    My few s50 questions

    I've got an ltw flywheel, a clutch disc, and now I'm looking for a pressure plate. I see a stock one and a sport one. My s50 should be around 250whp, should I opt for the higher clamping power pressure plate or will the stock one suffice?

    If I put the smaller output flange on my zf trans, will I be able to use my stock driveshaft? (86 eta)

    I'll update this as I have more questions, but I think these are my only ones. Thanks!

    1) Stock should be fine

    2) What's the build date? If higher than 9/86 then you have the 96mm guibo which will not work with the smaller output flange. If you have lower than 9/86 you should be fine. Unless you use the front half of a 325i driveshaft with your smaller output flange, you could run that.

      Thanks on the pp info, and with the driveshaft, as long as I have the proper sized output flange, I'll be ok? Meaning the length makes no difference?

        Ok, so, I've got a small guibo output shaft flange. The splines are different than my 5/96 build zf trans. Which it seems means that I now have to return my new driveshaft and get the proper one for the large flange. Unless anyone has any ideas?

          Couldnt you use the front section of a small flange car mounted to your rear half of your drive shaft and get it re-balanced.

            Your Eta driveshaft is the wrong length anyway.

              Gd it. So what driveshaft do I use? Late eta with large bolt spacing, e30 m3, or e36 328i?

                I got a 328i driveshaft now. Do you or do you not have to reverse the csb? I'm reading conflicting info here.

                  ^^From what I understand, you just use the E30 CSB on the E36 shaft.

                    I've got that much figured out. I just need to know which way to install it. Just like stock or like the 328 one?
