This is an aerodynamic diffuser design for the mentioned RC car. By widening the rear loop mount ("lug") you can adapt to the spacer situation between the capsule and the plate (if the rear tires wear out). The lower pod position requires a smaller spur than a box stock (eg 93T: Tamiya 53104 or 53900)! - print with the mounts (Cura: mount included) - thoroughly clean all mounts before installing - slide on from the back of the engine bay (preferably with the axle and engine removed) - use the front bottom screws of the bay for mounting - slide the rear "eye" onto the center fender mount - the bay plate should sit flush with the diffuser part - feel free to ask questions ;) Show your thanks, by following my social media or making a donation of your choice.
