MTC engineering is who I get my MTC parts from. They also have the springs I mentioned. I also should mention when you use their fibers you leave the anti judder spring and seat out of the clutch pack like up on the wall somewhere until you decide to pitch it
If I need steels I use the OEM ones. you can use busa ones but you have to make sure you use the right combination to get the correct stack height. Another reason to stick with the OEM 15.78 each plates. Hylomar works great I can get away with pulling the cover three times before I need a new gasket. You really need to open her up to inspect and see what your really need then order the OEM stuff from Hermy's
