Flywheel
 

Is an aluminum flywheel the best one to go with for our motors? Any situations where I would want to avoid one?

i have not heard anything... i picked myself up a used 03/04 cobra flywheel.
No one has told me that was a mistake...i will let you know if i run into any problems.

^That flywheel won't fit if you're using a stock clutch, the '03-'04 Cobras use a bigger clutch.

Only thing I've heard is that they sometimes throw the engine out of balance or you can feel some vibration because of them. I doubt it will be a problem and have never seen this personally. If it were me, running the power you are, I'd upgrade to an '03-'04 Cobra-spec unit, they're bigger.

that is what i did. came with the right clutch...

Depends what your looking for. What are your mods? Check out this video from Fidanza.

I run aluminum and love it. Although My Kevlar clutch did not last. The Ceramic should do the trick. I will be installing it this coming week.
