I'm thinking about getting a lightweight flywheel and possibly a clutch (thinking of UR/jwt combination). I am not sure if I need a new clutch though. As I understand, folks dislike their 05 clutches and change them to something like jwt or nismo for improved feel and control, but does anybody change the clutch on 04 and what difference does it actually make? I don't want to spend $$$ for something I don't need.
