Spark Racing Technology, maker of the Formula E racing car, will deliver revised suspension components to teams in time for the Miami race, reports electric vehicle and racing website, electricautosport.com.

The uprated parts come in response to a succession of DNFs resulting from collapsing suspensions. The problem could lie in the weight of the cars (they are a lot heavier than single seat racing cars with similar power outputs), in the fast track development process (where testing did not encompass the type of rough, bumpy street circuits that the series visits) or cost control (a big element of Formula E, which ruled out carbon fibre suspension parts).

“We will supply successfully tested reinforced rear pushrods and upper front wishbones for the next race,” confirmed Theophile Gouzin, technical director at Spark.“Next year’s upgrade will focus on battery cooling and performance. We are also looking into brake temperature management to improve initial bite and controllability during braking,”
