The shape of the bumper tip has been changed to match the body shell used in the latest racing scene. The addition of ribs to increase the rigidity of the bumper has resulted in more efficient aerodynamics and improved maneuverability, especially at high speeds. The bumper plate has also been reshaped to improve crash resistance.

These engine mounts are specially designed for the O.S.12 engine. They are lowered and allow the engine crankcase to sit right at the chassis level contributing to a lower center of gravity.
The cooling fins on the sides allows the engine to better dissipate heat and help prevent overheating during a race.
(Do not use with non- O.S. engines as the crankcase and chassis may interfere with each other.)
