I dont mean to be telling stories out of school (quote from "Oh Brother Where Art Thou"). . . But I just finished building my first yokomo cap equipped associated shock, and I gotta say. MAN!!! This is the one and only way to get these shock built. This was THE BEST $26.00 (product plus tax plus shipping) I have spent in a long time. I just had to share my joy. If you've got the $$ and want some suh-weet pushers, this is the only way to go on the TC4.
