With this tool and suspensions, you will be able to replace kit suspensions with molded spring with your own made: Use the tool to bend in shape a 0.3 to 0.5mm copper wire, that can be pre-colored or to be painted, and apply it on the provided suspension parts, that are made long enough to cover all type of needs, just trim them down to the size you need, paint, assemble and glue!
 
Wire not provided in the set.
