I am wanting to install gauge rings in my 95TT. Gza doesn't have them any more, so it looks like czp and Z1 are the only sources to get them. I have read that the Czp rings (brushed aluminun)have to be glued in place and that the Z1(chrome) rings fit without glue. Can any of you guys comment on the one you have. I think I am going to go with the Z1 rings.
