You can also do the outside of the rears, but it will in some cases make the car "loose". Whether you want to do that depends on what your car is doing or what your set up is. For example, when using the 1.0 blocks on the rear, you usually don't want to cyano the rears. when the 2.0 blocks are used, I generally will use cyano on the rears. Cyano when using the 2.0 rear blocks or rear uprights will help the car rotate better.
Couple of other points, using cyano on the inside doesn't do much, but may help in extreme cases. When using cyano on the rears, don't go as far. Carry the cyano short of the treads.
These are just general suggestions only. The amount and how far will vary from car to car and the amount of grip you have at your track. Where I run, we often have to change tires and change the set ups a bit to accommodate the track conditions on that day.
