[Never enough]

I don't remember if the top is indented also, but if it is, you need to cut 1 coil so both ends line up in the pockets, called "clocking". 1/2 coil is going to cause issues, squeaking and possibly the spring sliding into and destroying the shock.

Also, if the top of the spring is "sqaured off" meaning it lies flat on the frame, I would consider replacing with correct lowering springs as after it's cut, the sharp end of the spring will rest unevenly on the frame pad and can cause the same issues as not taking a full cut on a clocked spring.
