So I've heard ups and downs about aluminum caster blocks/carriers etc. Besides the price point. So Should I or Shouldn't I? I got 100 bucks in gift cards to my LHS Thinking about toughening up the 4x4 pede. Normally I never replace anything until it breaks but my ride is out of commision while the esc is in the shop so I need some projects. Let me know your favorite Beefy upgrades. I'm thinking alum carriers, etc and some better axle/drive shafts maybe?
