What does it take 6WD/8WD to be successful?

[IKE]

Step 1: Figure out what you want it to do.
Step 2: Figure out what it takes to get it to do what you want.
Step 3: Figure out how to make what it takes.
Step 4: Adjust your strategy if you can't make what it takes.

Most successful designs follow this process. One of the most successful strategies/designs ever was drive fast, drive straight, have amazing pushing ability, hold position.

So Tee? What would you like your 6x6 or 8x8 to do?

I would give you drastically different advice depending on the game. While our chassis from 2006-2008 look very similar, they have very specific attributes that were very specific to the games those years.
