I won't speak for them directly since I didn't pack the container
. But generally kits and parts are shipped together. Support should be up to your local hobby shop and HRP the us Distributor.
In general the kids contain a base setup of oils and lubes for the kit setup. I'll see what I can find on included wheels,etc.
The car should be rolling on 14mm wheels so you'll need to run those unless you swap to the older 12mm hex which I'm told is easy to do. Then you can run 12mm buggy wheels from Durango and others.
