RE: PX III Track Tensioners
I would get the suspension kit, especially when it will be free. It is a copy of the Asiatam set as well and is an easy upgrade. If you are using metal tracks they will help for sure. I have attached the install photos and a pic of the parts. You will notice I changed the chain holding the tow shackle in place to a more scale size chain. You can see the original chain in the parts pic.
