Has anyone used Extreme Flywheels?

Can anyone tell me how their fuel economy was affected by using a lighter flywheel? Im thinking of putting in the billet steel or chromoly one. Just going for a tad lighter but not too much. Does anyone know the weights or how much lighter they are? How much they improved your ride and performance?

i have the 2nd lightest one in my car compared to stock (25%) lighter. i found i need to give abit more when i'm at the lights but the drivablility is good still. my friend has the lighter aluminium one and i found it to be not so bad as well.

we are both using it with the xtreme clutch and has changed the way how our cars drive. get it i reckon.

acceleration improves especially in gear changing !

Hmm..ok. thanks. Maybe they have enough mass still to provide good driveability?

Driveability and economy are important for me

Im probably going to be a chicken and get the slightly lighter billet steel one

Im happy if it will knock 0.3 of a sec off my times

What about economy..did you notice a fuel consumption increase?

And I also read they make your gearbox noisier?
