I am going to be installing a new transmission and clutch in to my 98 GS in about 2 weeks. I am going to get a SPEC Stage 3 clutch, and I am not sure if I want to spend the extra $450 for an aluminum flywheel. How big of a difference does it make? Currently I am basically stock, I only have an intake and a piece of sh!t muffler that the jack @ss who had the car before me put on. Can anyone tell me if the aluminum flywheel is really worth it, and also if they know of anywhere I could get a cheap SPEC Stage 3 clutch and aluminum flywheel.
