Weight lost
It is extremely easy to waste weight, and every builder with common sense will tell you that.
What you can use to waste weight:
-Ballast (unless you are using them in front to create a better wedge).
-Heavy weapons like the Sledgehammer
-6WD RAD drive (4WD is bad too).
-Big wheels (GrannyGuard Wheels should be big enough for all your needs. Try to always use Shiny Hub Wheels if you can.).
-Steel armor (Or titanium armor. Always use DSA if you can, and plastic if you need the weight).
-Bad use of extenders (Using a lot of angle extenders can really eat up a ton of weight. Try to use a minimum of extenders when building).
