It will work fine together. The stock flywheel is very heavy but works fine with the stage 2 Southbend.

Hi Joe! I needed to replace my slave for my 09 370z. I was wondering what would be a good setup for my stock Z. I am looking to change the clutch, might as well, if the tranny is going to be out. Was wondering if I can run the southbend stage 2 with my stock oem nissan flywheel. Or wil this create issues. Or is there a better set up that you would reccommend?
