Yet another 904 rebuild thread, what kit?
To the op, yes I think the extra clutch or the extra strong friction would make a better hold under severe racing conditions or under severe torque or power but really not going to help anything in the lower range.
We have a couple transmission supply houses here in town so it makes it nice but I would recommend if you have some place close by to do that as if parts aren't correct like mine weren't you can simply drive down and dig through their old stuff like I had to do. Also with what you're talking about and no real dragstrip time to talk about the stock rebuild kit with a nice trans go 2 shift kit will make you plenty happy for a long time. And also when you pull this apart and see how utterly simple it is and your intelligence has been insulted by how simple it was you'll figure that in five to ten years if you had to do it again you'll probably be doing it in your sleep.
I'll just stand behind this one comment I was a little pissed that someone called me out on your thread sorry about that
