Following the introduction of the AME aluminium top deck for the Yokomo BD8, Ruddog now also announced the release of a T4 2017 specific part. Offering reduced torsional flex compared to carbon fibre parts the upper deck will generate a completely new on-track characteristic similar to an aluminium chassis but it is easier to change while also adding a whole new look to the car. Using the top deck will make for a smoother and easier to control car in a wide range of track conditions while also improving corner speed and it is usable on 2017 edition T4.
