Modifications to the Advanced Vehicle Blueprint?

Ive been looking everywhere for tutorials on modifying the Advanced Vehicle Blueprint and I cant seem to find anything. Ive also noticed that lots of other people have been posting similar questions and not had any responses, so I thought I would try and be more specific with my request:

My goal is really to try and get the Advanced Vehicle to drift/skid and wheelspin as it currently just stops instantly when braking. Also I was wondering how to self-level the vehicle in the air to prevent it tipping forward or flipping over to its inevitable doom!

Any help would be greatly appreciated!
