I'm gonna be having a new clutch put in soon, and decided I might aswell just do the flywheel too. I was looking at an ACT streetlight. Any thoughts on these? I read somewhere that you don't wanna go under 14-or 12 pounds or they may shatter, the street light wieghs 12.8. Any Truth to this? Any recommendations?

 

I wouldn't worry about it shattering, that's more a concern with lightened factory flywheels. You'll hear opposite ends of the spectrum on this, I love my 8lb Fidanza. The power seems to always been there, it climbs through gears faster as well.

 

"ACT streetlight flywheels" are pretty good
wouldn't worry to much about it shattering

 

Yeah... I would only worry about it shattering if you got it from a crappy manufacturer... you should be just fine.

 

Anybody have real knowledge like pros/cons? Im wondering too because the laws of physics say by taking away weight from a reciprocating assembly will not only allow it to be spun faster, but consequently to slow faster. if your playing around in a gear and let off the gas one would think the "engine brake" would jerk your head off. Soooo....anybody experience this?

 

the lighter a flywheel is the faster the engine will rev up and down.

 

A lighter flywheel give you less bottom end and more top end. Grenading comes from mis alignment in most cases, but I have heard otherwise as well...as long as it is name brand you should be ok.

I just hand my clutch done today. Exedy OEM replacement and 8lb fidanza flywheel. I feel a difference in pedal feel but that is all for now. In about 488 miles I let you know what I think completely.

 

I like my Exedy 9.5 lb The ring gear is milled, not pressed on. I think it makes the car easier to drive and it pulls and responds better at any rpm, I think it's easier to launch too actually.

 

I think the street light is kind of a good middle ground between daily driving and racing at 12 pounds. THanks for the replies.

 

I am running a 9lb Prolite and I wouldn't go any heavier. I don't see why you would want to go much heavier unless traction is an issue.
