I just bought a fidanza flywheel and greddy stage 1 combo, but there is a piece that accompanies this setup that adds about 20% strength. What was that piece?

 

It might be the chromoly pivot pin.

 

No that wasn't it. It almost looks like it has a hex pattern with a ball at the tip of it. Please help quickly guys so I can order the part.

 

I think you guys are talking about the same part.

Just the first example that came up on google...(This one's for the 2003, but they have a link to the one used on newer Z's too)

That was it guys! Thanks so much! I would have hated to throw a stock piece on there and have it break! Z owners to the rescue! Does anyone here have the clutch flywheel setup I just purchased? I read reviews and aside from chatter they seamed good.

 

Greddy makes clutches? Since when?

 

No you are right I was typing on my iPhone. Its an Exedy stage 1. I was looking at Greddy exhaust, so I had Greddy on the brain.

 

exedy stage 1 pressure plate isn't much stronger than stock so you shouldn't worry about breaking the pivot.
