RX28 Short Upper Link Knuckle (Extra KPI) Set (left/right) [Reflex Racing] RX28A-65This knuckle offsets the top ball thread location by 0. 25mm inwards. This creates a shorter upper arm and increase camber gain on your front end. A shorter link makes the reaction of the car slightly faster for conditions where you are looking for higher response like short tracks with tight corners. This Setting effectively increases KPI. This knuckle set is easily identified by having 2 dots cut into the steering arm.

Comfy but cheaply made. I bought these for the price and expected them to be not the best quality but they are even less than I expected. Please also note that they run small. I got a 10-11 since I wear 11 shoe and Amazon recommended this size. I think a size larger would have been better. Not worth returning though. I’ll just wear them this winter if they last that long and get a better brand next time.

Quality and comfort

Size: 10.5-11.5 Women/9-10 Men, Color: Black

Comfortable and fit well. I got these to replace a very old pair that finally wore out! Warmth is medium (I wear puffer booties for when it's really cold). Quality on these is great!

Can't go wrong with Acorn for as long as they last!

Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal

Acorn is just a great company all around. I had bought my husband these slippers over 20 years ago. They are still in great shape although the sole has worn in some places. But nothing's coming apart! However, I decided to replace them for him. His foot is 10.5 and they are a little hard to get on right away-of course, after over 20 years of having "worn in" the original pair, anything would feel tight. So I'm not holding this against them. They will relax with use. The only difference is that the original sole was black and these are tan. I think I would prefer the black, but since it's only being worn in the house, no big deal. My husband has really cold feet and these slippers never fail to warm his feet right up! He said they feel really soft to walk in and like the cushioning. They're not too heavy and fit him great! I have Acorn slippers myself that I've worn every single day in the house and outside to the mailbox too. They last.

Very warm and comfortable. A little difficult to put on with the collared top.
