S13 Wisefab knuckle has revised kinematics when compared with OEM and built in anti-squat

All the metal components our wide version of A90 rear suspension are made from high strength steel

much like how an electronic throttle body is controlled and the strategy is as good as your imagination and your ECU or controller will allow

The top arm front pickup point is raised by 40mm for better antisquat

it has to be sourced from BMW E90
