I have an 02 wrx 63.000 miles on it and I know the clutch is dead. My rpms will always like slip and shoot up then down while the engine isnt catching. I am wondering what I parts I will exactly need to change it. People have recommended Exedy clutches and I read that when u replace the clutch it is better to upgrade the flywheel as well. Also my car is basically stock engine wise so would putting in a multi-plate clutch be a waste??Thanks
