Clamp design allows for quick, precise adjustment on the dogbone, while our curved upper arm utilizes our innovative double adjuster design that allows for easy and precise camber adjustment without removing the arm from the vehicle. Our Clamps tightened down with Blue Anodized Titanium Socket Head Cap Screws gives easy access to adjust camber settings, shaving off even more unsprung weight without compromising strength.This Part Fits:

Does exactly what you need it for.
I like these adapters.
Some pros:
* There's a blue light to show that power is coming to the adapter (great to ensure you've plugged it in correctly)
* The gap at the bottom of the plug ensures that it works with a phone in a case. (I tested it on an iPhone 15 pro max)
* The connectors are solid good click when connected.
* The housing is solid aluminum (no flex or seams, etc)
* There is a little label on each that shows how much power or data can go through it.
Use case:
* Allowing you to use your phone on your bed while the phone is sitting on your chest (and still plugged in)
* For the USB-C to female USB-A female adapter, the page shows that you can use this to connect a flash drive or a regular USB-A cable with the other end going to your peripheral (like a keyboard or game controller)
Overall, this is a great item to own in your gadget bag.

They work.
They work fine for my sort of "specialized?" use. By relieving the strain on the laptops USB ports. Hopefully, prolonging their lifespan.
Do wish they would make the edges and corners a bit rounded.

I can use my remote again
Style: 1 to 1 IR Repeater
I added a center channel speaker, and it was partially blocking the remote sensor. This solution works like a charm and has an easy setup. One end points towards the existing IR, and the other end goes where you are going to point the remote to.
The only suggestion is to include a USB connector with the product, so I don't need to find one.

Very good signal repeater
Style: 1 to 1 IR Repeater
Fantastic product! I have a center channel for my surround sound that blocks the infrared sensor on my Sony Bravia TV that never works. I always have to get up to turn the TV on or off as well as other functions. So I purchased this product and it worked like a charm. Very simple to install, took less than 5 minutes . I didn’t have no compatibility issues. It was plugged play . Simply stick on the transmitting sensor by the receiving sensor on the TV and then the extended sensor for receiving from your remote control put where you would like it, lastly plug in the USB plug into any 5V power block and you’re done. Now I have no issues with range with controlling my TV, which is great.!👏🏼. Definitely a good product. I would highly recommend…

Easy to Set up
Style: 1 to 1 IR Repeater
Works great. Have Sonos playbar mounted behind TV and it does not support eARC, only IR, for use with AppleTV remote. This solved problem.
