These shoes are replacement shoes for the stock Kyosho flywheel. These shoes run the special m2c torsion spring which allows
Us to have a flat faced clutch shoe instead of a slotted shoe which adds more contact surface and doesn't transfer heat to the springs.
We include a set of 1.0 springs in with all as this is good start point.
Optional springs for different track conditions:
9000 (red) .90
9001 (yellow) .95
9003 (green) 1.05
