This is a brass weight and carbon body mounting kit for the Plafit 1700KSLP chassis and is intended for professionals and top amateurs. The black chassis plate shown in the photo is for reference only and is not included. All brass parts shown are 1.5mm and the same thickness as the chassis plate. You will also note the motor hole infill piece to provide the counter weight balance for the Proslot motor. The keyline cutouts represent areas that can easily be removed if you wish to reduce the weight in these key areas to balance the setup. The weight kit was widely used by the top finishers at the 2008 IMCA World Championships and 2009 EEC Endurance Championships. Also included are two 1.0mm carbon body mounts and rear axle spacer plate. Note: This kit requires above average building skills and may not be suited to some amateurs.
