Getting good reviews from others but not from me. At least not for my setup. I have the CRX M05 and I had issues with this. I'm using with yeah Racing Chubs and when I bolt down the wheels they don't spin. Seems the wheels sit right on the arm. I know its an easy fix by getting wider hexs but they could have been tested better to avoid this issue and not having to spend more money. otherwise nicely CNC'ed and finished.
very nice looking fit good. you have to use shim on the top and bottom to have a sung fit with the yeah racing C hub. douse not come with any screw or fitting but you can use the same bearing that plastic one have.
