yes, the camber plates do work, but they are 1 pc. So when used with the low profile top deck, it must be spaced up 3mm or at least be combined with some of the Genesis Bulkead brace +1mm of shims. (this is probably the best plan of action.)
We don't have upgrade kits because we are out of hubs. But once we get more hubs in stock, we will make the upgrades available again. I know I have about 10 or so upgraded cars out there that use the new hubs, inset battery and all related parts.
