This works great for me with the 8.5 or 17.5 motor. It balances the chassis and helps to reduce body role with the proper shock settings. When you add weight you need to increase shock damping and spring rates. I still have adjustments with the LIPO in the battery tray to help with tuning for track surfaces. high bite I place the battery forward. On lower traction surfaces I need to shift the weight back.
