This new hard type main chassis (G053) for IF15 was recently used to take the win at the 2018 World Championship in Miami. Featuring a stiffer rear section both traction and response is increased compared to that of the kit version.

New for the IF15 this special hard coated clutch bell is a direct replacement to the standard version. Light and extremely durable it also offers great clutch bite. As used to win the 2018 World Championship in Miami.

These innovative clutch weights sit between the flywheel pins and offer a higher clutch meet than a normal type weights making them suitable for use with basic engines such as 12TG from OS. Set screws are included to adjust the weight and clutch meet pressure. Also usable for high power engines.

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.)
