Serpent is introducing some new parts for the Serpent Viper 977-EVO at the 2016 EFRA EC in Sweden, which will be introduced before end july worldwide. The new upgrade set moves the lower inner rear pivot pins closer together. With the application of longer pivotballs the lower suspension arms are made longer. This package creates more traction overall, so higher corner speeds are possible, and a more stabile rear end under braking. Image of the prototype parts as attached, as well as the assembly and mod instruction. Serpent also introduces the low friction pulley-set at the EC, and also this set will be introduced officially in the next weeks.
