RE: basic question
There are two different types of steering (basicly). C-hub and PBS. PBS is more adjustable and supposedly stronger but the C-hub seems to work better for precision steering. There are pros and cons for both, Though if you're new to the hobby I wouldn't worry about it too much. Get the TQ and If you break the steering knucles upgrade to CNC ones.
If you need more info do a search on C-hub and PBS
Hope this helps
