The voice coil shim supplied with the kit was 0.010" thick but it would not go into the gap. I found that I had to use a 0.008" shim (0.009" did not work either. I got the shims from a machine shop supply company. I also did the voice coil to cone before the voice coil wires, not after and added a glue bead, spider to voice coil (around the outside). Other than that the kit looks great and the adhesive kit that is recommended also worked well. Speakers sound and look great.
