Tower. Moving the shock in on the tower will make the shock feel more progressive i.e.; initially it will feel softer, but increasing in stiffness as the shock compresses. If the track is slippery, move the shock in on the tower to add body roll and overall traction.
Moving the shock outward will make the shock feel more linear. This will free up the car and make it jump much better. On a track with lots of grip, move your shocks out on the tower to reduce body roll.

Arm. Moving to a more inward shock location on the arm will make the buggy feel softer and less stable. For blown out tracks, this adjustment will help navigate bumps and ruts without hurting the car’s jumping performance as much as moving the shock inward on the tower.
An outer shock position on the arm will make the car rotate more during cornering, and make the buggy feel more stable. This comes at the expense of rough track performance.

SHOCKS
Shock Oil. Thicker shock oil will help the car to navigate larger jumps and bumps since the oil will slow the reaction of the shock. In hot weather, increase the weight of your shock oil to maintain the same damping characteristics.
Thinner shock oil will allow the shock to react more quickly, and help your buggy soak up smaller bumps and track imperfections. If your buggy works well in warm weather, switch to thinner shock oil in very cold conditions.
Mark explains, “Temperature is a huge part of choosing shock oil.”

Shock Pistons. Choosing the correct shock pistons is quite simple. On smooth tracks with big jumps, Mark suggests using smaller pistons to slow down the shock action. On rough tracks with fewer jumps, reach for pistons with larger holes to allow the shock to soak up the ruts.

Shock Springs. Mark doesn’t often change his shock springs to adjust his car. In fact, he suggests changing both the front and rear springs at the same time to maintain the same balance front to rear. If the track surface is slippery, go to lighter springs to create more body roll and slow the car’s reactions. On asphalt, grass or Astroturf tracks with tons of grip, use heavier springs at both ends of the car to resist traction rolling
