As a result of viewing the video above, calculate the face to face measurement.
  1. Measure the offset wheel. The wheel offset is the distance between the inside of the hub and the outside of the rubber.
  2. Add 50 mm to the offset. Alternatively, choose your own distance between the rubber and the chassis.
  3. Multiply by 2 for both sides. Add your chassis width to the above number.

Axle Flex

A wide 50mm square brakes axle assembly is your solution to axle flex from smaller axles.

Axle Flex will rapidly wear your springs due to the reverberation of vibration from the center of the axle back to the spring.

Effectively, your spring is working twice as hard as it should. Read our article about vibration fatigue.
