Schumacher Atom 40mm fan mount
Coming from Schumacher and designed for the Atom GT12 car is a 40mm fan mount kit. The use of a motor cooling fan significantly reduces motor temperature, allowing the timing or gearing to be increased, therefore resulting in more performance. Weight in the rear area of the car also gives improved forward drive and rear stability and the kit was used to win the 2018 BRCA National Championship. The 3-D-printed mounts come including mounting hardware with the optional fan not being included in the set.
