What are the advantages/disadvantages to having a light weight flywheel in a 5-Speed.

^^^can you elaborate on why it's harder to launch ?

Well basically its harder to launch because there is less rotating mass to get the car going. The stock flywheel/clutch is designed to create rotating mass, so that once it gets spinning, it is harder to stop.

It also affects daily driving - when the car is stock, and you let the clutch out too fast without enough gas, chances are it will bog down, buck forward, and keep going at idle speed. With the lightened flywheel, if you let the clutch out without enough revs, it will just stall out immediately - because there is less rotating mass to keep the engine spinning.

The benefit is that the car will rev faster - there is less mass to spin, so when you hit the gas, the engine will spool up pretty quick. It drives much differently (the car is usually quicker too), but once you get used to it, you won't even notice the difference.

Hope thats helps.

The light flywheels only really "shine" in auto-x events/road coarse racing, where you need the engine to rev fast for comming out of corners.

I do not reccomend it for drag racing for the reasons stated above.

Flywheel are suppose to be good boost fast rev means quicker spooling turbo thus geting power out of the turbo quicker and having less Turbo lag.
