I’ll start: put a lot of your mass low, because the increased traction makes you tippy if you’re top heavy.
Also, instead of braking to make a tighter turn, just let go of your gas for a second. Will give you that short radius without sacrificing too much speed.
Build wide. 14 blocks. Tracks need a wide base. Use weapons that are hard to shoot and benefit from track stability and fast turning radius. Fortunes or Yongwang come to mind.
Using the smaller tracks as frontal armor works great if you use other movement parts that lift them off the ground. I have a quad auger build with tracks on the front. I’m not sure there is better armor in the game. I’ll have to look.
