I need to replace my clutch, think i am going with a king cobra, thoughts? Also while i'm in there i need to replace the speedo gear(guy before me never did 3.73s) and i may as well relace the stock drive shaft with an aluminum one( mine vibrates a little) Now what i was wondering is, is it worth it to get an aluminum flywheel? The car is my only car and a daily driver, and have heard it can have a negative effect. Your thoughts are appreciated.
