lightweight flywheel

Im currently in the market for an aftermarket flywheel. I just have one simple question- are there any disadvantages to having one versus a stock unit?

You might accidentally spin your tires through first. Sucks.

A little noise, but well worth it.

IC engines produce power in pulses each time a cylinder fires. These pulses are very close together at RPMs above 1000 or so. Below that, when you are at idle, the pulses can be heard. The heavy stock fly wheel absorbs these pulses. Lighter fly wheels absorb it to a smaller degree. It sounds like chatter when you are sitting at a stop light. You can make it go away by pressing the clutch or bringing the revs up to 1000 or so.

No, your wheels won't spin all the time. Do some research. Check UUC's site, they have a TON of information on the product. The UUC is a Fidanza.
