From what Ive read, the Superior Intermediate is too frim. I have the corevette serve and it is firm enough. I am not sure what spacers if any were used in the HD2 kit. After buying my transmission parts and before installing them, my tranny failed on me. So I had it rebuilt with basically all aftermarket parts, and it is now built. 1-2 is a little strong for me, but I am getting used to it. I have only had it since tuesday late afternoon. Probably in a week or so I will be completely used to it and would not bother me.

I dont think I helped your post, but I am just giving my insight.
