T.O.P. Photon EX shims & outdrives
T.O.P. Racing have produced two new optional parts for the Photon EX. First up are these shims which allow you to conveniently adjust the roll center without having to remove the suspension blocks. They come as a set of shims with 0.5mm and 1.0mm thickness. Also new are a pair of steel gear differential outdrives. When aluminium can’t withstand the torque of modified motors, or stock motors with speedo timing, hardened steel gear diff outdrives are what you need.
