I recently bought a used 417v5 from and it came with multiple sets of springs. They are all white but on the bottom they are marked with different colored dots on the bottom. In order of hardness by feel- yellow silver blue gold (gold is hardest) I looked at all the spring charts but these colors don't seem to match up. Does anyone know brand they might be, because I have recently been chasing a good setup and would like to know how these compare or should I just throw these in the bin and buy the HPI silvers as I am going to be racing on asphalt?
