Are Concave or Convex Bumpers Better for Protecting Your Chassis and Gearbox?

When applying a CRP (Custom Racing Products) rear bumper on a ORV (Off-Road Vehicle) chassis gearbox with a gearbox support gear tensioner, like the ones from Skibby's Performance Mods, depending on the direction you place the metal pieces, your white dyeable nylon bumper will either bend outward or inward. In this episode of the RC Deep Dive podcast we check all perspectives to see which of these options, convex or concave, is best for your Subaru BRAT, vintage Lancia 037 Rally, Mighty Frog, Blackfoot, Super Beetle, etc. by using material science and the laws of physics and geometry to give you the best bump for your buck.
