1/4 rc car project twin brushless motor

Hello

The diffs that I intend to use are similar to the diffs of the photos, I saw these pictures on the net and you can get an idea of ​​their size,The diffs of the flux are not meant to take on so much weight and on this car(27lbs) I do not believe that the flux diffs could last to long!
About the weight distribution I will try to move forward the lipos 3 inches and the motores 2 inches which is the maximum that can go.
