The stabilizers go through the base of the limbs at the front of the bow. There are 3 limb factors, one goes through the stock in front of the cables, the other two go on the limbs. Two string factors go in the string.
As with almost any noise dampening system there are trade off's. You will loose a few f.p.s. with the limb factors and string factors installed. You can choose not to install them or install them and loose a few f.p.s.
The stabilizers and the limb factor through the cable slot really help out and I don't see the need for the rest of the kit. You won't loose any f.p.s. that way.
