I'm not sure exactly on the center pulley shaft but we did talk a while ago about changing it to steel and putting a shoulder on it so you will only need a spacer on one side. This way it doesn't compress/tweak the car after being tightened down multiple times and the shoulder will eliminate struggling with 2 spacers and keep the center shaft from digging into the bulkhead on one side. Just little tweaks to make it easier/better.
Pedro - The optional camber plate is to change the lenght of the camber link. The 1.25mm has in between holes (instead of 2.5mm between holes) from the stock camber plates plus a really long position that I've really liked on the front end of my car....
