BMW F8X 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 F8X Rear Upper Arms are gun drilled 2024 Aluminum links to reduce weight, then are Black Anodized to prevent corrosion and provide a durable finish. Our 360 degree 6061-T6 Aluminum Rotating Clamp design allows for quick, precise adjustment. 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. Our Rear Upper Links provide superior performance, durability, and ease of adjustment. Long gone are the days of fumbling with wrenches to tighten jam nuts while trying to trying to keep your bearings oriented correctly. FK Spherical Bearings and Rod Ends are manufactured in Connecticut and utilize a Teflon liner to provide quiet operation, lower friction, smooth articulation, and eliminates bushing deflection under load. Sold as a complete kit for one car (4 total arms). Made in the USA.

Nice beach shirt for senior portraits
Color: Light Green, Size: X-Large
I wanted some beachy vibe pictures for my son's senior portraits. He's taken up surfing lately, so I wanted to get a few shots of him at the beach, but I wanted his outfit to work with the scenery. I saw this shirt and I thought he would look good in it. This shirt is really nice on him. It fits his big shoulders well and accentuates his V shape. It's not too form fitting, but definitely doesn't look frumpy. It's soft and light and the sage green looks so good against his golden olive skin. The only qualm I have with it is how much it wrinkles. I know it's a linen blend and they always wrinkle, but I had to make sure he changed at the beach as not to go out with a ton of wrinkles. It's a material problem, not specific to this shirt...but annoying. The shirt launders really well with only a little shrinkage...it made it fit better on him in my opinion. Just make sure to take it out of the dryer promptly and hang it up.

LOVE these shirts, came back and bought more!
These shirts look SO good. I am a senior manager in a large corporation so have to dress nice every day. I loved the first one of these shirts so much I came back and have now bought 15 of them in different colors. Basically, these are now all I wear. Buy yourself 15 bamboo undershirts with the V neck (you don't want the layered look with dress shirts, you want the V neck so you can't see the undershirt), half in white and half in black to wear under these and you are set. GUYS.....WHEN YOU FIRST BUY THESE YOU MUST IRON THEM. I see the pics of people wearing them here, and you can still see the fold lines from being packaged and that looks terrible. Washing alone won't get rid of the fold lines. Get your iron and set it for POLYESTER which is a lower heat setting. If you set it hot, it will melt the shirt. But set it for polyester and the lines iron out VERY easily and fast. You only have to do this when you first buy them. I've never had to iron any of them again after the first time. They are very wrinkle resistant! I HATE my cotton dress shirts now. These Coofandy shirts STRETCH like crazy! You can bend and reach for things no problem. I'm able to wear all of these with Chinos, dress slacks AND jeans so they are incredibly versitile! My wife and my girlfriend both (joking!) love how soft the shirt feels on me. I have to wear these shirts every day and own enough so I can do laundry once every other week and so far all the shirts have been very durable with no tears, rips, any problems at all. They all still look new.

Must iron first before wearing. Then wrinkle free.
The fit is perfect. The material is quite nice. The only problem would be they are hard to de-wrinkle from original packaging. I’ve washed my shirt several times and it’s still showing the creases. The only way to get rid of them is to launder them or iron them. I think once this occurs, they remain wrinkle free for a while. This is the third of the exact same shirt I got in different colors.
