Inside Line Racing have released a new 4mm thick carbon fibre shock tower for the rear of the PR SB401. The tower features revised inner camber link positions which moves the group of holes down by 3.5mm. This provides the ability for increased rear traction and stability. In addition to the two existing upper shock mounting positions, there is a new outer hole to allow the shock to be stood up more giving increased forward drive when necessary and allow further tuning.
